Few weeks back my trailer was involved in a hit and run at one of the local lakes.Only damages was to the port side fender, which needs to be replaced. I put in a claim with my insurance company. New fender from Bass Cat is $345, plus shipping. My insurance company is giving me $241.50 for the fender, plus shipping costs.They said 30% depreciation for the fender because the boat is a 1998. Is this normal practice with boat insurance? Thanks in advance!
