Hello, I recently bought a 37/40 with a tiny, smelly bladder holding tank located under the vanity in the head. That can't be the factory solution. At the moment the only options I can see for adding a rigid tank are the v berth area, which would require parallel hose runs for fill and discharge along the port side beneath the settee and through the hanging locker on that side, or aft under the shower pan through the aft cabin furniture to the port side cockpit locker. The v berth location would gain me up to forty gallons but require over forty feet of hose run. The aft locker location is a much shorter run but might only get me ten or fifteen gallons (has to clear the manual bilge pump handle). Neither seems like it would satisfy a typical factory installation requirement. What do other owners have?

You're prob'ly thinking you're limited to off-the-shelf rectangular tanks...not true.
Ronco Plastics makes TOP quality thick-walled (50% thicker than most other mfrs) water and waste tanks for a very reasonable price and have more than 400 shapes and sizes, over 100 of which are non-rectangular, and they install fittings--including diptubes--in the sizes and locations specified by the customer when they make the tank. There are retailers who sell Ronco tanks, but Ronco sells direct for a much lower price...and they're great to work with.
When looking at drawings it's important to know that there is no top or bottom until the fittings go in, and YOU decide where they go. So rotate, flip in any orientation to find the tank that fit your space.

I'll be glad to help you select the best fittings locations and sizes for the tank you select.

FWIW, I decided the aft locker location was a no go. It would have only given me about 10 gal capacity and none of the Ronco standard tanks would have worked due to hull curvature so, in addition to being puny in capacity, would have meant an expensive custom tank. So, went with 20 gal standard one up under the V berth, much as I hated to do that. Hose runs were pretty far and an electric pump for overboard discharge offshore back through the original through hull was required. Overly complicated but I still can't imagine another solution that would have been standard from the manufacturer.
