I never really had a problem when I bought my first boat 10 yrs ago. - 26 yrs. old, 25' Baja with a flashy custom Checker paint job 454 with wide open exhaust. Boat was loud as hell.
The CG always walked our docks at the begining of the season offering courtesy inspections - or if they happened to be there at another time, you could request one. Showed them I was all good on the Regs for my boat, Lifevests etc. They give you a big ugly decal to stick on the boat saying you've been inspected. After that, the season always went trouble free.
Of course, I was also a considerate boater. I followed all the No-Wake rules, and didn't try to "bump" the speed.
I turned down the stereo to reasonable levels when at idle.
And, I didn't act like an A-hole around other boaters.
Didn't have much trouble.
