Canibal surfboards in Florida builds custom kite construction boards that are vacuum bagged. He tints the epoxy for custom designs. Shaped by hand so you can get whatever you want. I have been using the Condiut model and love it. It has a diamond tail so great for light wind and has more pop than a narrower rounded tail. It works good in high wind 7m as well. I plan to order another with straps and slightly smaller.
Every time i get on a production board they feel heavy and super stiff in comparison. They ride like a poly board but are super tough. Probably 50% lighter than a production board as well. Price is less than big names as well. Haven't ridden a better board and i have no affiliation with them.
