Yes, that was our experience too. I would not compare it directly to stern anchoring, though. What we experienced was that we became "part of the sea" with the JSD, whereas when you are anchored to the stern you really would not want a breaking sea over the boat (except that you've chosen a really bad ancorage if that happens ). I'm not against anchoring at the stern, actually I'm thinking of adopting that, to prevent yawing, it's just that I feel that the two things only share a minimal subset of characteristica?

Therefore, if moving backwards, the boat will be unstable and will yaw and turn broadside to the sea.

Makes sense to me. Same idea as stern anchoring, no?

Dare I say center of areodynamic resistance is best downwind of the center of hydrodynamic resistance? All ducks in a row.

The reverse: boat lashing to and fro? And if one of the fros coincides with a drop or surf off the crest, big loads no?

Hoo boy. I will shut up now.
