Friendly tip on how to get underweight lifeboats to manouver better: Have them slightly trimmed by the stern. Makes a huge difference, like shoes vs iceskates on ice.
I’m a Survival Craft Instructor based at Warsash Maritime School on the South Coast and have been recommended your videos by “The Algorithm”! One thing to consider regarding the ballast and stability is that these craft were designed to perform at optimum when fully laden with crew. In 2010, the calculated weight per occupant was changed from 75kg pp to 82.5kg pp, so dependant on the year she was built, you could calculate the expectant load of the occupants. We have found with our PELB and TEMPSCs that due to a restriction in capacity for training and removal of equipment from manufacture to convert to a training aid, weight needs to be distributed astern to get the best efficiency from the propeller. The flip side of this is that steering becomes lighter and less predictable due to the bow sitting higher in the water.
This is really helpful, thank you. There's so much obvious focus on getting the trim right port and starboard, but I'll put a lot of effort into getting it right fore and aft.
@@AlexHibbertOriginals You’re most welcome. It’s a interesting project and one I’ll be following closely. I’m guessing there’ll be plenty of supplies that can be stored around the boat to help find that correct trim. Reducing cavitation will dramatically improve speed, fuel efficiency and handling. The ducted propellor, should help with that a fair bit.
You could probably put a number of solar panels across the top to take some power load off of the engine, Maybe some retractable outriggers to counter some of the rocking at lighter loads. and would provide extra storage and area to move about.
Those design issues are a dream come true for my brain. I love building things in my mind and then putting them into practice for the results. I suppose problems are my friend.
Top tip to paint it, first use a coat of bright yellow and then an orange coat. The best quality paint is de IJssel Double D coating, mosreal professionalt
bolt an I-beam along the wee keel already there, with the flanges on the lower edge serving as a base when on blocks. You gain much needed keel stability of holding a course, the extra weight there helps with ballasting / loading. Composite ridges on the bottom angled and extending to the outer edge of the hull are an effective stabilizer for the basic hull shape, without trying to add active fins, gyroscope or paravanes.
@@AlexHibbertOriginals www.pacificboatbrokers.com/used-boats-for-sale/LS5377/trawler-groundfish-shrimp-boat.asp the pictures show the "ridge", although they are not very wide they are a stabilizer, wider gives more effect naturally but it is a balance.
Can you add a mast for a sail (without damaging the structure)? A sail could really help to extend your range/add a backup if the engine fails. Also helps with radio antenna. For a keel, perhaps an external board? Probably very obvious ideas.
a 10 HP SAAB with moving propeller is a good solution.less diesel and easy handling,because you use one direction for forward and backwards. verry good for manovering in small spaces arround.You move the propellerblades instead more or less gas.
Have you considered using a high performance anti fouling paint on the hull for better fuel economy? Large ocean going vessels can save a million dollars a year from one coating to another.
@@AlexHibbertOriginals hmmm, ~_~ Pontoons in mated pairs on each side for a total of four. these could be quick pin detached then floated behind the main hull. Have the attaching boom arms hinged so each set that can be raised. This would give you a Trimaran set-up for open water. But allow for narrow passage navigation in ice fields when needed.
Your boat has a displacement hull, which means it's top speed is limited to six knots, based on its length at the waterline. At the hull's top speed, adding more power simply digs a deeper hole at the stern to climb out of. Exta power is useful for rough water and headwinds.
Even fully loaded you will need the keel ballast - we did the 4 years crossing Europe to the Black Sea without it, with the boat loaded, and it made such a difference to add half a ton in Hamburg. Build space in now #boatingeurope :)
Thanks. Yes this footage was actually filmed some time ago (the footage was previously embargoed for other uses). I now have zones allocated for solid steel ballast, and will cover this in a much later video. Cheers!
I worked on a trawler the rolled like a big B we installed some wings either side and she completely changed to a weapon we worked some extremely rough weather i remember working in 92knots .
@@AlexHibbertOriginals I'll try but I think they were especially made for our vessel they worked like keels we pulled them in when heading across the bar and they stayed in intill we headed out again
Have you thought about adding additional - not sure what you call them, additional strips of fiberglass below the waterline to promote tracking? I was wonder also about the deck area by the rear hatch, seems very narrow - have you thought about adding an extension to that area? Cheers !
