Weird topic. It's all over the place!
As someone who sails, windsurfs, wings, and even kites on holidays..
2 things.
#1 I'f youre parawing/winging etc under wind power. Yep starboard right of way applies. But it's starboards obligation is to hold course and allow port room and time to avoid, and port must alter course. Starboard doesn't have rights that mean everyone must stay away
So if you're on starboard and nearing someone else on Port, pick a course and stick to it. This can be tricky on a foil. If you cannot do that, then it's your responsibility to stay further away from others.
If youre going upwind on a parawing at North haven, then You aren't just passing through on a downwind. You're in the train of riders. So either join in the 'rythm' of the crowded spot,and be ok with people being close to you, or go out to sea on Port and sail around the crowded spot.
2# sail power vs unpowered.
You still have an obligation when unpowered downwinding on a foil or canoe to allow a sail powered craft time and opportunity to avoid after each speed and direction change is made.
So if you're rapidly steering through 90 degrees to stay on bumps when foiling, it's best to just avoid a populated windsurfing/wing foiling/ kiting spot if you can. Windsurfers should also keep clear, knowing the downwinder is changing directions and is dictated by the waves. A bit of space from both parties makes sense here.
