Yeah, I think that's it, or close enough. I have a smaller one, which is fairly wide at the top, narrower at the bottom. I bought a bigger one this season, because the Mantus anchor is bigger than the old Claw. I hope I can fit it into the lazarette ok. I keep it below decks in the lazarette with the rode flaked inside, chain on top, and anchor perched somehow, and it only sits on deck when anchored. And my anchor time isn't nearly as long as TSBB2's... He's right about rubber deteriorating over time, just ask the old rollers on my old trailerIs this the one you are talking about?
