I have a 42 gallon poly tank in the v-berth of my 30'er. I would like more water storage
, as we will be doing longer coastal cruising this summer. The current
tank is set up wit ha deck
fill, and a water
pump, small accumulator tank, which feeds the pressure system.
I don't have much room for another solid tank. So, i am considering adding a flexible bladder tank in the bilge
area, under the cabin sole
. The boat as an inner hull
liner, which forms the cabin sole
floor. The soace in between this flat floor and the actaully v-shaped hull
, is the bilge
area. It is at least large enough for a 40 gallon tank. Of course, if this badder was full of water, and I then had a large leak from my v-berth tank, or from outside, the large bilge would not be available, and the water may flood above the cabin
If I decide to put one in, I would likely change the pressure pump from the higher v-berth tank to the lower flexible one, and then have the v-berth tank drain into the flexible one. (possibly adding a manual shut off valve on the upper one).
I would pad the flexible tank with foam, or something similar. However, it should not move much as the bilge has a deep v, so it should stay in the bottom v, even on a heel.
I only have a inspection
hole in the cabin
sole to access the bilge, so I can't put a soild tank down there.
I would like to have any advice on this setup, or a better way!!
