Custom holding tank

[Jamie 10017]

Who makes a goog custom plastic holding tank? I am restoring a 87 Wellcraft Gran Sport and the P.O. had a 13 gallon tank stuck in a compartment standing on it edge (not the side) but on the corner. Doing a little research I have found most of these boats came equipped with a 20 or so gal tank. I cant find a picture or measurement of the orginal tank set up so I thinking of a custome made tank.But I have a few questions... What is the best method to secure the tank down? How is your tank supported does it sit on the hull? or in a framed support? Any ideas or thoughts would be a great help. Also what about vent lines, I was thinking of 2 3/4 vent lines one on each side of the boat...what do you think? I know air into the tank is imporant. I have a Raritan Sea Era head and it uses raw water I am considering the system that Raritan has to inject there cemical into the line at each flush...ok enough of that any ideas or comments.... Thank you to all Im new to the fourm and I really like it Jamie
