Funny thing, I had an older MP in my boat when we did the final round of tests (at Timber). It was a little hairy as we had to go WOT by the MP boat that was about 10' offshore, then take a hard turn to port to clear the point and rocks.
When we were done, the officer thanked me, smiled and said "now I know why you guys like these boats"
I hear you on losing time, I got stopped on a Saturday, and the test was scheduled for the following weekend. That was postponed due to fog. Next week failed and 3rd week passed. Lost almost a full month of boating.
My boat was stock, as delivered by the dealer in Winni. We had a cracked baffle (due to age). Fortunately, that was it.
