I started construction today on the TMS-20 trimaran. I’m building the strong back this weekend. The strong back is the foundation for the mold. I used 3/4 inch CDX plywood made it 12 inched wide and 6.25 inches deep by 22 feet long. I’ll finish the strong back later today after I get some sleep and the beers wear off. I need to put butt blocks on the seams for the side and build legs.

If I mark off the cleats, 1-foot spacing, I'll call that good for this weekend. The stations are going to be 1/2-inch plywood. I’m making a female mold for foam strip planking cove and bead on the edges. If all goes well I'll try to have all the stations (19) cut out by next weekend. I'll post some pictures later today on the website.
