My opinion.

Osb can move if outside or if too thin. If you are outside building; use something like exterior ply 3/4" or if inside 3/4" material is more stable from movement. I used pressboard for my larger build.

Avoid 1/2" as it might move across the boats width.

What color do you plan to paint? Where will she sail? If you are in Dubai and going dark colors or in a warm place and going dark colors. You want corecell M and you will need to postcure prior to paint. Personally I would go corecell M in any hot climate.

This boat has some photos on this site. It was professionally built in Turkey and was stunning.

I'd build here with a diesel engine as an inboard. The foam and buoyancy foams make this boat unsinkable; so even a major problem won't render her unsafe.

I own the plans, but decided to build a catamaran instead.

Daer Fallguy1000,
Great thx for your advises and replies.
In fact the boat will be built inside and will swim at Turkey Eagean sea.
The color i think is the color which is shown as demo on boatbuildercentral webpage.
This will be my second built attempt as an ametour.First was a 5mt offshore fishing boat from Nathaniel marine and built as strip planking method.It was a big mistake for me because was so hard for first time builder.Here is a pictur of my cx457
Any comments and advises are welcome in my journey.Again very thx.

How about finding out what foams are available in your area and then asking the designer if they will work. Same thing for the resin. And welcome to the fun

Dear Fuzz,
Thx for your response.I am in checking foams isue and seen that Dininycell etc are not so popular in our market.Is that possible to use XPS or EPS instead of it?
For resin,i have used local epoxy resin for my first project.I think it will work.Rest of them like branded as westsytems etc are extremely expensive.

I do not know enough about the different foams to give you a good answer. I hope Jacques will see this tomorrow and give you the answer. If he does not answer do not be afraid to post the question again. Sometimes he misses a question. And right now he is healing up from a bad fall.

Ok very thx.

Xps and eps are NOT acceptable!!!

No. No. No. the boat will fall apart!!!

H40 is very light foam. I doubt the plans specify such light foam with low shear strength and lower compressive strength.

Corecell M80, divinycel H80, or other pvc/similar foams at 80kg/m^3 are acceptable. The transom might be specified higher; see the plans.
