Wow... you guys need to race some mono's.

You defend your wind at all costs. You make it clear that you will take a competitor up to head to wind if necessary... should they try that kind of pass. You may lose that race to others who laugh and say... have at it boys and happily sail to the next mark. ... BUT... they won't try the same stunt on you in the next race.. Even boats in different class's won't let you take their wind (cause they get crushed in their class sailing in your dirt... pain is in the eye of the leeward boat).

IMO, Take a boat head to wind... this is a seaman like maneuver that everyone should be able to execute. . .... If the crew on the attacking boat... can't manage to execute the maneuver and capsize in the process... They will foul and take the penalty. Nothing says that the round up maneuver on your particular boat won't mean that you won't have to snuff your chute as a standard practice.

The reality is... the boat clear ahead is looking at the spin boat and coming up to defend and coming up to defend and coming up to defend. If the spin boat doesn't get the message... don't go there... I will luff you up... the spin boat is clueless about racing or simply trying to bully the non spin boat.

As many have said... if you want to pass to windward.. you need to get to your passing lane early... Sailing up on a boats hip... is NOT the proper passing lane.
