I don't have the bandwidth for video, so I don't know exactly what was said in it. However, I do know a bit about the old Manta company.
wanted to buy the Manta molds. However, the sailcat molds were in unusable shape and couldn't be salvaged. Gemini did buy the powercat molds with plans to turn it into a sailboat. I don't believe they have any rights to the Manta name, but could probably get away with calling it a Gemini "Manta" - similar to "Legacy" or any other model name. Even that might be a stickler since there is already a sailcat concept
design out there called a Manta, and those guys actually have rights to the name: Manta 46 — The next generation design | MULTIHULLS Magazine
The Manta powercat was specifically designed from the ground up as a powercat - it was a completely new design and tooling, and not just a modified sailcat. It has a canoe bottom with a tunnel and more prismatic than a sailing cat would ever want to have - it certainly was not made to tack!. They would need to completely redesign and retool the hulls to be any good as a sailboat, as well as re-engineer some of the loading and stress areas. The rest of the tooling (deck, cockpit
and interior) would probably work out quite well for a sailboat, although it may be heavier than needed.
