Flooring thickness

Recommended Posts

Getting ready to replace the floor in my 1989 sea nymph wanted to know if anyone knows the original floor thickness? It was replaced at one point and the walkthrough windshields to not line up properly. Thanks for any help in advance.

Most boats that are 20 feet or less used 1/2 inch plywood. When you remove the old floor , you should be able to see what is there. If  you use thicker plywood , make sure your side panels still fit.

Most floors are 1/2” I believe. They started with a full aluminum construction in ‘93. Keep us updated with info and pics. I’m redoing my ‘90 this coming winter.

 I rebuilt a 1984 sea-nymph center console CC-171. The floor I removed was 5/8" 9 ply marine plywood. I replaced the floor (sole) with 7ply 1/2" marine plywood. finished with 2 coats of interlux 2000e epoxy primer and 2 coats west system primer plus awlgrip. and........ its a little more flexible than I'd like.  I'd definitley use 3/4 9 ply if I were you.

Most of the councils were aluminum and when not screwed down flex all over the place. If yours are you will have to remove the windshield to square up the council boxes again. Not that big of a deal to do, just takes some time. 

With an aluminum boat I would consider aluminum for the floor.

1/2" marine flooring as noted above (and above).  I've replaced an entire floor section on a previous boat I purchased.  Was able to install new rivets which had some leakers and also apply Gluvit on all of the others.

Sea Nymphs of the 1980's were a plywood floor.
