Did I not read somewhere about fabricating one's own fiberglass tanks? I cannot locate it here on HOW or any of my other haunts. It's decision time, the bladder tank is in the dumpster. And yes, I cleaned it out first! 
I spent time on two different Saturdays cutting cardboard and making templates to the various sizes and shapes of Ronco tanks. A couple of the 20 gal. ones fit nicely in the center v-berth. But they make it difficult to access the log and depth thru-hulls and I don't think that is a good idea. And the long hose runs would persist. And I lose a nice storage area. So I think that I want to build in a custom tank. Is this nuts? Like I don't have enough projects. I have a sketch that I wanted to post but have not been able to get anything on the Photo Forum. The idea is to glass in the starboard v-berth locker. It's forward end is the back end of the large center locker. That bulkhead at the back of the center v-berth is structural, goes all the way across the boat. But I thought I could cut a few three or four inch holes and turn it into a baffle. Then I would glass in the entire starboard side of the center locker adding at least 16 gallons to the size(come in about 18" from hull and straight down). It would require two tops with cleanouts, one in each locker. The aft end of the tank in the starboard locker would be just forward of a capped thru-hull. It was originally for pumping overboard, a no-no in Lake Erie. But it would be available for a someday trip offshore. This would give me about 30 gals., provide for very short hoses, all with good access. What do you think? And where do I find the info for making the tank foolproof(bad choice of terms)? Thanks for your help.
