Construction Materials

Yeah, we mostly think of boats built out of Fiberglas/Aluminum/Steel,, and sometimes the more modern iterations of wood/epoxy.
All of the above have both strong and weak points,, no free lunch.
So, letting my mind wander; When I win the lottery I shall then be in a position to have a custom boat built, using whatever materials I wish.
If it's a BIG win, I'm not sure that anything could beat-out a boat made out of Titanium;

If it's a smaller win, the use of Copper-Nickel would be hard to beat;
https://www.copper.org/applications/...boat_hull.html
But, if you want to spend even less, you could use CDA 655 Silicon Bronze,, the "Old Man", Nat Herreshoff was using Bronze over a 100 years ago.
No rust, no corrosion, and no bottom paint ever needed.
Their are several high-class builders that can easily roll metal into complex compound curved shapes to make a nice and fair hull without resorting to a few tons of filler.
The Cu-Ni and Bronze would want paint above the WL, but I'm thinking that the Titanium would look just fine with its dull/satin color,, but you could buff it out.
Oh well,, sometimes it's nice to think "what if".

Re: Construction Materials

I've never heard of a bronze hull.

However, you might be interested in this old nugget:
"Copper-Nickel Boat Hulls: Performance and Corrosion"
https://www.copper.org/applications/...corrosion.html

And “Boat and Ship Hulls”, from the Copper Development Association
https://www.copper.org/applications/...cations/hulls/

Re: Construction Materials

Even with a big lottery win, you'd be better off having some fancy-shmancy carbon fibre / high tech aluminium / ice-proof steel / whatever and still have a budget for professional TLC every year. Gives you overall a better ship than building it out of some stuff nobody cares about.

Re: Construction Materials

With a hull built of those metals you'd have to worry about galvanic corrosion.

Which metals?

Al, Ti or Cu-Ni, Bronze?
