October '06 SAIL...
tested 14 anchors that represented virtually everything on the market. Their conclusion was "results still confirm the rule of thumb that every boat should carry at least THREE different anchor designs and weights to deal with a wide variety of bottom types". Bulwagga max'd out at 2,974lb. load. They concluded "this anchor SHOULD be able to handle the load a 35-40 ft. boat can exert on an anchor with a MINIMUM of 5-1 scope; performance dropped off dramatically at 3-1".Delta, Hydrobubble, Fortress,Manson Supreme, Oceane, and Rocna all topped out at 5,000lb. load, but all had different break out and reset profiles. The one they seemed highest on and most surprised with was the Hydrobubble, "This anchor's performance EXCEEDED our capacity to exert force on it", was a telling comment. Excellent reading, and I thought a well designed test of what is currently out there.
