Seriously. There's always talk about resetting of anchors. The idea of leaving a boat on one anchor trusting it to reset over and over, sounds crazy to me. Maybe the new generation of anchors are better at this, but I wouldn't leave a boat in that state on any anchor. I've always relied on two anchors set for each change direction. I still wouldn't leave it if wind was forecast.
While it's fun to talk about anchors, I still think how and where you use them, are the most important parts of the system.
