Maybe I’m missing something here, but isn’t this like getting an appraisal and expecting the appraiser to come up with the value that you want?
If the insurance company wants a survey, it seems to me that the survey should reflect the opinion of the surveyor on all issues which are addressed, and that the surveyor’s competence, reputation, and integrity rest on this happening.
If an item is not included in the realm of the survey, then it generally is excluded in the surveyor’s report with some type of exculpatory language. All of the other conditions (and particularly items with which the surveyor “takes exception”) ought to be reported.
If the cabin sole varnish is worn through, all the varnish is peeling off of the brightwork, the gelcoat has chalked away completely or the awlgrip has blistered away, and someone has been playing darts against the main bulkhead, then these are all items “of interest” to the insurance company. They may not impact the survivability of the boat, or its usefulness, but they certainly factor into the value of what’s insured. If the boat is gone, sunk in 600 fathoms, burned to the waterline, or stolen, it’s pretty hard to make a case for its “pristine condition” and “bristol finish” without having something to back it up.
All insurance policies are either “agreed value” or some factor of (depreciated) coverage limit and/or replacement cost. All conditions affect all of these values. You can’t just “overinsure” something that’s worth $50,000 with an agreed value of $100,000 and expect them to pay off without some assurance that the item was (and continues to be) worthy of the coverage value.
The survey won’t reflect that the captain’s bunk was unmade, and that the galley sink was full of dirty dishes, but, if the engine sounds like a Messerschmidt in a power dive and the rats have gnawed all the wiring to the nav lights, then those things will be mentioned…and the insurance company is entitled to know them.
Get the survey with the idea that the deficiencies noted therein will be addressed before/immediately after it is submitted. Invoice copies may be requested by the insuror for needed-work noted in the survey.
When I was buying my boat, the Halon cylinder had been dismounted and put in a drawer by the PO. This is a self-contained item, held to a bulkhead in the engine compartment by a metal band clamp. The surveyor noted that it was “present, but not installed”. The insurance company wanted the survey as a condition of coverage. I sent it. They bound the boat, I bought it, then they sent along a letter asking what I’d done about specifice deficiencies noted therein, and gave me a deadline for responding to them. The list was not all-inclusive, but the Halon cylinder was on it. They wanted “proof of the work”. I sent a copy of the itemized yard bills which addressed some of the issues, and took a picture of the re-installed Halon cylinder (and the backup for it which I also obtained). They were happy.
If you need the survey for new insurance, just plan on doing what looks to be important and then proving it up.
