I would put it way ahead of cedar strips. (But I still like working with Cedar - wood is nice)
I find 10mm foam nice and easy to work with. Vertical strips about 300mm wide are easy to bend.
If I am going with corecell, I will make my own bead 'n cove with 12mm foam. I am not a big fan of the vertical strip method because of all the screwing needed to keep the foam in place(female mold). Now I'm wondering if i can use a male mold(plug) with the vertical strip method... Hmmmm? This may tip the ballance on the side of foam
Although Cedar is somewhat heavier, it's unbelievable how much the cedar adds to the overall strength and rigidity of a hull!! I need this thing to be able to sail offshore. I have worked with corecell and a few other foams before and like them well enough but i am really tending to go with cedar
A550-12mm CORECELL can be had in 4' x 8' sheets @ ~$5/square foot
What is cedar worth these days >?
BTW: Corecell can be heat-formed very well.
