Not for nothin', but you might want to consider a Fortress for mud bottoms. It's the only anchor I'm aware of with a) adjustable fluke angle that b) can be set specifically for mud. The standard Danforth fluke angle is 32 deg., which the Fortress also has, but the Fortress can also be set to 45 degrees.eodjedi wrote:Wish I had some mangroves to anchor to. Alas, I had to count on the muddy ground I was stuck on to hold me steady.
I've found through experience that the standard 32 deg angle is next to useless for mud, as it drags too easily, but set to 45 degrees, it sets easily and will bury itself to where I have to struggle to get it out. But it doesn't want to set at all in sand, and just sort of pops out or skips, until I reset to 32 degrees, and it digs and buries itself in sand.
I took this in Lake Simcoe, which is halfway between Lakes Ontario and Georgian Bay in Lake Huron. Clear water and clean sand near the beach, with light wind and mild wave action. It wouldn't set worth beans, and skipped and set, skipped and set, until I realized I had it set to 45 deg for my local sailing grounds (mainly mud). After I realized what was happening and reset it to 32 deg, it buried itself with no effort, though I may have backed down on it a bit when setting.
It's only an FX-7, which weighs a mere 4 lb (aluminium), but it's the largest that fits in the anchor locker. Roughly equivalent to an 8-9 lb Danforth. I think the has a larger locker, thank goodness. I also keep a larger fluke anchor, plus a larger Claw, down below just in case.
The next gen roll bar type anchors are not exactly known for mud holding ability, but then, I don't know of many others that actually are good at mud holding other than the Fortress. If I had a real bow roller, I'd keep a nice size Rocna or Mantus on it (like yours $$) or a Spade ($$$), with a larger Fortress down below, rigged and ready to go, in case of emergency, and/or winds and waves with a mud bottom, which seems to be something it excels at.
For its size, of course, as tossing a 500 lb anchor of almost any design overboard would hold the boat in a blow.
