All modern ocean going ships are made of steel. He needs to make the sides high enough (create hollow space) to allow for the displacement weight of the steel

Fastest on water? Hydrofoils... Loads of engineering though

Even full size ferries can rock it though

Extremely efficient as it cuts right thru waves, could be a really good project, single man, solar, speed thing cutting thru the water heck yea.

Looking to restore a 1976 Glastron trihul boat, are there any good places to look used rails and windshield parts?

If you are adding fluid to top up a system that already has fluid in it, it's important to use the same fluid. Different power trim systems use different fluids- as example, over the years Mercury has used trim systems that used power trim fluid or ATF, power steering fluid (almost the same, and can be mixed) and some older systems used SAE30 engine oil. Before adding any fluid, find out what is already in it. If you are unsure what the existing fluid is, give the year and model of your engine, and I'll tell you what the recommended fluid is.
