I also have a '77 C30. Last year I refinished the cabin and chart table tops with teak veneer. I also re-formica'ed all counter tops. I did a search for "veneer" on the net and found a bunch of places near where I live. It was easy, a 4 x 8 sheet of teak veneer rolls up like a tube. Check on the net.
