What type of wood on 90 Walkaround?

[bsterling]

I have a 1990 23' Parker Walkaround and the 1/4" plywood on each side of the cabin besides the seats have rotted and needs replacing? Does anyone know what type of wood this is? Mahogany maybe? The thicker 1x framing is solid but needs to be sanded and finished, as does the rest of the trim and the doors to the cuddy cabin. What is best to use to seal this with?
