In concurrence with more dynamic weather option, having the possibility of then adjusting your main / jib would be awesome in the future.
Right now on the Quest 2 it is a fun experience and allows to feel like your spending a bit of time on a water like environnement, but it is a little too "arcady" and feels a little like driving. Point towards a heading, adjust a little your sheets and then just wait til the next tack.
With dynamic weather / wind direction and strength change you would have to be more on the lookout and adjust things more, improving immersion. Same with using the physics of MarineVerse Cup that feel better than the ones currently in BBB (behavior of the oat and the finesse of the sail adjustments)
Overall, the game is a great fun basis that could become an amazing VR experience for learning and improving and getting a taste of cruising.
