Just found your thread here. Great project you've got going. Before restoring a Tiki 21 and beginning my current Tiki 26 build, I built a Hitia 17 back in 1998. It's a great beach cruiser and was surprisingly fast. I made a hard deck in two sections for the trampoline area between the mast and aft beams, which made it drier and provided space for a tent. I put a tramp in the forward area between the mast and front beams, which served as a "front porch" for the tent. I used a basic trailer frame and designed two removable beams with rollers mounted that I could quickly attach at the ramp. The hulls were then moved out by lifting one end, then the other out to the cradles on the long beams. I got the process down to 45 minutes from arrival to launch, making it feasible to daysail off the trailer, but mostly I went out camping for several days at a time when I used the boat.
