G,Day. I have purchased the plans for a longboard. A mate of mine. Is building it as I have another project to finish. my question is, can the frame be skinned with marine ply? Solid timbers for the rails nose and stern but ply for the deck and/or hull.

Hello, Yes it can be skinned with plywood. I have used thin luan plywood to skin a few boards but there were a couple issues that I didn't like about it. 1. the plywood was very thin and had a lot of flex, I would recommend filling it with foam to stiffen it up. 2. If there are any wobbles in the deck they cant really be sanded out without sanding through the thin first layer, creating a patchy deck. 3. Feathering the skin into the rails also sands through the plys, which leaves wobbly multicolored lines around the perimeter of the board. They can be masked by covering the board in a dark water-based stain, or by adding a thick pin ine around the board. But if you don't mind these things, go for it!!

Number 1 rule: Fill it BEFORE adding the top skin! If you fill it after it is assembled, it will blow seams and push bumps up on the deck!
You can use spray foam and fill each cavity entirely, then remove excess foam with a hand saw laying across each rib. But it is easier to buy a sheet of foam and cut a block out for each cavity, then fill the perimeter and top of each block with spray foam, then shave off the excess foam.

Chad, Thanks so much for the response. I just ordered the plans for the SUP. I'm pretty psyched. I've been researching this project for a while, but it's my first one. When you say it will take a first timer a month and it only takes you a week, is that a 40 hour week? -TWD

Well, I can usually build and shape it in a week, taking my time, there is a lot of down time waiting for glue to dry or wood to soak. it takes me a long time to glass though, specially if i use epoxy as it kicks off slow.
