I agree with Fallguy except for the mold thickness.
1/2" OSB is too thin but 12 mm ply will work. Thickness does not really matter as long as your mold is sturdy.
For foam, I am certain that I do not specify H40 for the hull but it is acceptable for the superstructure. I prefer H80 or equivalent everywhere.
Corecell and Airex are excellent foams, do not take short cuts with the foam.
Use a different foam for the transom, Airex has an excellent one.
I prefer diesel straight drive with the down angle transmission.
Check with your foam manufacturer for the resin. Here in the US, I like System Three Silver Tip. No wood-epoxy resin please but vinylester is OK.

Faith, Jacques will respond back to your questions later today. Regarding the DXF Files, we no longer sell the DXF Files, have not in about 10 years. They are strictly owned by the Designers. I will remove the mention of the DXF from the plans today. I sent you a separate email regarding the DXF Files. Sorry, Jeff

Pay close attention to the stations and transom mould. There has been some builder confusion on this issue before.

I do not know if this builder is still working on his LB26 but he has some good pictures of it.

Re: LB26 Questions from a newbie
About the molds: with a stiff material like plywood or cedar strips, 10 molds are sufficient but if you build with foam, you must use 20 molds. We do not want the foam to sag between molds.
