FibreGlass Holding tank?

[SeaPuppet]

One more point

... I forgot to add. One of my important design considerations is to minimize making any cuts or other mods to the boat itself. Nearly all of the work done in the plan I just outlined is done OUTSIDE the boat, and mistakes made there can be easily corrected. The final step of reassembly of the tank halves in the boat may be a little messy, but that is why I spent so much time thinking about the joint itself.Please -- shoot holes in my plan! (BEFORE I start!!)

Why do you resist improving the original boat?

The bane of most owners is the lack of access to tanks and system components. Builders don't put hatches in ONLY because hatches add to the cost. That shouldn't stop you from doing it and/or doing whatever it takes to provide total immediate access to everything on your boat. You won't be taking anything away from the boat, you'll be improving it.

Wow!

do you write instruction manuals for a living ?Sounds like a plan. I guess the only problums I can envision is having working room trying to get a good glass job putting the two halves togather, while upside down breathing.  Buy a good quality charcoal resporator. And make sure you can reach every where inside as well, easily!, through your inspection port. It's hard enough to glass with one hand as it is.If you are this organized on paper you will get it done I have no doubt.Post some pictures as you progressEdit: Peggy brings up a wonderfull point! Wish I had a few more.

But why not get a poly tank?

Mike:I am wondering why you don't just get a poly tank to replace the old alum. one? They last for a long time and are not very expensive. Ronco has many tanks available and will put the fittings wherever you need them too. These tanks are seamless and will probably provide you with a good product from a proven company.

I'm sober and I think that if you build a tank

you should ba able to pressure test it before you install it and that you should be able to remove it in one piece at a future date. It is your boat you don't have to ask permission to cut holes in it to gain access to the innards. My boat was built without a liner (for which I am eternally grateful) so I have access to every square foot of the inside of the hull and to every installed component.

Combined tanks?

He wants a tank too large to fit down the hatch, I believe... I find it perfectly acceptable to set a constraint that "i don't want to enlarge this hatch", as he's willing to accept the fact that he may need to make the tank smaller and/or in two pieces. How much access is there ,once the hatch is inside of this void? Perhaps you could use two smaller tanks connected top-bottom with a large 6" piece of rubber hose and some big hose clamps?
