323 Water Tanks

[323Voyager]

During my survey I was warned the tanks were not usable for drinking water. Also the Bow tank was cracked and leaking. Doing some digging I couldn't find much info on replacing them. So I did what any untrained fool would do, and started cutting, I mean investigating...

The water tanks were made of fiberglass and were glassed to the hull. One under each Settee and one in the V Birth. I cut out the Settee tops. They were sandwich construction like a deck, and had 1/2" plywood core and glass on each side. The tanks were glass, and quite thick. It took awhile to cut and grind them out.

In the above images, believe it or not, I had cleaned them up with bleach. The insides were coated in black slime and smelled bad. The tanks had baffles, which would have made them near impossible to clean properly if not replacing them.

Here are the pics with the tanks almost entirely removed.

I measured the area available to me, and scoured the inter-webs for premade tanks that would kinda fit.

I designed how I wanted the ports on the tanks and ordered them. Next I will be making supports for the tanks I will glass and epoxy to the hull, for the tanks to rest and get strapped into.
I plan on making the tank "cradles" out of 1/4" marine ply and glue and stitching them together and maybe covering them in chop strand or just epoxy to make them water resistant.

The last pic is just the tank sitting in the space under the settee to make sure it was going to fit.

For anyone in the future looking to replace their 323 tanks. These are the ones I chose. I got them from Ronco Plastics.

The two Settee tanks are just a mirror of each other and are the B228, 30 gal Tanks.

The Waste Tank is B226 a 17 Gal tank. (This tank was also in the VBirth, not sure if I'm mounting in same place, or changing head layout and mounting in the head)

The Bow tank is B469 a 39 Gal tank. All fit quite well.
Below are the drawings I made for the tanks and their hose attachments.
