I just got the survey on a Hunter Legend 40.5 and it states "Some bonding terminals/connections have corrosion, inspect and service the entire bonding system. The keel to hull joint has a small crack aft, clean and keep dry, adjust keel bolts. Service the entire bonding system, some corrosion on the wiring terminals." This is the only issue with Geico Marine insurance and it states it needs to be repaired to be insured. So, asking for guidance. Is this something to walk away from and say no deal? How much would a repair like this cost? Do they have to drop the keel to fix this?