Hi, great video. Have you thought about getting a 2nd lifeboat and linking them together to form a catamaran? They would need to be about 5 metres apart to avoid hull wave interaction, so a deck structure out of scaffold or better still stainless 304L with expanded metal galvanised decking would give you a good working platform (I use galv decking on my boat and it has held up very well). Best of all build in some buoyancy to the deck structure and bolt it to the lifeboats and then you can fit a mast and lifting keel and should you capsize, you unbolt the lifeboats, let them self right themselves and then bolt the whole lot back together again. It will make for a stable, safe boat with tons of storage and deck space.
I didn't realize how small Alan was until seeing him on the water with a person onboard. It's amazing to think that tiny vessel could possibly be "rated" for 68 people!!! It looks like one would be hard pressed to get half that number in there!!!
I made a 6.5 ft long boat, 28 inches wide, 10 inch sides out of a folded 4x8 ft piece of corplast. Weighs 4 lb and cam hold 250 lbs. In reinforcing it with ski poles, crutches and 1/4 ply for a lake one mile away. Fits in trunk of car, sticking out. I may add a sail and a float bar to stop tipping. Cheers
Asking from professional curiosity, did you contact local coast guard/VTS before going for sea trials? It seemed that you went quite far out to the sea. I know from experience, that any sight of orange rescue boat would get the crew of a vessel a bit anxious and report it to nearest station. More diligent crew even could start preparations for rescue situation.
Hi Sander - the sea trial was only a very short coastal circuit, and the marks designating Alan as an in-service lifeboat were covered/removed. Whilst it's conceivable Alan's appearance, even after major physical alterations, could cause some radio chatter, we would be able to allay any concerns as we monitor the correct radio channel.
Top speed is a function of waterline, unless you get on a plane. Hull speed in knots = 1.35 times the square root of the waterline in feet. Your length is nearly 25 feet and supposing waterline is 20 feet, your hull speed is almost exactly 6 knots
There is a company that fabricates fold down "keels" that are mounted to the side of yachts to limit rolling and to give a smoother sail. Perhaps an idea like that might help.
I've looked at some of these options - spinning anti-rollers are very expensive and power hungry. Passive ones are more possible, but there's robustness to consider.
This is an interesting project. With cooking, heating, and even breathing, I imagine condensation will have to be something to overcome. The grey matter will certainly be taxed with this conversion.
This is an exciting venture! I'm not sea-farer, so I'm just ignorantly wondering if it would be possible to somehow arrange a tow to save on fuel? Like from a cargo ship heading in the same direction? Obviously, I have no idea if this kind of thing would even be practical or possible to arrange?
I suppose if you were able to have permission - but that would be doubtful. I'm also not sure of how the boat would behave if towed at more than its maximum hull speed.
Having probably a dozen hours going back and forth to a cruise ship I have encountered 30 degree rolls in a boat with about 60 other people. Several who were instantly sick. I am betting that stability and its cure are going to be your number one problem.
Why not use a lead ballast keel attached to the bottom where you removed all the old iron hardware? I realize, as you said that's dead weight, but making it lead and mounted on the bottom would give you the most stability for the minimum weight, while using points which were obviously engineered to take a lot more force than the keel would ever apply.
Actually, most of that dead weight was higher up, mounted on the boat, and it was awkward in size and shape. The plan is to add denser, more manageable ballast right down low in the coming months.
Ya, sorry for the confusion, I didn't mean mount it in the same place, just using those mounting points. If they're strong enough to lift the whole boat without damage, a keel would be nothing. You'd of course have to build some kind of mounting brackets to wrap around under the ship to where you want the weight mounted.
You could also make the engine a hybrid system. Put some electric motors strapped to the outside with some big batteries and solar panels to help keep them charged, and the engine and solar panels can keep the batteries able to run, while reducing fuel consumtion. :-)
Is Alan going to be a boat you have long term? If so then you should consider some type of fresh water cooling system. Maybe a keel cooler pipe or the addition of a heat exchanger and expansion tank. Also consider installing zinks both externally and in the engine cooling system. These are things likely not heavily considered during building a lifeboat. As they are meant to live on deco of a ship and only rarely touch water. So they’re likely not built to last while sitting in salt water. If this is a one time expedition boat that will then retire to a UK canal then your fine.
