Heat Treating???
Well back in the old days there was this ol man who buildt many a 62 fter in his back yard on the Chesepeake Bay. All his hulls are fair and hand nibbed using a rose torch and nibbing bars. Most sleek steel hulls you have ever seen. The full keel curved to meet the fairest hull not a square exposed weld on the hull. Seemed it was a hobby and he buildt 6-7 of em. I used truckbed liner as non-skid. When exposed to hard traffic and UV it becomes polished and slippery and needs re-coating in 3 yrs. I like the stuff but it's expensive Like 400 for me do do a small path and spot near the masts. I used Duraback(sp??) brand name. MIL Spec approved non-skid now. On a new build inside any good epoxy is great if properly applied! I do not like epoxy that is exposed to UV. It is stronger and more chip resistant but fades , streaks and needs to be re-coated more often than a good oil base. I use epoxy as a barrier under the antifoulant. If I had a new bare hull Id met-coat the whole thing inside and out. Thats spraying a molten hot zinc on. Thats how they coat the offshore platforms before painting. It's the very best for steel.

Most sleek steel hulls you have ever seen. Sleeker than Navy destroyers? I used truckbed liner as non-skid.

I used Duraback(sp??) brand name. MIL Spec approved non-skid now. Sounds expensive. I spent far less than that on the whole of our new deck, which is fiberglass cloth & LPU. ... On a new build inside any good epoxy is great if properly applied! I do not like epoxy that is exposed to UV. It is stronger and more chip resistant but fades , streaks and needs to be re-coated more often than a good oil base. Yes you're right, epoxy does not stand up to UV very well. OTOH you can paint over it with almost everything. ... If I had a new bare hull Id met-coat the whole thing inside and out. Thats spraying a molten hot zinc on. Thats how they coat the offshore platforms before painting. It's the very best for steel. Sounds like hot galvanizing. Why not just electroplate it with zinc, or build it out of zinc in the first place? I bet you will say "Zinc is not as strong as steel" but it would be if you made it thicker... it would be heavier but so what, if you wanted a light weight boat you wouldn't have it made of steel in the first place.

DSK Doug, I'm not an engineer, I just saw what people who could afford to do it right did. And I saw it endure harsh abuse in an extreme salt water application. Many steel shrimpers now met coat. You can beat the snot out of met coat with a 10lb sledge and never cause a rust streak. Joe |
