Re: Should I be scared??? What would you do???
For a first time buyer/new sailor I think the 'sailing' portion of a sea trial may have limited value, in that the buyer may not be able to tell if the boat sails well or not, and it's a crap shoot whether you get good sailing conditions in any case. But the opportunity to check running systems, vibration, noise, leaks, full functionality is the larger part of what a sea trial is for. Ideally your surveyor is along for the ride...
In the east where boats are routinely hauled for winter I'd think the mechanism for delayed closing should be a common practice. I'd stay away from a broker who minimizes or recommends against a sea trial on principle alone.
