No. Remove it completely. It’s so annoying. It’s a scourge across UA-cam. I wanted this information so badly but I simply could not stay past 30 seconds. It’s absolutely maddening and senseless to have music going behind this.
For bluewater cruising, I like comfort and safety more than speed, therefore a modified full keel with a skeg rudder is my preference. For better maneuverability in a marina, a bow thruster is a big help. The only annoying thing was needing to go back several times and replay due to the 'music' blotting out your voice. Thank you for these keel instructions!
some people just naive as its gets, what exactly safety wise does a full keel give except of a big bulky space where you hit things without worrying it fell off you bottom ! my choice is a twin-keel or double keel, its best overall. its in middle of tringle safety and comfort and a bit speed. for a living boat can't go better. a Full keel usualy about 2 meters unter watter, so safety in coast region is huge problem running on ground. besides if you do, then you either fall one side or another, makind you boat lying sidewise on a coral rife or ground near cost.
@@bestvideos4ever1 Full keel gives you the option to heave to or lie ahull reliably. Which are both important safety techniques for open ocean sailing. That said, both can be done with other keel designs, but full keel is generaly the best for both as it offers the most lateral resistance - which is also great for rolly anchorages but comfort is mentioned in the video. Compared to your keel choice, full keel protects the rudder (as most twin keels are paired with spade rudders, no skegs to be found) from impacts and loose lines in the water. Also, full keel hull might point better to windward which is a safety factor for sailing in places where you have a shore that you could run aground on straight to leeward - but that can't be said wihtout comparing two specific boats, hence the 'might'.
Some very important details were left out here. Maybe mostly important that the keel also creates lift in a very similar way as the sail does. Another left out fact about winged and bulbed keels is that their main purpuse is not so much the added weight for countering heeling but rather to reduce water flow from the high pressure side of the keel to the low pressure side of the keel as this unwanted flow creates vortices and induced drag which slows the boat down. I highly recommend the book "The physics of sailing explained" by Bryon D. Anderson which goes through all this and more in very fine detail including lots of equations to prove the physics behind it all.
Because sailboats have masts they generaly have a high metacentric point. To compensate this, the boats are usually outfiited with a weighted keel to lower the center of gravity.
Great video and you explained things well. I notice that many people said you left things out and I hate being one of those people but, I'm going to be one of those people. Bolt on verses integrated keels. Most new bolts come with bolt on keels which are much more prone to breaking off. The integral keels are built in as part of the hull making them much more stable and safe, important if you are on a blue water boat.
I'm currently sailing on a volvo 70 and I have to say, performance wise canting keels are phenomenal. They easily increase speed by 2-3 knots and provide much stability and less heeling as well.
Lots of great information, great format and the humour is a great part of keeping interest. The music I must agree with others is more of a distraction than anything else. Keep up the great work and I look forward to seeing more great videos.
Great starter video for beginners. The "comfort speed maneuverability" triangle is excellent. Wing keels seem great unless you run aground at which point it can turn into an "anchor" and make it difficult to pull the keel out of sand or mud. Of course this should never happen...
I've been waiting for this exact video to come my way and here it is. I'm just learning about sailing and all the different keel types had me baffled. I live off a huge tidally influenced river the Columbia. Wondering what would be best type of sail boat for my area. Very helpful.
I think your video was very informative. I did not know the different effects on sailing that each type of keel made. I also want to say that you have a voice that doesn't make the video seem boring. Thank you
I "feel" it much better now. I was thinking, off-hand, the fin keel just "pressed against" the water sideways to counter the sail wanting to roll the hull over in the opposite direction, but it's actually, also (mainly?) pulling down and wanting to sort of "center" or "right" the boat at all times. Thank you.
I would like to add the "multiple keel" category for catamarans and trimarans. Also explain the roll at 3:30. The center of mass of the keel MUST BE below the center of buoyancy of the ship in order to be stable in roll. Also also, is it possible to make a similar video about sail types ?? Good video, keep it up !!
hahaha love your comment! I went from a sailfish, to a day sailer to a racing skiff to a ocean 42 Irwin, back to my little little yellow styrofoam picnic going shore to shore (across a mile of lake)love bug. I would always take my mom with me, and she would trail her hand in the water shouting “wheeee”, as I tried to keep it upright and forward. Someone with a beef chopped it up and sunk it in the shallows. I waS so heartbroken. Now, at 70, I am thinking of getting a oday again.
Hey I appreciate the video very informative don't change the thing you explain things well and I am definitely one of those beginners that is 101 for dummies and you made it quite clear for me to understand, PS I've seen your doppelganger here in Arkansas I see him quite often
Purposely bald heads are even MORE uncomfortable, and i am having extraordinarily difficult experience resisting my powerful impulse to click away and downvote.
I have owned three types, a SeaSprite 23 with a modified Full keel, a GP14 with a centreboard/lifting keel, and A montgomery 17 with a Hybrid keel/centreboard with the centreboard housed in a smaller "stub" keel beneath the boat. I prefer the Modified Full keel for just going for a sail, the SS23 would put her rail down and just go. No muss, no fuss, and very few surprises that can be inherent in other less stable designs.
I don't really even know how to sail really, found myself on here somewhat accidentally, and caught myself grinning for most of the video and watching it to the end. Funny guy. Thanks! P.S. Also, useful info.
Shane Acton sailed Super Shrimp, an 18' yacht, around the world in the 1970s. It had a double keel, which I guess must have been a bilge keel. He loved that he could bring it up onto the shore and stand it up on its double keel.
I love Dutch barges & think they are very handsome boats, if they could cruise well & I could afford a boat they would be my choice hands down, esp for the shallow English waters.
You know there are THREE categories of underwater appendages: KEEL Types which you covered in the current video ( bravo!) Also, there is the CENTERBOARD category( also used with KEELS) and the then the DAGGERBOARD category.....yup that's it, right? The total of sailing total history in three (3) groups REALLY? JUST 3, is the complete advancement of the underwater design excluding hydro foils which lift the boat. You did a great job presenting the many variants and issues of speed, shoal draft and a touch on safety. But really, with all the developments in sails and rigging it's taken hundreds of year's to address speed with SAFETY! NOW there is finally a FOURTH ( 4th) division of underwater appendages.... SCABBOARDS are the latest division of lateral direction stability that offers All the benefits of speed and performance , but most importantly SAFETY. As you pointed out in your video keels are fixed fins ( with in some circumstances LIFTING, that is to say Can be cranked up/ lifted over a period to provide for shoal draft but more so, not quickly to provide for safety for the crew, hull, or standing rig from shock. Typically, other than FULL KEELs impact with a submerged object causes much substantial damage and potential sinking due to breaching of the hull. CENTER- BOARDS like Leeboards rotate aft to relieve the impact, however, this moves the center of effort aft effecting helm and altering& negating the blade/foil. SCABBOARDs are a completely different mechanism, but offer the instant SAFETY of a CENTERBOARD without the rotation and alteration of the FOIL shape while maintaining the Hi-Aspect section for speed & performance. SCABBOARDs can be controlled to adjust the wetted surface dependent on the point of sail. Additionally, unlike CENTERBOARDS SCABBOARDS are not serviced below the waterline rather like DAGGERBOARDS they can be removed from above deck. However, unlike DAGGERBOARDS they do not extend above deck obstructing movement not adding windage. SCABBOARDS , a FOURTH division! Want to learn more? Let's talk Njsea7@gmail.com
I liked and subscribed at go watch a cat video .Pluss you covered bilge keels . Most you tubers leave them out. Like yea let's not talk about the only boats that don't need slip fees and can live in the estuary for free. If a boat falls over when the tide goes out what use is it 🤷 Great video mate .
Also remember some full keels are bolted on and some are "fully encapsulated" within the hull of the boat I believe this is the best design as you can never loose your keel.....it cant snap or be knocked off
Unless it fractures the hull and begins to flood. I just saw a video of an encapsulated keel boat being put to dry dock for maintenance. The weight of the boat being set on the keel caused catastrophic cracking. Apparently, the couple were preparing for Atlantic crossing. I believe their channel is called Pat and Frankie, if you’re interested in checking it out. I believe the mishap occurred last week.
I agree absolutely, it's what I want to know first, not all the other stuff e.g CC or stern cockpit etc. Then I want length waterline LWL. After that it's the design of the boat and comforts. But Keel FIRST. Yacht sales websites mostly don't even look at the keel type you have to trawl through the info to find a diagram hopefully that shows detail. Sometimes it's completely neglected.
VERY GOOD! - Sod off if I'm in a hurry, eh? Lol... Excellent video! Two questions: Q1: Canted bilge keels? (Keels could alternatively be used as ballast(s) with batteries inside as the ballast. Q2: What about low profile/horizontal sails? Seems counter-intuitive but someone I know wants to do it with a low 'X' profile of sails, bilge keels, and structure. Q2(A): Any advantage to catching wind off the top of the water?
I've seen on some larger sailing ships and motor yachts a type of hull with a "hybrid" dual keel design. A mix of Bilge Keel and Full Keel. They look like humps that run 3/4's of the hull's length under water. They are rounded and look like bulges. Have you seen this design before? I would think they add ballast under the waterline and add stability almost like a catamaran's dual hull.
we have a long fin (as in wide, not deep) on ours and with all things it is a compromise but it serves us well. Most long term cruisers and liveaboards will spend 90% of the time at anchor or in a slip if they have a few more pennies so at anchor comfort is also a very large consideration..
Nice, I am looking at making a small(14ft) boat with bilge/daggerboards. I think this design will give good performance, while not taking a lot of space inside the boat.
If you are looking to build a phenomenal little sailboat and want virtually FREE video Tutorial on it , Check out Allan Mullholland and his channel WAVE ROVER. He just built an awesome micro blue water sailboat
A New and "wild" design being tested in offshore vessels is the " Hinged/Free Ballast Keel " these are attached to the hull on a large hinge that swings free from port to starboard and has a heavy bulb at the base. This keel is ALWAYS vertical to the waters surface and ocean floor ( mostly ) no matter how the vessel is heeling. While loosing an aspect of weight in ballast by the keel not being fixed to the hull, it does eliminate weather helm and increases upwind performance and boasts a 15-20% increase in speed. In heavy winds it can be tightened to different degrees to prevent knockdown making it more traditional in design. It can also be winched to a large degree in either port or starboard directions to achieve a very shallow draft if needed. Not sure if it'll make an appearance on a production vessel , but never say never.
@@Reiv311 and why would it ? There is only 2 vessels with prototypes and neither is finished or "pretty" enough to boast the design OR give anyone else fabrication ideas to copy it before the utility patent is granted
Good info thanks. I would like to cut out my long keel, split it in two to make into twin bilge keel for beaching and shallow waters. But time is an issue its 23cm wide, would have to drill it to find out whats inside.
Wing keels have fallen out of favor with cruisers, mostly because of grounding. In mud and sand, the wings can kedge into the soil, making getting off the ground very hard.
I've been wondering why modern sailboats, even the bluewater oriented like Amel and Hallberg Rassy, never use full keels. Most commonly they use wing bulb keels. Is it because of the thecnologies that help sailors avoid rough storms, reducing the weather risks? Or is it that modern hull design can provide as much stability and confort as a full keel.
Whatched a video filmed inside the Hallberg Rassy boatyard and the boats under construction had fin keels with bulbs. It occurred to me that the developments in hydrodinamics (introduction of "wing effect" via bulbs) and materials (very heavy lead keels) might well have brought a solution of high stability without as much drag and lack of turning mobility as traditional long keels. Of course, the evolution of materials may also have allowed lighter hulls, overall compensating for heavier lead keels 🤔.
My boat is the famous Vega that has a modified full keel and she’s only 27ft but can easily do 7 knots which is fast for a small boat but she tracks well too.
Great video man, drop the music to like 35% of current volume and you're golden :)

