It occurred to me that there could be a whole bunch of boats trying to tie up at or near your dock for burgers and dogs, etc. Everybody should bring at least one pair of hoppity hops. For those of you who never "raft up" these work great because a normal fender will still let board racks bang into each other. The hoppity hops keep the boats a little further apart and work great for rafting up. Here's a site that has them pretty cheap and has 3.95 shipping for your whole order:
