Congratulations on the not so soon to be born baby.
This thread has enough substance to support a whole forum in itself! A lot of good ideas already, so I have been beaten to it.
I understand the KISS principle and I sympathise with it as I have spent far too many hours maintaining and fixing stuff than I would like, but I also like my comforts. I'd probably go a bit more towards comfort than you may like, so I apologise if these suggestions may not properly take account of what you want, they have my bias.
I love the basics. Alu light sealed non-leaking structure, standpipes. waterproof bulkheads, raised saloon
and protected all weather helm
, big mechanical space and storage
Both are a necessity in many parts
of the world, not a luxury. Unless you are going into places where water temperatures are below 5deg C a reverse cycle air con system is very effective and efficient, no less efficient than a drip heater. I would insulate the boat very well, ideally control all the ventilation mechanically as once you have got insulation
under control most heat/cooling is lost
in ventilation. With good insulation
and controlled ventilation the heating/cooling requirements of a boat will be tiny and much, much smaller than is usually provided in boats. With your tiny sized air con/heating system it will be possible to run it off batteries through an inverter
and to run it 24/7. This will mean you will need a small generator
, find it affordable to run heating/cooling and you will enjoy it because it doesn't cost much and improves comfort particularly valuable when it is hot and heats/cools every cabin
. My air con has involved only about a day of maintenance
in 5 years replacing a failed pump. The genset - no problems at all (Onan). Not the worst area of the boat for failures, so I think an area for KISS to be compromised.
I have an a/c Linn amp and quality overhead speakers in each area. Cockpit
, owner's and guest cabin all fed from MP3s on the PC. Great sound and not optional equipment
in my view.
. Big thumbs up for these. Mine have been great. Not many dissenters out there.
lots of advantages. It means you can ditch the noisy ugly wind
turbine, gives tons of quick charging
power and you probably need it for full heating/air con and all the other luxuries. I realise it will take a lot to sell the genset to you.
To keep the genset near to fully loaded in use and therfore efficient, you will need to remove all peak loads from it, so I would run all a/c pumps through inverters or soft starters or make them DC and run them off the battery/inverter. This might also mean a DC slow output watermaker
like the katadyn
. This also has the result that you need a smaller, lighter, more fuel
efficient and cheaper to buy generator
. I suspect the smallest 3 cylinder kubota based unit you can find will work fine if you design the boat along these lines.
I'd go for the Victron or Mastervolt charger/inverters. Victron also do a super light, seemingly switch mode isolation transformer. I don't know how that works. I wonder if it is suitable?
I note it is on the port side in the picture, shouldn't it be on the starboard side? I think it would be tidier up the mast
though. I'd think about making room for the new Simrad
Halo open array type. Looks like a game
Seems missing. I would fit one. What, he is advising the anchoring
guru of something to do with anchoring
. What impertinence.
Water tank/water maker
I'd go for smaller tanks
than you suggest. It seems to be the trend on new builds as if you have a watermaker
you don't need a big tank. I'd have moderate tanks though as you may be sitting out in a stinky harbour for a week where you can't run the watermaker. I'd make the extra tank a fuel tank
instead and carry a decent hand held emergency
r/o unit in case it fails on a big crossing.
Probably not a helpful suggestion for you as it may change the boat too much to be viable: it seems to me that a dinghy
or even on deck is hideous, blocks the view and in extremis is not especially safe. A boat with a dingy on davits
or on deck is essentially a bigger boat, so why not build it bigger anyway. It would give extra waterline and storage. If designed to combine with a lost
lazarette and sugar scoop bathing platform it would actually require only a little extra length anyway.
I'd go for the new reversible electric
type. So much safer to power out. Electric
is a lot less effort of course. My electric winches have been pretty reliable and I think they are in general, so going electric is another area for the KISS principle to be compromised. You will be an old crock before you sell this boat and so you are building for your dotage probably. I'd go for powered furlers too unless you can make your winches work double easily. If furlers are electric rather than hydraulic saves having an hydraulic power pack and deck clutter with lines.
I'd make it fixed and insulated as sunbrella lets a lot of heat through and cover it in flexible lightweight solar panels
with a couple of windows to see the sails
. Also panels
on the deckhouse. I'd put tracks down the side to put side covers down to give a totally dry cockpit
for wet passages or for when it is really rainy. In the tropics nearly every boat has a bimini
and keep them up all the time, so why not make it permanent to start with. I'd make it hurricane
proof. Having solar panels
here should mean you don't need an arch.
I.e. minimum through hulls. Just seems sensible.
You obviously like it as you are going for a second one. Aluminium has high emissivity - don't you feel the heat inside on a hot sunny day?
Having been shut out of quite a few shallow spots this is something that appeals to me. It would occasionaly be great to get right up to the shore. Twin spade rudders for redundancy and efficiency appeals too.
I have lost a few bits of kit due to seawater ingress. Worth fitting seals
, but I can't see any dorades on the pictures. How do you get fresh air in at sea? I can understand removing dorades as they will block the view, but you still need to get air inside.
Mostly are good. There is the book as Jedi mentions. A ton on his website too. I'd copy a lot. A few above are promoted by him, but there are many others like putting the fridge keel cooler
in a fresh water tank
chamber. DC air con water pumps for each compressor
. External shading for all windows. Oil change equipment
To help with the KISS process: I recently installed a frigoboat fridge evaporator with is a freezer
chamber with a lid. With it I have a fridge and a small freezer
combined. Works really well for ice, ice cream and the odd fish
filleted and I don't bother turning on the freezer now.
This is against your KISS principle. I'd vote electric, but you do need to concede on the genset first. Anyway, with the space and weight with the tanks you can house a genset, improve safety
on board and reduce hassle in not hunting down or decanting propane
There you go, my 2 pence worth.
