More than one type of survey
Insurance companies and lenders only require what's called a "condition and value" survey, which is limited only to those things that could put the boat at risk of sinking or fire and anything that could detract from its "book value." A true pre-purchase survey is one that SHOULD assess the condition of every inch of the boat and every bit of equipment, wiring, rigging etc on it.The same qualified surveyor can do either. Just remember that a surveyor SHOULD work for the person that pays him/her...and that should always be the buyer. Why? Because the only thing the seller and/or broker will be "stuck with" after the sale is the buyer's money...the buyer will have the boat and any problems it has.It would be too expensive to have every boat you're even vaguely interested in surveyed. But never make an offer that isn't "subject to survey and sea trial." That allows you to walk away with your deposit back if the survey should find problems serious enough to be deal breakers (which is rare, but happens), and also allows renegotiation for anything short of that...you can either require the seller to correct to YOUR SURVEYOR'S SATISFACTION, or come down on the price enough to cover any repairs. A complete pre-purchase survey can run $300-500, depending on the size of the boat--about double the cost of a "condition and value" survey." And worth EVERY penny...'cuz I've yet to see a boat--including my own, which I'd have sworn had -0- problems--that didn't need at least enough work to cover the cost of the survey--work you can require the seller to pay for to close the deal.
