Yes, and this will make me wonder what is going on and where the 'trap' is, what is the tactical ploy going on. That the other boat is intimidated and dont trust me enough to keep clear comes a long way down on the list. If I see it of course, but situational awareness is very high on the list when racing! Goes with keeping my head out of the boat and letting the crew worry about boatspeed.

As for intimidation, if the other boat dont see me, I slow down or do whatever is required to avoid a collision, as pr. the rules and common sense. The wolf whistle is handy here, as it carries a long way. But if the other boat is not so close as to be protested under the rules I dont know what to do except striving to keep similar boats on the same courses and not mix them. Alternatively, building opaque spis (I am sure I saw some such a time back).
Keeping the boats separate in smaller handicap events have its owns challenges and problems.
