My 72' glasspar 16' tri hull uses foam foam for most of its strength. with only two wood stringers laying horizontally, bow to stern, laying on top of the foam no cross ribs. the wood is glassed in to the bottom of the hull creating a drain channel.
My plan is to eventually put a mahogany...
I was wondering if anyone knows the difference between the two manifolds that go on the 120. I know the larger one will also fit the 140's. But is one better than the other? Do they interchange on the head? I've got both available for my project, and I want to do this right. Also is it worth it...
