It’s been mentioned in another post, but I feel like this should have it’s own ticket.
Having boat capsizing would be an interesting feature and would make maneuvering more challenging overall.
This could be implemented as an option for training (so beginners don’t get too frustrated at first) and disabled in the standard race, but be made mandatory on pro, dinghy and waszp races (and any other specialty boats to come).
That would make for a more realistic boat behaviour, and could also have new sailors get used to proper techniques if they wish to actually do sailing on actual water.
