Unfortunately, we have two different problems here. The washout of the railroad tracks and boardwalk were one event, and monies for the reconstruction of those areas came from one source.
Your damage is caused by maintenance, or perhaps lack of maintenance, of the docks themselves. Sorry for your damage to your boat, but I must ask: Did you have bumpers out?
I think I saw bumpers on Shipshape TV on Comcast Sports, the old Foxsports, that were inflatable and thus could be blown up for use, and then deflated for storage. The segment stated that many of us use bumpers that are too small or don't use any at all simply because it is difficult to store bumpers of the the proper size. By being deflated for storage, it is easier to store the bumpers when not in use. Inflation only takes a few seconds.
And no, I never bought any.
