Kurt's description of the 23' daysailor trimaran update is here:
I finally got the first run of modeling the updated 23 daysail trimaran. Version B will have ama rudders and the even hotter version C will have foils. It is a developed plywood/epoxy unit with core vacuum bagged onto the flat surfaces needing that. And carbon fiber where it helps. At around 360 kg lightship weight, it can be built for around $5000 us in construction materials. The connecting beams should be carbon mast sections. The camper version comes next.
