If more people built boats, more plans and options for foils would be available. I dont know what people are busy doing, but homebuilding is declining. I have tried starting discussions on foils for F16s and developments there, and the interest is relatively low, with a few very good exceptions.
I think there's a perception that home-build is no cheaper and much more time consuming than buying off the shelf. And that the boats would be heavy and not competitive
Same reason few people make beer at home, perhaps?
But you indicated in your build project perhaps the most important reason - you have more time than money. Thanks to your detailed site, it does make the concept of a home build a bit more feasible to those who have basic skills with wood and epoxy.
Tortured ply looks a bit less cumbersome than mold-building/sandwich core construction, but I've only built an Opti (which probably weighed 2x what it should have, and lasted about 1 season before it's Viking funeral). But I'd have to find plans...
I think with high aspect boards, that Blade F16 design would be outstanding as a home-build project. But it would likely cost the same as a new Falcon/Viper once you add the rest of the platform (sails, mast, rigging, beams, foils, etc)unless you were good at finding people who are parting-out their older F16 models.
