Here in Fort Lauderdale, the yachting Capital of the US, it would be very uncommon not to have the buyer on board for the survey. I tell my clients that it is critical for them to be onboard for the sea trial, if not for the entire survey, sometimes on a larger boat that may be two or more days for survey. If a surveyor said they did not want the buyer to take up their time asking questions I would suggest a different surveyor. Many times a good surveyor will verbally explain a finding differently than in his written report, explaining how an item might be repaired or updated in different manners at different expense levels.
Typically at the end of the day after the sea trial we all sit together, buyer, brokers, and surveyors to go over the findings. The surveyors will look through their notes and talk about the highlights and explain and answer questions on the spot. The written report comes later but the buyer has the important stuff on the spot. Many of the surveyors are booked well in advance and cannot come back easily another day. There is an engine surveyor here in Fort Lauderdale who has done over 5,000 engine surveys and he is booked enough it is hard to get him on short notice.
Here in Florida we often sell boats for buyers and to sellers who do not live nearby. Often a captain is hired for the day to run the boat and I ask that the seller be available to answer questions by phone.
Tucker,
Excellent post, sounds like the BEST way to handle a survey!
