my advice for what it’s worth is make BOTH. And mould the bases out of epoxy and milled fibre. Yes , the wood flexes a bit …depending on how many layers of cloth and [what] resin .
fin making is fun !!
good on you Brian …any chance you could post a pic or two when they are done , please ?
cheers !

I’d look forward to hearing from you which you prefer too, once you’ve ridden the glass and the wood fins…
p.s. - nearly forgot …on this weekend just gone , I made a pair of foam core twin fins for my fish . Bases still need to be moulded…
Use 7 ply Baltic Birch. 3/8 or 1/4, once it’s foiled your going to cover it in a layer of 6 oz glass. I’ve got wood fins on my 9’6" gun, the’re plenty strong. I think the question is how you put them on. You don’t see many big guns with FCS plugs, mostly glass on. wood fins are stronger than the plastic composite FCS fins you get with a new board. But the strongest fins are glass. if you’ve never seen glass on fins before they are glassed on to a board, you’d be amazed how thin and sharp they are.
It’s all in how you foil them, how thin the tip, how much rake, how wide the base, etc. Take the time to get the design right…and you got to do 3 of them the same way, or your going to have an asymetrical board.
