I'm too lazy to look up the specs on your boat, but I have a 20 gallon water tank in my V-berth and that's plenty of weight, if you catch my drift. In other words: your current
tank is what's acceptable in your V-berth
How much water do you need?
If your cruise
includes a 30-day (if all goes well, 40 days max) ocean crossing
, and there's 2 people on board, you'll need around 50 gal (you'll need 2,5L/0.66 gal per day per person min.).
Before you turn your boat into a (barely) floating watertank: look at your plans. Where there's humans, there's water, so you won't usually need to carry water for weeks and weeks on end.
With your current
tank you're good for a week at least. How often will you be at sea for longer then a week? Is that worth building (an) extra tank(s) or can you use cans for those times?
If you feel you need extra tanks
, consider the weight - you don't want to add too much (and you're also bringing fuel
, most people buy enough food
for a zombie apocalypse - it all adds a LOT of weight) and you'll want to make sure they weight gets distributed correctly (using cans instead of a tank helps with that too). Don't forget thinks like the battery
bank when considering where you can add weight.
