Yea ive always wondered about raffting up seem cool to raft up with other boats. The problem with me is i don't know other people with boat and when i come into a anchorage and there rafting up i usally just pick up a mooring or fall back away from them and anchor
off. around here u never see boats rafting up at a dock. Also theres uslally more room for a boat in from or in back. But there isn't any public docks so don't have to worry about transiting them.
