If you're going to have multiple 12v items, I suggest having a 12v battery bank & bus rather than a bunch of converters. Several reasons for this. It's another layer of redundancy (your entire 24v system can go down, but your separate, mostly isolated 12v system might stay up. The battery will also help with sudden peaks in current and not stress the converter so much. It's also more capacity. Anyway, if it were me, I'd connect the victron 24 / 12 to a 15 to 50 amp-hour 12v battery. Then run all your loads off that.
Also, all the converters add up to more loss. Each converter has a loss of so much %. Normally around the 8% mark for low power stuff and more potentially for bigger stuff. Each of these little losses add up and the whole thing becomes extremely inefficient. I would also recommend NOT using 24 to 12 volt converters as you are generating great loss again. For best bet, get 24 to 13.8 converters. This is a higher end unit than you are portraying, but even it is only 90% efficient: au.mouser.com/datasheet/2/685/ds_vi_200-3045040.pdf Your boat, your choice mate, but I totally agree with this person!
Hi Alex. Best of luck with the final preparations. I was just out walking my new Springer pup when I met a woman with a dog called Alan. I thought to myself that Alan must be chuffed to have a dog called after him! Keep up with the good work. Ciao. Mark K Barge M V Sarah. Dublin, Ireland.
Wild to think that the months of watching Alan has grown and matured from a simple dingy of a lifeboat into a fully fledged exploratory and or research vessel nearly ready for the first full mission.
The nuts on your turnbuclles will work themself loose. In the middle of the turnbuckle is a hole, put a stiff cable through and the ends of the turnbuckle so it can not unsrew itselfon either ends. Happend to me on a little sail dinghi. The mast came down. Can not recomment 0/10 stars. Have a fun day
Mast is looking good 👍 Just a couple of points that make me wince. The main thing that I really don't like (as a rigger) is at 2.26 - where the two wires that brace the horizontal spar go to a u-bolt on the mast, you'd got one on the top leg of the u, with the other on the bottom leg. I can't see what stops the lower wire being knocked/vibrated to the top of the u-bolt, with consequent loss of tension? Anyway, in its current configuration, the two wires are trying to twist the u-bolt. I know this is all a very small setup with minimal loads, but you're usually so attentive to detail I thought I'd say something! The other thing is really trivial, but I'd love to give you the excuse to break out that grinder with skinny disc, and cut those nasty looong bolt ends at the masthead 😁 they look lazy😉 Nothing else to moan about. Hope you are managing to not get too stressed by the inevitable last-minute rush of endless minor tasks before the off!
@@AlexHibbertOriginals just from experience, hopefully I'm wrong, and I can't give you an exact reason other than that I just don't think they'll last. I think the plastic will break down with the salt and UV very quickly. Same reason you don't use white cable ties outside. I enjoy the videos, looking forward to seeing her at sea!
I'm curious what it cost for one full tank for Alan. Years ago while I was in college I did handyman work for extra cash. On one job I planted some very expensive trees for a gentleman who, I found out, was a yacht broker. He and his wife invited me in for lunch and he mentioned that he had just returned from picking up a yacht in Alaska and running it down the coast to Seattle and he mentioned how much it cost to fill the fuel tank (once) and I remember thinking "holy shit. That is the cost of my entire college education there. One tank of gas for this boat." Alan appears a good bit more frugal in his consumption though.
I am beginning to think this was the secret plan all along. Low Earth orbit and then descend when the weather permits straight onto the ocean next to the ice.
You'll most likely never see this comment, but I'll write it anyway on the off chance you might. Your horn needs a relay to operate correctly. The button turns the relay on or off with full voltage coming from the relay. Simple to do and plenty of diagrams around so no need to post a how-to here.
I read 'em all! Thanks for that - certainly the case in most setups, but I don't think the issue here as all the components are rated for the full 5A load and it worked direct to a battery.
@@AlexHibbertOriginals Yes, certainly the horn will work directly jumped to a battery for a quick test, but that is not how they are designed to operate for the long haul, the momentary switch will fail. Take 2 minutes and check a horn wiring schematic. Alan will thank you for doing so.

Hi Alex.
Best of luck with the final preparations.

I thought to myself that Alan must be chuffed to have a dog called after him!
Keep up with the good work.
Ciao.

I approve all round!
It's all happening! Very exciting, and I hope you get all the diesel you need.

I concur that a mast staying up is a strong preference.
Drinks on the House for Alan! Looking good!
So exited for the launch!
Me too!
Great to see another one 👍👍

Nice update. 2x👍
first, can't wait to see the finished product
You and me both..... 😂
you do lovely videos
If I may suggest. You should wrap rope around all your railing so you have better gripping.
Use monel locking wire on all rigging screws.
Turn buckle need wire locking. UA-cam is full of instructional how to vid's.
Got you some fuel in litres and a beer!
Cheers! The latter will be as needed as the former.
You should only need snug the nuts onto the tube to act as jam nuts.
Very good l, I think your led lights wrapped around the mast are going to last approximately 12 hours in the salt though.
Why? They are IP68 sealed, and bonded to the mast with Bostik.

I'll certainly report back if they fail!

Depends on the fuel tank size! Alan has a 100L main tank and then one or more 400L aux. We pay £1.50 per litre at the pump. About 30% less in bulk.
✌😎✌
Your reflector is invisible to vessels approaching from behind as the mast covers it.
If the mast if fiberglass, perhaps not. Radar waves travel straight through FRP.
The reflector will ALWAYS be hidden by the mast from one direction, unless it's on top.
for just a moment....yikes .....Alan in low earth orbit ....
I am beginning to think this was the secret plan all along. Low Earth orbit and then descend when the weather permits straight onto the ocean next to the ice.
Alan doesn't have enough explodey bits to get to orbit.
@@Garryck-1 Yet... :D
I just hope, you don't Encounter any US Navy Seals. I have just watched Captain Phillips lol. 😂

Okey will do
Your turnbuckles don't need anything but opposing tension from the nuts as the swivel is a tube nut anyway making the nuts "lock" nuts.
Does Alan have a shower?
No! But crew are free to stand on the deck.
