Both my Marinettes used mahogany. I removed the trim so that I could work flat on sawhorses, stripped it with stripease, bleached with Clorox, sanded, filled, and varnished with Epiphane Bootlak. Put it all back in. Looks nice.
Newer boats than my '75 might have teak. The routine would be about the same.
