When I replaced the horizontal board 10-15yrs ago I used oak, but the original
wood that broke on me was a dark wood.
Does anyone know if it was teak or mahogany or what?
I guess I could use oak again since it will have less opportunity to bend with
the middle support I"m putting in.
Dennis, I like the idea of glassing the board instead of just epoxy paint, but
won't that be difficult to measure the board thickness? How thick is a wrap of
matt and epoxy?

White oak is, red oak, not so much.

Maple is not very rot resistant, but oak is.
There is a reason why oak was the material of choice for ship building.

Subject: Stus-List C&C 30 mast step yet again
Got the engine running, so I could shift the mast over to work on the step.
(BTW trouble was in the battery cables; corrosion inside the sheathing).
I have only two supports and the oak plank I used bowed in the middle; probably
because I didn't seal the edges well enough and water wicked in. It did last
10-15yrs though. So based on what a lister mentioned, I'm going to put in a
third support in the middle. I can only buy 3/4 marine plywood by 4x8 sheet.
So I'm going with solid wood for the support. The hardwoods dealer suggested
mahogany, but it seems to porous for a bilge. A friend suggested ipe (epay or
ironwood). Extremely dense and used in lock gates on the river. He claimed
that some don't even treat it.
I'm using maple (very dense) instead of the oak I used last time for the
horizontal plank; oak apparently is known to bend readily with moisture,
especially steam.
I'm planning to coat all with a few coats of epoxy which I think Dennis
suggested; the hardwoods dealer suggested marine poly.
So, given I'm going with wood instead of a wood/metal combination, are there
any suggestions about which wood and the coating?
