Hi Noah
We've anchored in Mariners basin twice in the last 1.5 months, both times near the entrance in about 22ft with 3:1 scope. No problems with our Rocna 15 setting, and since the Manson is so similar I'm curious why you would have. The anchor came up relatively clean (nothing like La Playa) but the bottom was definitely mud. I did break down and add a Mantus swivel last year, mostly because the Rocna would invariable come up backwards, but I hadn't had any problems anchoring with the shackle-only anchor connection before. I doubt if that's the difference.
