Not all the time...we were anchored in a nice bight on Rebecca Spit (Quadra Island) and in the morning, with the tide going out and a 35-knot southerly holding us tight on our rode in 10 feet of nice clear water, I decided to move to shelter. We had just re-anchored in said shelter when the wind changed direction to 35 knots northerly. I'd say there was maybe a minute of calm between the two. Our nicely set anchor was actually nicely set in a submerged log, and we hurtled towards the beach with a few chunks of old bark on the anchor. Got the motor going in the nick of time and went back to our old location. We only dragged two or three more times before we found decent holding.Everything Kim says is correct. However I very often anchor in crowded little nooks, overnight at 3:1 scope with the Idea that if the wind where to build to gale conditions, I would add more scope.Set it with enough scope and you should be fine. Remember: Steve uses limited scope in his torture tests. We later tried 5:1 scope and the Rocna reset well. (It used to be the conventional wisdom was 7:1 scope, but with crowded anchorages everyone now shortens up a bit. No one recommends 3.5:1 for serious anchoring, Steve just does it to really challenge the anchor.)Well, I sure was happy with my Rocna compared to my CQR. Performs really well, unambiguously better than the CQR.
But now my confidence is eroded a bit.
I guess I can convince myself that in my safe little hidey hole anchorages, i'll typically be drifting slow enough for a good reset in the event of a wind shift.
I'll note that out here in the PNW we never get significant Thunderstorms. Our BIG winds result from larger weather systems and are quite steady in direction.
