In the US, I’ve also encountered many recreational boaters that love the Claw or Bruce anchor. It’s a type of plow anchor that’s a notch above your common Danforth since it also does well in rocky bottoms. However, it can be quite a struggle to get it to bite sometimes, and to me, it’s slightly inferior to Danforth anchors in terms of holding power.
Mighty mite or rebar... the mighty mite is aluminum and won't rust. Just don't use a Danforth or Bruce Claw... the jetties are littered with anchors and anchor ropes from people trying to anchor with these anchors. I was even filming a guide boat in a tourney and they got there anchor stuck.. had to use the outboard (300) to try to break free and in the end the rope failed.. leaving most the rope and the anchor in the channel down on the bottom. I'm sure there's 1000's down there.
