I have just watched a yacht with a Bugel anchor
try about 5 times to set their anchor
(they even dived on it twice) with no success and they left the anchorage
The conditions were medium hard sand, no weed, 5m (16 feet) depth
. There technique was textbook with lots of scope
I rate the Bugel as one of the top 5 anchors so I was puzzled at its poor performance, but looking at the tip of the anchor the last 4 inches of the tip were bent (down about 15 degrees)
The message is if your anchor is bent, even slightly, the performance in some conditions may be very poor.
Unless you have a CQR
where a change in geometry could only be helpful.
