marine plywood for seats?

[jvcobra]

I need to make new seats for my 79 eluder since the old wood became rotted. Do I use marine plywood or regular wood with a resin coating? What do new boat builders do?


Thank you,
Joe

Do it right with marine plywood. http://checkmate-boats.com/6/ws/,s,8626072361/Graemlins/thumb.gif

Either way ya go resin coat the wood. http://www.checkmate-boats.com/infopop/emoticons/icon_wink.gif

What I have found is this.
Use standard interior grade ply wood. I used 3/4" for anything that carries weight. Seal with resin.
What I found about the marine grade is 1, more $$ and 2 it has a high moisture content. Resin does not seem to bond to it as well.
Also before you lay on the resin, sand the wood down with 80 grid. This will rough up the wood, lets the resin have a mechanical bond and well as chimical.

Up here in Canook land....

I buy Fir good one side plywood. The use marine glue to put the "plys" together. http://www.checkmate-boats.com/infopop/emoticons/icon_wink.gif

Use fir good one side. The only difference is that on marine grade, every layer is good. This means they remove the knots and splice in good wood on all 5-7 layers. You pay alot more money for this. Thin your resin down to get good penetration into the wood, and make sure you coat all sides and edges. Most boats are built extra strong(wood is thicker than required)wood structures anyway. The only time I would use marine grade plywood is if I were making a race boat(i.e. wood tunnel hull)

I used marine on my rebuild. Just wanted to be safe. http://checkmate-boats.com/graemlins/welcome.gifCOBRA!!

starboard is another option.. it handles just like wood, its a lil pricy, but will never rot..

What is Starboard? I have seen it advertised, but not sure what it is... synthetic wood?

I guess the best way to describe it.. is its plastic. It works similar to wood, it can be sanded, it does cut a bit different especially when using a jig saw.. and you can staple to it also.

I just replaced the engine hatch, and back seat in my brothers boat with it.. (we've done it before) so this should be the last time.

Thanks for the information...

I need to replace the plywood for the back of my bench seat (rotted only at the top under the vinyl trim, but I want to take care of it before it gets worse)..Starboard sounds like a good bet. I will price it before I decide vs. marine plywood.

Does Starboard need to be sealed where you cut it? I guess I am imagining plastic with a foam-like core which gets exposed when cut and should be sealed.. or is it solid?

The product is called King StarBoard it is solid and if you can make things out of wood, then you can make them out of StarBoard. Check out the website at: http://www.kingstarboard.com/Default2.aspx

Starboard is a high density pvc coring material that is excellent for seat frames and combing panels. I used it to rebuild my rear bench seat box on my old Spectra 170. It comes in various thicknesses also!!
