I'm far from a buyer - Weebles is likely the last boat I'll own (famous last words). But if I were in the market, would very likely be a pretty standard displacemen/semi-displacement boat in the 50-foot range. Here's how I would approach it (and if I were a seller, I'd be fine with this too).
In the Agreement, I would describe:
1. Approx 3 hour Sea Trial based on the Check List I offered up-thread (re-attached for convenience). Although it's in the document, I would inform broker that I ask the sea trial to be a standalone event, and it should include a WOT test of at least 5-minutes followed by a 30-min run at 80%. Seller to operate the boat. I would take engine oil samples at that time. On more sophisticated boats, I would pay very careful attention to the electronics and integration because it can be incredibly expensive to resolve issues.
2. Mechanical Survey by a marine diesel mechanic, but only after I have accepted the Sea Trial and have the oil analysis in hand. He will need the engines started again, perhaps want WOT test again. I know it's inconvenient, but not out-of-line in my opinion. I would be open to paying the Seller's captain a reasonable hourly fee to return to operate the boat.
3. Hull & Valuation Survey. Only after Steps 1 and 2 are accepted would I schedule the full Survey.
I would probably share the results of each step along the way, but would try not to negotiate until I have all the information. Exception would be if I find something that is a deal killer issue - over-heating during WOT would be one reason. But generally, I would make the seller aware of my findings and then present a revised offer based on the findings at the end. Would be a case-by-case basis.
Given the discussion in this thread, I know there are folks who would not be comfortable with my due-diligence process and would kick my offer to the curb which is fine - no sense either of us losing brain cells. In my mind, I don't want to get stuck with a boat with surprises. I would hope both the broker and seller would appreciate that, but it takes two to dance. To my defense, I'll repeat what I said in the opening paragraph: I'd be fine with this process as a seller. Sure, it adds several days and perhaps an extra ride on the water, but I think it's a fair process.
