I've had good results with the Fortress Commando anchor system.



It includes the Guardian G-5 anchor (2.5 lbs), 6' of chain, and 150' of 1/4" nylon rode. I attach it to my boat with a bridle on the N6.0's bridle wires. I don't keep the bridle attached while sailing, but rather use a couple of small biners to attach it when needed (requiring a balancing act to walk forward on the hulls).

The anchor holds very securely in sand, mud, or other soft bottoms. It is not recommended for rocky or hard bottoms, as others have pointed out.

I also use the system while leading kayak tours in Mexico/Belize (just returned from one a few days ago). When we snorkel, I anchor my kayak with the Commando system, then tether the remaining 10 boats beind me on a line that resembles a big fish stringer. The anchor has no problem holding 11 kayaks (combined weight of over 600 pounds) in winds up to 30 knots. The anchor is set in sand, typically in water 8 to 15 feet deep.