Alan will spend most of his time ashore, but is slated for multiple longer excursions. The engine currently already has a keel water cooling system for the engine. Is that what you meant?
@@AlexHibbertOriginals yes ok. I just didn’t see a heat exchanger and it’s integral expansion tank. Which are commonly (but not always) integrated into the exhaust manifold. But if you have keel cooling then that’s probably why I didn’t see it. As long as your engine has antifreeze in it rather then sea water then you’re going to be just fine. If that’s the case then disregard my comment on cooling. I was just wanting to make sure you are setting yourself up for safety and reliability. FYI once you get closer to knowing your final weight you’ll be able to have a prop shop adjust the pitch if you want a little more speed at lower RPM. They can cup the blades. Not as good as a new prop but it’s all a cost vs benefit thing. Definitely check you have zinks. I didn’t see them but that doesn’t mean they aren’t there. I’m really looking forward to watching this build progress. Cheers, Jeremy
Hey, I'm a naval architect who has actually studied how ship's lifeboats act in ice packs. Add "bilge keels" (or sometimes called "anti roll chocks") Just long fins at about 45 degrees to the bilge radius, about 12" sticking out x say 8' long. Could be fiberglass or alum. alloy or s.s. plate bolted to the hull. They can reduce roll by about 30-40% or so will little cost. If you're heading into real pack ice they will be torn off so make sure if they fail they don't damage the hull. Well pack ice will crush a lifeboat so avoid it too!
@@AlexHibbertOriginals This research paper gives a good overview of issues with operating TEMPSC's in pack ice nrc-publications.canada.ca/eng/view/ft/?id=e1396097-84b5-4981-a127-b1707733f262 Basically they spent a lot of time whacking lifeboats into ice :)
Very interesting. With such a short ‘keel’ is it possible to intentionally beach it on a sandy beach and it stay upright? Keep up the adventure! Looking forward to the mission. Safe sailing
im sorry if this is redundant, but how do you prevent Alan from rolling over or capsizing? He doesn't have a large wing under the keel.. thank you in advance
Excellent viewing . Does anyone in your team have experience in building /modifying a project like this? Asking out of interest only as I’m amazed what people achieve with or without experience. Good luck to you all with the whole project.
The original project team had a member with multiple ocean crossings under their belt. This is something I'll be looking to ensure continues before Alan goes somewhere serious. I'm very lucky also to have two marine engineers in my family, so there are plenty of calls and emails bouncing back and forth.
Thanks for your interest in the project. You're right to note of course that I'm not a professional helmsman or sailor. I'm a polar specialist. So, it's a knowledge accrual process, for sure!
@@AlexHibbertOriginals yeah right... boats can't type, birds are real, the moon landing actually happened.... Trying to avoid getting in trouble with youtube for disseminating conspiracy theories ;) I got you, "Alex".
Stupid question time, I’m assuming fuel equals ballast (some), as you use up fuel will you take on water to replace ballast? I know little about boats, this just cropped up on my feed.
It does. The most elevated fuel bladders/tanks will be consumed first, so CoG will improve and lower as time goes on. The fore/aft weight balancing between a laden and empty boat will be key to plan for.
@@AlexHibbertOriginals The VCG really affects roll periods. As it gets lower, the boar becomes more stable but the roll period gets faster. You might want a period of about 6 seconds (test by running back and forth with the boats roll and get it rolling at its natural frequency and then time say 5 full roll cycles, dividing by 5 to determine roll period for 1 cycle). A faster roll period means more stable, but is not as comfortable. Slower than 6 seconds or so means it doesn't have a lot of stability...If you are carrying lots of fuel then adding back water ballast as fuel is consumed is probably required, but maybe not the full weight of the fuel.
Question: having done your sea trial and determined that Alan rocks and rolls a bit do you envisage adding ballast or maybe a small keel. I watched the haul out after the trial and it looks as though a keel may be possible but you wont want to over come the self righting feature. There may be a small lee way there to add something to negate the rock and roll.
These are actually called TEMPSCs Totally Enclosed Motor Propelled Survival Craft. Not TELB. As you have taken out the air bottles for pressurising and stopping smoke ingress, you could remove the water spray pipework from the deck too.
TELB and TEMPSC are terms for the same thing. TEMPSC was coined by the USCG mid last century. Neither are wrong. The spray pipework is proving useful for all manner of things.
