One point to notice is at the end of the "West Marine" test article--is that the wise sailor has 3 different type of anchors...For our cruising boats that was a plow, a Danforth HT and a fisherman.
Don't have a fisherman for the C Dory, but carry several #7 Fortress, and one #11 Fortress--the 10# Boss, and a Delta Fast set on the c Dory.
It is puzzling that the Wast Performance anchor did not do well. I tend to agree with the authors, that the West Marine did not have as sharp flukes as the Fortress--and the original Danforth--which it was copied from.
The "hooker" and Danforth type--are never as good performers as the sharp edged, "T" spine on the fluke High Tensel Danforth. The Ronca. Manson Supreme,Mantas are all good anchors and will do well.
