I am inclined to agree with you. I think people in general who don't own a PWC don't like PWC's. There are probably a lot of complaints called in to the MP about PWC's, and in some cases with good reason. I think it is a factor of a few rotten eggs spoil the bunch, or something like that.

I have been stopped a couple times on my PWC, both times with similar instances you had...phantom 150' violations. They were so far away, there was no way they could tell how close I may have been to a particular boat. My guess is they think they may have seen a 150' violation, and pull over the PWC no matter what. Gives them an excuse to check safety equip, boaters certs, etc.