The hull shape is best for safety amongst sea ice, but as you say it will not aid sea handling. I plan to test whether significant ballast is enough. And yes on the power front - a number of ideas for backup power. To be announced!
Hi nice cédions can you tell me where I could buy one I’m looking at going from Vancouver Canada to the Philippines thanks and if you have any data on fuel mileage on any trip you have done would be nice if you can share thanks
Now that the boat is too light to float properly (!!!), how about installing [retractable] hydrofoils and air-propellers on a T-Tail that can be made cheaply of wood and fibreglass? 40HP should be more than enough with two 3-blade propellers and hydrofoils won't limit you to just 6 knots. Just thinking aloud...

I’m a Survival Craft Instructor based at Warsash Maritime School on the South Coast and have been recommended your videos by “The Algorithm”!
One thing to consider regarding the ballast and stability is that these craft were designed to perform at optimum when fully laden with crew. In 2010, the calculated weight per occupant was changed from 75kg pp to 82.5kg pp, so dependant on the year she was built, you could calculate the expectant load of the occupants.
We have found with our PELB and TEMPSCs that due to a restriction in capacity for training and removal of equipment from manufacture to convert to a training aid, weight needs to be distributed astern to get the best efficiency from the propeller. The flip side of this is that steering becomes lighter and less predictable due to the bow sitting higher in the water.
This is really helpful, thank you. There's so much obvious focus on getting the trim right port and starboard, but I'll put a lot of effort into getting it right fore and aft.
@@AlexHibbertOriginals You’re most welcome. It’s a interesting project and one I’ll be following closely. I’m guessing there’ll be plenty of supplies that can be stored around the boat to help find that correct trim. Reducing cavitation will dramatically improve speed, fuel efficiency and handling. The ducted propellor, should help with that a fair bit.
I would add some shield in the front or sides for when going into the artic ice or smashing into solid objects
The only seagoing this thing should be doing is on golden pond

You could probably put a number of solar panels across the top to take some power load off of the engine, Maybe some retractable outriggers to counter some of the rocking at lighter loads. and would provide extra storage and area to move about.
You could always add additional skegs underneith. These could be used as runners for any over land travel that might be required.
Also otter boards.

To make it more stable in the water add a seakeeper gyro or perhaps build one?
She does have some serious roll. Do you plan any ballast underneath, because it could become quite uncomfortable over a long period of time.
Get a RSJ aluminium and use it for a keel,bilge keels good as well stops the rolling I've had 6 life boats with and without keels.

to keep from rolling....you can put on retractable side floats like you see on some canoes. One one each side pulled up until needed.
Cheers, Alan is a great name for that vessel!
Have you considered using a high performance anti fouling paint on the hull for better fuel economy? Large ocean going vessels can save a million dollars a year from one coating to another.
To lessen the roll and provide both stability and fuel/supply storage a pair of Aluminum outrigger pontoons made from a used pontoon boat..
Unless easily retracted, they would be susceptible in icy waters. The fixings to brace them to the hull would mean very serious structural work.

With your center of gravity so high did you plan about designing some weighted keels or perhaps a pontoon.
Ballast yes - pontoon no!

Whilst it's conceivable Alan's appearance, even after major physical alterations, could cause some radio chatter, we would be able to allay any concerns as we monitor the correct radio channel.
How about a heavy steel keel to carry fuel and ballast the boat? You could even get clever and fit a lining so the space could be filled with water.
Steel is going to be the solution, but precise placement will need another sea trial.
Top speed is a function of waterline, unless you get on a plane. Hull speed in knots = 1.35 times the square root of the waterline in feet. Your length is nearly 25 feet and supposing waterline is 20 feet, your hull speed is almost exactly 6 knots

You'd of course have to build some kind of mounting brackets to wrap around under the ship to where you want the weight mounted.
have you reached out the designers and engineers that created the boat?
They routinely don't engage with users of decommissioned TELBs. No commercial incentive, and perhaps legal liability.
@@AlexHibbertOriginals What a shame. Keep uploading. The Internet will hook you up ;-)
GOD is in control!!!! Hallelujah praise GOD!!!
Alan is in control.
You could also make the engine a hybrid system. Put some electric motors strapped to the outside with some big batteries and solar panels to help keep them charged, and the engine and solar panels can keep the batteries able to run, while reducing fuel consumtion. :-)
The solar panels would need to be around 10x the size of the boat.
