The "essential repairs" noted on my survey didn't give the underwriters any terrible heartaches. I was given 30 days to address them (hose clamps here and there, battery terminal insulators, horn- minor stuff similar to what you have listed). The policy did indicate that any losses due to these items would not be covered during that 30 day period. They were very reasonable about everything. I used Charter Lakes Yacht Insurance, for what that's worth.
