Good day
I understand and also am in the same frame of mind however I suspect that my dragging incident this week end was a combination of both.
I had a scope of 7 to 1 with 15 knot winds this week end with my situation being well anchored. Then at 6 am the wind suddenly shifted (unexpectedly and not in forecast) my boat started swinging a lot as the wind speed increased with gust up to 25 knots. I will admit that my chain was only ten feet long. I think that the harsh swinging motion with short length of chain made the boat drag. I also need to mention that I had a Bruce anchor in a weed bottom. I could feel the anchor re-hooking but with the swinging motion, the anchor would let up again and again. All three boats in the bay dragged that morning. Rude awakening.
I now installed 25 feet of chain to help resolve issue.
Thanks for your comments
Have a good rest of summer.
Cheers
I think the riding sail will solve part of your problem with the exception of radical wind or current changes during the night. In this case, I would put out two anchors Bahamian moor style.
Years ago when we sailed over to Martha's Vineyard we would always stop in at Vineyard Haven and spend a few days anchored inside the jetty over near the beach between the ferry dock and the town dock. The harbormaster Don Simmonds at that time would always let us anchor our boat in this area provided that we use two anchors Bahamian Moor style as the wind in the harbor changes quite often in there.
I think that the riding sail is an excellent idea because if your boat should slip the anchor at night, I think that you're going to know it pretty quick. The boat will drift sideways with the water banging up against the hull making a racket. You'll not only hear it but you'll feel it, but with the second anchor out, the boat will now be secure and held in place by that anchor.
