For what its worth, having a pressure water
system on a 26-27 foot boat is perhaps going overboard
. Do you really need pressure water
? Squeezing a shower
in will be pretty difficult. For cooking
a pump faucet is plenty fine to my mind. Less complications, less to break down. Less power consumption
Stoves, I find a coleman camp stove works admirabley, at a fraction of the price
. I had a gas-fitter friend make up the required coupling to the stove and use a regular tank n regulator
for the feed.
I had a portapotty on the last boat, It broke a fitting at the bottom and leaked fluid all over the place. When I finally did get around to replacing it, I got one with a tank under it, that was plumbed for pump out. I forget the name of it but it served well on a 26ft boat. The tank was very small and a nuisance if you wanted to use it for more than a weekend but better than the original portapotty.
