It should apply the ISAF rules. At the moment you can pass through the other boats and go against them and have no penalties...

Hi ! is would be great to allow the users to create some landscapes/cities on their own.For instance, I'd like to create my favorite sailing spots based on marine charts, and share them for free once they're done.

An option to replace controller models with hands models

In races where the boats at ghosts have an indicator. Where the other boats are "real" have a reminder announcement with the instructions. I crashed into someone and ruined their race thinking I would pass through.

Wind shifts and gusts would be good.Sailed in a snowstorm once and the pattern of snowflakes across the mainsail was an eye opener

Rain, gusts and waves

A dynamic Wave model that also shifts the boat off course

Be able to raise and lower sheets for when I want to dock or at least not cruise at the shore at 10 knots