I wish I could find a list of boats by keel type. I have tried to look for this but have not had much luck.
That's actually a really good idea for a resource on the website. I'll look into it.
I agree absolutely, it's what I want to know first, not all the other stuff e.g CC or stern cockpit etc.
Then I want length waterline LWL.
After that it's the design of the boat and comforts.
But Keel FIRST.

Sometimes it's completely neglected.

Wing keels have fallen out of favor with cruisers, mostly because of grounding. In mud and sand, the wings can kedge into the soil, making getting off the ground very hard.

I've been wondering why modern sailboats, even the bluewater oriented like Amel and Hallberg Rassy, never use full keels. Most commonly they use wing bulb keels. Is it because of the thecnologies that help sailors avoid rough storms, reducing the weather risks? Or is it that modern hull design can provide as much stability and confort as a full keel.
i'd like to know the answer to this one.
@@emmaearnshaw3282 Me too :). Maybe the publisher of the excelent video can enlighten us on that subject. Let's see...
Whatched a video filmed inside the Hallberg Rassy boatyard and the boats under construction had fin keels with bulbs. It occurred to me that the developments in hydrodinamics (introduction of "wing effect" via bulbs) and materials (very heavy lead keels) might well have brought a solution of high stability without as much drag and lack of turning mobility as traditional long keels. Of course, the evolution of materials may also have allowed lighter hulls, overall compensating for heavier lead keels 🤔.

Excelente tu video, muchas gracias Voy a acondicionar un Lightning quiero suprimir la orza abatible por una longitudinal más corta , que me sugieres?
My boat is the famous Vega that has a modified full keel and she’s only 27ft but can easily do 7 knots which is fast for a small boat but she tracks well too.
