Side Planking, Tunnel Sides, Decking & Cowl.

Postby weasel » Sun Jan 10, 2016 3:37 pm

I am making this Tunnel might and I have had a few questions answered by some of the builders on here. It's great help!

I can't get 1/8" marine plywood around here. I don't see a problem with making these parts (Tunnel sides, Side planking, Decking & Cowls) out of 1/4" Marine plywood? It will just make the boat a touch heavier correct?

You didn't tell us where around here is. Please add your location to your profile.

I did a little profile update now.

I have been asking a lot of questions on here, because I am a greenhorn boat builder and do need some insight :lol: .

Welcome Weasel - Ask away; lots of greenhorns here and I have learned more from answers to other people's questions than my own. If it's been answered before, someone will usually post a link to that thread.

I could be wrong here and if I am, I apologize now. But I believe that 1/4 thick plywood would work. The plans call for 1/8 ply because it's a race boat and so, it's designed to keep weight to a minimum. There would be a certain trade-off in that a boat built of 1/4 ply would be tougher and stronger but it would also be heavier. Heavy is not so good on a tunnel hull. It needs to be kept light so that it can get up and ride on that cushion of air that a tunnel hull is supposed to ride on.

5 mm will work also. Try World Panel

I checked out "World Panel" it looks like a good place, but I live in Minnesota hmmm. 1/4" plywood is 6mm opposed to 5mm. The weight issue is only a few pounds for the wood I assume. If you have a 200lb guy driving 1/8 inch plywood, or a 180lb guy driving 1/4" plywood, isn't it the same weight on/in the boat?

Ok, Yeah...

But if you've got a 200 lbs guy driving a 1/4" plywood boat, he's not going to win the race. :shock:


But hey!! He'll still have fun! :lol:
