There are some other posts on one offs a little bit back and prob in the archives, but I'm not sure what the simplest and quickest would be. My initial inclination would be to build foam forms and thread them on a strongback like a stripper. And then, either glue foam between and proud of the forms OR glue netting or 1"x1" plastic web netting on the forms and spray foam into it. Then use long fairing board and sand down to the form ht.( Maybe different color?)

The reason for the forms is then you can tightly control the design. In your previous post you talked about 12" spacing, but this needs to be modified in order to design a close fit squirt. As in surfyak, your primary forms will be one at the centre ( crotch location ), one at the peak of your knee in the exact position you'll be seating, and one at the end of your big toe. These last 2 locations have nothing to do w/ 12 inch spacing, but the others can be organized around it. I found that on average my form spacing is 6", but some are 4 1/2" and others are actually at 12"(going back from the ctr).

The added difficulty w/ squirt design unfortunately is the volume distribution. This usually means that you have to compromise your comfort in order to come close to balancing the volume at the back. It's easy to make low volume behind but up front your legs and toes take a squishin'. Balanced volume distribution is essential in order to control or predict what will happen as your hull gets down. A mystery move is nfg if your bow is always stickin up.

Let us know your progress. And good luck.
