Flexible Water Tank?
On my '98 35 ft Beneteau the PO put in a bow thruster which I love when I am docking. But it was installed in what had been the forward water tank. Now we are down to 50% of original fresh water storage and the boat rides light in the bow. The orignal deck fitting for the forward water tank is still there. Likewise the filler hose and overflow which have been cut off about 2 ft below deck and sealed with wooden plugs and glue. The original fresh water supply from the forward tank to the manifold is still there also, but sealed.
Question #1: would it be advisable to install a flexible water tank of some sort in the 1ft X 1.5ft X 5ft empty cavity remaining aft of the thruster tunnel and reconnect it to the original hoses?
Question #2: if yes, what make/brand/type of flexible tank would be best for this application, and what precautions should be taken?
Thanks for any advice you can give.