Is Alan going to be a boat you have long term? If so then you should consider some type of fresh water cooling system. Maybe a keel cooler pipe or the addition of a heat exchanger and expansion tank. Also consider installing zinks both externally and in the engine cooling system.
These are things likely not heavily considered during building a lifeboat. As they are meant to live on deco of a ship and only rarely touch water. So they’re likely not built to last while sitting in salt water.
If this is a one time expedition boat that will then retire to a UK canal then your fine.
Alan will spend most of his time ashore, but is slated for multiple longer excursions. The engine currently already has a keel water cooling system for the engine. Is that what you meant?
@@AlexHibbertOriginals yes ok. I just didn’t see a heat exchanger and it’s integral expansion tank. Which are commonly (but not always) integrated into the exhaust manifold. But if you have keel cooling then that’s probably why I didn’t see it.
As long as your engine has antifreeze in it rather then sea water then you’re going to be just fine. If that’s the case then disregard my comment on cooling.
I was just wanting to make sure you are setting yourself up for safety and reliability.
FYI once you get closer to knowing your final weight you’ll be able to have a prop shop adjust the pitch if you want a little more speed at lower RPM. They can cup the blades. Not as good as a new prop but it’s all a cost vs benefit thing.
Definitely check you have zinks. I didn’t see them but that doesn’t mean they aren’t there.
I’m really looking forward to watching this build progress.
Cheers,
Jeremy
Any thoughts of reinforcing the bow to deal with the potential of encountering random sea ice?
Many thoughts - no decisions just yet.
Have you not considered the idea of putting a bit blast in the boat for when your running slight on fule and supply's?
Certainly have! Will detail later.
I wonder how much it rolls when there are waves.
A lot! Something to be tackled later on.
Hey, I'm a naval architect who has actually studied how ship's lifeboats act in ice packs. Add "bilge keels" (or sometimes called "anti roll chocks") Just long fins at about 45 degrees to the bilge radius, about 12" sticking out x say 8' long. Could be fiberglass or alum. alloy or s.s. plate bolted to the hull. They can reduce roll by about 30-40% or so will little cost. If you're heading into real pack ice they will be torn off so make sure if they fail they don't damage the hull. Well pack ice will crush a lifeboat so avoid it too!
@@AlexHibbertOriginals This research paper gives a good overview of issues with operating TEMPSC's in pack ice nrc-publications.canada.ca/eng/view/ft/?id=e1396097-84b5-4981-a127-b1707733f262 Basically they spent a lot of time whacking lifeboats into ice :)
@@evangatehouse5650 Thanks - yes had a good read of this and others in the lead up to the purchase.
@@evangatehouse5650 Thoughts on this? seagrant.uaf.edu/bookstore/boatkeeper/bilge-keels.pdf
Very interesting. With such a short ‘keel’ is it possible to intentionally beach it on a sandy beach and it stay upright? Keep up the adventure! Looking forward to the mission. Safe sailing
Certainly possible, although you'd be lucky to sit perfectly upright. On ice, supports will be needed.
im sorry if this is redundant, but how do you prevent Alan from rolling over or capsizing? He doesn't have a large wing under the keel.. thank you in advance
It's self righting due to the layout of weight and internal buoyancy foam.
dude rolling is the one you dont want. Ballast is your friend
Can't wait to see you get big brother!!! Don't forget me when you hit 100,000 Subscribers. This build will get alot of media views.
I have to admit I'm pleasantly surprised at the acceleration in views!
How much old use life boat prices?
“Alan was ready for having his innards drilled” 😳🥵
Excellent viewing . Does anyone in your team have experience in building /modifying a project like this? Asking out of interest only as I’m amazed what people achieve with or without experience. Good luck to you all with the whole project.
The original project team had a member with multiple ocean crossings under their belt. This is something I'll be looking to ensure continues before Alan goes somewhere serious. I'm very lucky also to have two marine engineers in my family, so there are plenty of calls and emails bouncing back and forth.
@@AlexHibbertOriginals Thanks for your reply , the team and extensions of the team sound qualified to the max.
Thanks for your interest in the project. You're right to note of course that I'm not a professional helmsman or sailor. I'm a polar specialist. So, it's a knowledge accrual process, for sure!
