Another vote for Rocna. However found you need to NOT back down on it in the loose mud of the Chesapeake. Just wait 10 to 15 minutes and then back down gently. In very loose mud a fortress maybe necessary. But that’s very rare.
However in places where you go 180 from tides you need to have room for it to reset. So far have found my current Vulcan does just as well as my prior Rocna overall and has no troubles at all with a 180 shift. From experience it may take some space for the Rocna to do it. Plows of any form perform poorly unless you pay more attention to deployment than I’m willing to do at the end of a day. Rocna or Vulcan drop it and you’re done.
Think any of the nexgen anchors are head and shoulders above the performance of prior anchor models. You can feel secure with even 3:1 if necessary. But think the Vulcan is the best of the lot for NE. We have a Vulcan one size up and a fortress two sizes up. So far so good.
