i think the thickness of the eps boards is what will be needed to be worked out(for the hulls anyway)i think a 7 footer can go down to 2.5 inches which along with that glassing schedule should be a decent flotation/flex/weight ratio.
I tried to post an image on another thread, but it didn’t seem to go. I’ll try again here. These are the boards we made for me. We made a lot more for my brother.
i’d like to see people post pics of their hulls - pics were you can appreciate the features, if thats possible. Was thinking perhaps starting a new thread, but then probably given the numbers of peeps that ride them, better just to keep it here.
i keep pickin up that dam TSJ article on em - am i hooked without even having ridden or seen one in the flesh?
so if you gottem, pleez postem.
Latest observations on the hull:
Just spent last Thursday through Monday at Las Gaviotas Mexico. It’s a rock reef with longer rights and a short steep left. There was a solid head high swell the entire time and pretty clean conditions. It took me a few sessions to get the fin dialed in. I ended up moving it forward from the center of the box to about 2" from the front of the fin box. This seems to be the magic spot on this board for that particular wave. After that, the board was on fire! You could almost feel the fin flex and release off the bottom turns and just slingshot up under the lip. From there, the trim speed would steadily increase. I found the optimum foot placement, when trimming out, was with my front foot just behind the deck laminate. This worked front and backside. The most difficult move was a frontside carve. You really have to push hard with both feet and get that board up on the rail to pull it off. Speed is also a huge factor. When you see a flat section of shoulder ahead, try to build as much speed as you can and then power push that baby over onto the rail. If it’s done right, you can come out of the turn at Mach2. If done wrong, you’ll do the kook slap on your back with you @ss in the air…or get launched over your board. Believe me, I’ve done both…plenty of times 
I had a lot of compliments on the board during this trip. It’s funny how not one single person knew what a displacement hull was. However, everyone that checked out the board really liked it and wanted to learn more. It’s a great conversation starter.