Where is the best place to buy one?
Extra weight will not stop it rolling. Why it has that hull form I cannot imagine..
Best luck - waiting for more :-)
Thank you 😀
@2:34 "we filled the gaps with 5200"? What is 5200?
3M 5200 adhesive. There's a 'products mentioned' section in most video descriptions.
Thanks Alan. I was watching your 8th episode and you mentioned it as "3M 5200" so I managed to find out what it was.
Oh I'm Alex. The boat isn't answering questions just yet, but I'm training him up.
@@AlexHibbertOriginals yeah right... boats can't type, birds are real, the moon landing actually happened....
Trying to avoid getting in trouble with youtube for disseminating conspiracy theories ;)
I got you, "Alex".
You culd make the film 10min long and I promise I vuld not get bored. Intresting project 👍👌
This is very interesting!
Stupid question time, I’m assuming fuel equals ballast (some), as you use up fuel will you take on water to replace ballast? I know little about boats, this just cropped up on my feed.
It does. The most elevated fuel bladders/tanks will be consumed first, so CoG will improve and lower as time goes on. The fore/aft weight balancing between a laden and empty boat will be key to plan for.
@@AlexHibbertOriginals The VCG really affects roll periods. As it gets lower, the boar becomes more stable but the roll period gets faster. You might want a period of about 6 seconds (test by running back and forth with the boats roll and get it rolling at its natural frequency and then time say 5 full roll cycles, dividing by 5 to determine roll period for 1 cycle). A faster roll period means more stable, but is not as comfortable. Slower than 6 seconds or so means it doesn't have a lot of stability...If you are carrying lots of fuel then adding back water ballast as fuel is consumed is probably required, but maybe not the full weight of the fuel.
Question: having done your sea trial and determined that Alan rocks and rolls a bit do you envisage adding ballast or maybe a small keel. I watched the haul out after the trial and it looks as though a keel may be possible but you wont want to over come the self righting feature. There may be a small lee way there to add something to negate the rock and roll.
It's oft-discussed in these comments sections. Watch this space!
So how to ensure stability once supplies dwindle down towards the end of the expedition?
Plenty of steel ballast too - it won't just be supplies. But I agree - a careful calculation to make.
How much did pne of these cost ?
These are actually called TEMPSCs Totally Enclosed Motor Propelled Survival Craft. Not TELB.
As you have taken out the air bottles for pressurising and stopping smoke ingress, you could remove the water spray pipework from the deck too.
TELB and TEMPSC are terms for the same thing. TEMPSC was coined by the USCG mid last century. Neither are wrong. The spray pipework is proving useful for all manner of things.
Do they have air bottle for pressuring?? Why??
Did you end up getting the Chinese one or the Norwegian life boat. It looks great! Like new!
The Norwegian - a Normar.
@@AlexHibbertOriginals i wouldn't want a Chinese lifeboat either
What was the cost of the boat?
hi i really like the videos how much did it cost to ship it from Scotland ?
It's hard to say as the price was inclusive. Perhaps £500-1000.
Will you add a Keel to reduce rolling? Having only one method of propulsion would make me quite nervous. Oars don't seem Practical. An Outboard?
The hull shape is best for safety amongst sea ice, but as you say it will not aid sea handling. I plan to test whether significant ballast is enough. And yes on the power front - a number of ideas for backup power. To be announced!
Hi nice cédions can you tell me where I could buy one I’m looking at going from Vancouver Canada to the Philippines thanks and if you have any data on fuel mileage on any trip you have done would be nice if you can share thanks
Tough question in Canada I'm afraid. They are usually sold near breaking yards or oil industry areas. Plenty in SE Asia.
great project and nice to see it at dauntless by the way :)
I'm glad you like it. The crew at Dauntless are excellent.
this life boat is it safe at deep sea surley even in a heavey storm
Now that the boat is too light to float properly (!!!), how about installing [retractable] hydrofoils and air-propellers on a T-Tail that can be made cheaply of wood and fibreglass? 40HP should be more than enough with two 3-blade propellers and hydrofoils won't limit you to just 6 knots. Just thinking aloud...
Alan's ego is just too large to allow him onto the plane.
How much was it to buy?
I don't know why, but I really want one of these lol
Where can i buy a life boat
Every person you meet you could say:
"we've been at sea for months!"
Ain't that the truth.
