I use a 2-anchor Bahamian moor frequently, and I did so in the
Bahamas too. Part of the reason is that I frequently
anchor in some tight little spot that nobody else would
anchor in, so I couldn't swing without going aground. Had a gorgeous anchorage like that up Pipe Creek where at low tide we were in our own little pool with sand all around. Used to do the same in Warderick Wells before the moorings. Lots of great
anchorages in the
ICW in narrow creeks with reversing tidal streams. In any area it is a great tool for reversing tidal streams and narrow
anchorages, but has other uses too. In crowded
New England harbors I use it to limit my swing so I can anchor close to something like the edge of the dredged deep
water. It is also useful in frontal passages to prevent reversing the pull on your anchor suddenly. I have seen some
wind switches that were so violent and sudden that the new
wind came in on the stern of my
boat and sent us whistling away down wind until the end of the anchor
rode was reached with a violent jerk. That can pop out an anchor. One trick to deal with the winding up problem is to make the second anchor up with mostly nylon
rode and keep it in a sail bag. When the lines twist it is easy to pass the bag around the chain and untwist. I have sat on two anchors for weeks at a time with maybe an extra 5 minutes a day attention paid to unwinding the rodes like this.
