If you're rafting with other C-Dorys, here are a few tips, in addition to the excellent ones already given.
Assuming only one vessel will set it's anchor, any wind will cause that vessel to present a moving target to the first couple of rafters, since the first one will swing back and forth on its anchor, like a pendulum. The second vessel should approach slowly, from the stern, at the approximate mid-point of the swinging vessel's arc. As the swinging vessel moves past the mid-point, the second vessel moves forward slightly, and holds in place, waiting for the swinging vessel to return. I prefer to make the first raft up between the port side of the anchored vessel, and the starboard side of the one raftng up. That way, and skipper of the vessel under power (the one rafting up) can take a line through the helm station side window, and assist in tying up.
As the anchored vessel swings back into the other, be ready to pass two lines: one between the mid-ship cleats, and another between the stern cleats. Snug them up against the fenders, which were in place before the raft up was begun. Forget the bow line: a tie-up between the mid-ship and stern cleats will keep the boats securely in place. The bow line will add nothing to the arrangement.
Once the first raft is made, those two vessels have a far less tendency to swing at anchor, and as the raft proceeds on alternate sides, the problem goes away altogether. Just remember, raft from alternate sides, and don't attempt to raft, or approach it closely, until those already rafted signal that they're finished securing the previous vessels, and are ready to accept you.
If only one vessel is anchored, those closest to it should have their anchors ready for immediate deployment, so that if the first one slips, more can be set without having to break up the raft. If multiple anchors are to be set at the beginning, do as previously suggested, and join the raft by letting out rode, instead of powering forward into position.
Have fun!
