The cost of a survey...
often depends on the type of survey you want, the type of boat to be surveyed, and the distance the surveyor must travel to get to the boat. I've found that surveyors along the east coast may charge anywhere between $10 to over $30 per foot for the "average" pre-purchase survey,plus expenses. That may, or may not, include the cost of joining you for a sea trial (a must, IMHO) and or going up the mast to take a look at how things are at the masthead. Some surveyors are qualified to inspect your engine, others are not. I recommend talking to other boat owners, particularly ones with the same boat you may be buying, to get a recommendation for a "qualified" surveyor. You need to interview a potential surveyor to make sure you are both on the same page about what he can or will do and what he cannot do -- and how much that may cost. You also want a surveryor who has surveyed your type of boat before and you can ask to see copies of those surveys. You do not want a surveyor who is surveying your type of boat for the first time. Finally, there are a number of organizations that "certify" sureyors (i.e., NAMS, SAMS, etc.). While it is preferable for a surveyor to be a member of one of these organizations, being a member should not be construed to mean he is qualified. There are currently no national standards for a person to call him/herself a "surveyor." You've got to do your homework about a surveyor you plan to hire just like the research you do on your next potential boat. Good luck with this.An afterthought: always join the surveyor when he is doing your survey. Ask him questions about every finding he uncovers. You'll learn a lot.Afterthought II: you should do your own "survey" of the boat before the surveyor does his. Get a copy of Casey's "Inspecting the Aging Sailboat" to get some ideas for what to look for. Then compare notes with what the surveyor finds.
