We "daisy chain" all the time at the sandbar. One guy up front anchors to his bridal and three or four boats will piggyback. In 2-3' of water.
Most guys furl the jib, slack the downhaul, center the traveler and sheet-in. They will often just run their mainsheet back to the bridal of the next boat. Then they concentrate on their beers.
I don't advise the "sheet-in" method if you are going to step away from your boat for even a minute. Wind, waves and tides change without warning.
I watched a boat go over in a flash when someone was caught standing downwind (leeward side) during a 90º puff. The boat rolled over them faster than you could say "WTF"!
So I drop the boom and block together now and let the dacron sail swing wherever it wants.
