[C320-list] Through hull for new AC unit

[Jack Brennan]

The funny thing about insurance is that I’ve never been asked for a survey, even though I’ve owned sailboats off and on for 40 years in Florida.

<rant>It’s probably just as well, because most of the surveyors here aren’t worth a damn. After shelling out 1K for a worthless survey on my 320, I decided I would self-survey from now on if I ever buy another boat, although I suspect this one is it.

They don’t check the diesel, they don’t examine the rigging. In fact, they tend to turn a blind eye to all but the most trivial of problems because if they slam a boat too hard, word gets around among the yacht brokers so they don’t get any referred business.

Mostly, they just turn things off and on to see whether they work, tap a few obvious spots on the deck to find saturated core in places where it’s not important and ignore all of the haphazard wiring that could catch your boat on fire one day.

I bought my 320 from a bank that had foreclosed on it, and the supposedly reputable surveyor missed almost all of the sabotage that someone had inflicted on the boat, either to get revenge on the bank or just for the thrill of vandalizing.

In fact, he didn’t even find the stuff that I had already identified before hiring him. It was lucky for him that he asked for the check before he wrote the report.</rant>

Apparently, it's a common enough practice to cause Groco to make a manifold to meet the demand.

I guess having less holes in the boat has it's merits. Still, I would seek the advice of a surveyor on what is acceptable. You WILL need a survey at some point, either for insurance reasons, tr to sell the boat. Might as well do it "right" the first time.
