You are referring to what Whaler called "Ceiling boards". i have no idea where that designation came from, but properly installed and re-varnished, they are one of the beautiful features of these boats!

Anyway, they are 3/8" thick Phillipine Mahogany, not teak, and in most boats they need to be completely taken apart, stripped of the original urethane coating, and sanded to bare wood, re-varnished 6 coats, and re-installed with #8 screws. It is a LOT of time consuming work! In the earlier boats, they were one piece, as long as 16'. In the later boats Whaler installed them in two halves, allowing easier installation of saddle tanks which the boards did not go behind.

This was one of the bad installation details on the boat, probably done to save costs. They are fastened to the teak vertical wood blocks with bronze ring nails, which always fail causing the boards to rattle continuously.

To properly repair, you have not only remove the boards, but also the vertical blocking. The old stripped out nail holes in the blocks will not hold screws, so they have to be drilled out 3/8" diameter, and teak pegged. Then re-drill for the screws. If the nail heads have damaged the mahogany, they also have to be drilled out and pegged, then re-drilled. Wherever there was a nail, replace with a screw.

In another post I gave you a link to some photos of mine. There is a photo showing these ceiling boards completely redone.
