I would say that, while genuine teak & holly soles are shipshape when in proper condition, they are problematic. They need refinishing frequently, replacing occassionally, and are prone to deep dings. Many new boats have gotten away from installing the stuff on newer models; all
J/Boats, Farr 395 (& likely other Carroll Marine boats. They install a formica-type, or pergo-like flooring that is actually pretty tough to tell that its not teak & holly if you are standing there looking at it. I would guess this stuff is either more hardy (with the underlying board soaked in epoxy)and pretty cheap compared to genuine T&H.
