flexible water tank

[blackbeard]

Currently mine resides in a rather small under-bunk locker which seriously restricts the amount of water I can get in it (and also leaves it reluctant to drain completely).

To improve (slightly) the situation I can either:
a. move it to a slightly larger under-bunk locker, thus losing the use of a rather handy space to put kit; or
b. use the space originally intended, by designer/boatbuilder, for the tank. This would give roughly the same volume as the larger under-bunk locker, but the space is sentry-box shaped rather than coffin-shaped and I wonder if that might give problems? (it certainly did for the initial installation which didn't make best use of the tank provided. Not the best installation maybe). Also, I would need a made-to-measure tank which would cost a bit more.

There's plenty of space in the forepeak locker but it might give problems in restraining the tank from moving, in piercing a watertight bulkhead and in having so much weight forwards, so I'm a bit reluctant to go that way.

First Mate has commanded that we carry more water.

Any views/ideas?

Could you build in a water tank using GRP? That would use any space efficiently and generally means less work constructing one that fits a space perfectly.

If the existing flexy tank is not ventilated, you can suck out the last drop.

Could you retain the existing tank and add another (maybe smaller than full locker size) in one of the other lockers? In parallel with a 'manifold' or in series?

A triangular flexible tank under the forward V berths is certainly feasible. Pad any potential abrasion points and use the eyelets on the tank to hold it in place. You may also need some form of restraint to stop it from pushing the locker top upwards when full, or you can screw the tops down. If you are interested I have a brand new Plastimo 115l triangular tank surplus to requirements (I managed to repair the original tank).
