Not to hyjack other thread.

So called "two step" (sanded prior to phonelic faces being applied and it's all fir)in 1/2" for Seal or Mara strakes.
Why not? It's made right here in Richmond and it's only $40CA.

Its what I plan to use. It is meant for outdoor signs that won't get the same level of care that a boat does and it seems to be of higher quality than the marine fir available here.

Cut a few pieces and...

boil it
bake it
freeze it
Do the above in rapid order. From boiling to oven to freezer. Or any order that suits you.
painted (seal all the edges) and unpainted (raw edges)
stick a piece in the composte pile for a few months
a piece in the diswasher for a few months

Make up some test joints where you are gluing the two resin coated surfaces together. Break the joints. You may find that you have to plane/sand the resin off to bare wood to make a strong joint at the laps and stem/keel/stern surfaces.

If it survives, build with it.

ps: I found a commercial sign makers discussion group today. Everyone who used 2 sided Olympic Panel Signal MDO praised it. They are in Washington State somewhere.

pps: Gert, you owe me a sail in your boat someday. :D If I build, I may be up your way looking to score some nice Alaska yellow cedar. Keep your eyes open for some of the good stuff.

Interior voids are something to watch for.
I microwaved a piece of twelve-year-old(it ain't like Scotch)one-sided MDO highway sign.The last two years it was lying on the ground.
In boiling water for five minutes,the stuff survived admirably,even though there were patches of rot where moisture had penetrated from the primer-only back side.

My supplier asked me what I needed so much MDO for; when I told him, he said he wouldn't sell it to me!

Interesting. What does he know that others who have used it for boatbuilding don't know? Maybe MDO isn't the correct choice for an affordable alternative to European or Asian marine plywood.

Gert, you know what? You really should go visit Paul Gartside and come up with a design that makes the best use of your readily available local materials. Alaska yellow cedar, western red cedar, Douglas-fir, Gerry oak and black locust. Heavy on the yellow cedar. :D Either a clinker, cold molded or strip plank + cold molded veneer hull.

OR, buy the plans for Eun Mara from Iain and cold mold the hull. Once in the water, you will never know what the hull looks like.

Can you tell me, based on this picture, the type of hull construction used?

I just checked Westwind Hardwood's prices for marine plywood. How much cedar and fir can you buy for $2,500 CDN? :confused:

I here ya Vencha; I seriously dought I can afford a navel architect. I love the lapstrake look and I'm comfortable with plywood. This boats gonna live on a trailer (read: dry) Is western red cedar a suitable material for lapstrake and living/traveling on a trailer? I dont want to strip or cold mould. If I did I'd buy a glass boat! I saw the artical in Water Craft were they cold moulded the Mara; she didn't look neer as good.

First of all, Paul doesn't cost near as much as you may think for a small boat.

Paul built SKYLARK and she lives on a trailer. I'm the wrong person to ask about clinker hulls, trailiers and your part of the world. You need to talk to folks up there who have had some experience.

Good luck!

The original Simmon's Sea Skiff that I rebuilt had MDO panels on it's bottom. I ended up replacing them with Bruynzeel, but believe the only reason that the MDO had problems was because the boat had been neglected and allowed to sit on the trailer collecting rainwater for months at a time. MDO certainly finishes-up a heck of a lot nicer than fir ply does.

The MDO guy said it some of it may delam; it's a question of quality control; how sad. We practicaly owned the plywood industry once, now we're constantly griping about about the trade deficit and here we are with only ONE plywood mill left in BC. If ya cant compete with a cheaper product make a better product!
