As keeping your boat securely connected to the bottom is really important for the safety and well being of all distance cruisers, an ongoing discussion of issues about gear and technique can be very helpful. Ground tackle has been dramatically improving over the past few years, and as a result techniques for deploying that tackle have been modified.

This is a great place for members to share their experience with newer anchors and related gear, tricky anchorages, and tips for effective technique.

And if you have a great story to tell, please share it. We all know that anchoring is a spectator sport, and we all love a good story.

Hi Simon,
Thanks for your report. I am sorry you had a re-set problem, although it sounds isolated and under extreme conditions. Still unsettling though.
There appears to be some conjecture at this early-days attempt at understanding, that the scoop aspects of the new generation anchors accumulates seabed which unbalances the anchor so as to make it more difficult for the tip to penetrate when re-setting in a significant wind shift. Those of us with new gen anchors are aware of how much seabed comes up with the anchor when weighed and how stuck this seabed becomes (and how much work it is to clean). When the anchor goes down clean, these anchors are a marvel.
The Spade anchor seems to be less compromised by this tendency, probably as it has a far higher weight in the tip in the form of a lead insert and therefore is less susceptible to the unbalancing caused by a build-up of mud weight.
My best to all, Dick Stevenson, s/v Alchemy
