According to the details this is the only sailing cat that will be there. The show is May 21 & 22 and it's free.
The local Lagoon dealer has a new OV Lagoon 42 in stock so it's probably this one. They built 587 units of this model btw. https://www.yachtworld.com/boats/202...on-42-3012746/
We sailed a Lagoon 42 OV on a charter in the Grenadines a few years ago. Was actually pretty impressed with the boat and performance given it was a charter cat. And dolphins seem to like it as well! I'd certainly consider it if I was currently in the market for a boat that size.
