I have no idea how it works in other places, but here in California, most (if not all) marinas require a recent survey prior to leasing one a slip. Additionally, most (if not all) marinas require that the boat be insured, with the marina named as "additional insured". And, of course, insurance companies also require a survey. So, unless one has a private dock or mooring (rare in these parts), one pretty much has to get a survey. Might as well do it pre-purchase.
Never forget them. Do something to prevent it from happening again.
