Working on where to by the plywood today. Man, AA marine plywood is not cheap! But I think it's a good investment to go for the best. At least for the hull. The sea here tend to be pretty choppy. And I'll imagine the more experience plywood is easier to work with, i.e. less frustration and more fun.

In my search for boat related content, I stumbled over this video: https://www.youtube.com/watch?v=JXKRy33jHUw
About 1:30 in, you'll see he opens the hatch for the motor. I noticed the the latch and the hinges. The latch is like a door handle on an aston martin :D And the hinges are covered from spray water. Is there a place that sell these new?

I have another dumb question. Can I instead of using 4mm plywood for the hull, use 4mm pine cut into 4" strips? Any strength issues?

You can do that. It's the original way to do cold molded construction, and I believe the Van Dam boats are built that way. Typically, marine plywood is more convenient and lower cost per square foot but it's structurally acceptable to use thin boards. The installation is the same.

I don't know about the handle. I think Jenko made some of those hinges.

PeteG is correct about Van Dam using solid lumber to cold mold. They use alaskan yellow cedar for the inside layer and then switch to marine plywood for the intermediate layers. It makes for a beautiful interior.

I agree the hardware looks great. Wonder where it came from.

It seems that this type of hinges is called billet hinges.

Maybe a combination is the solution :)

Does someone have information of the total weight of the boat, and weight distribution?

Is that dash made out of glass fiber with veneer? Or is it possible to even get these shapes with a wooden frame?

I'm sure I've seen other construction pictures of this dash, showing it being constructed out of "stepped" wood laminates, like Lego, before being sanded to shape. Van Dam really continue wooden boat building into the 21st century. I love the classic shapes but modern designs like this show how you don't need to be plastic to be cutting edge!

Indeed they are cutting edge. And it seems they have made a good brand. Do you remember where you saw those pictures?

I have a question about screws. Is it okay to use stainless steel instead of silicon bronze under the waterline?

And I see some people use screews for the plywood in addition to epoxy. Is that necessary?

My understanding is that Stainless Steel will corrode if it is fully encapsulated, so you want Bronze wherever this will be the case. Also, the screws are mostly for holding the wood together while the epoxy sets up, but many like the added insurance that screws offer.

Fasteners are a big investment. I am using SB because of corrosion concerns, with the exception of the carriage bolts between frames and motor stringers (a significant savings and easily inspected).

So far, I have been able to find five screws with router bit and saw. In that respect, I much prefer SB.
