Frank Webster made a comment on another thread about Sea Ray carefully mating anchors to their boats to assure proper ability to set the anchors. We were a 2 boat raft this weekend with a Formula 45 next to me just using my anchor, no stern. In the first pic below are a 52' Cruisers, 42' Cruisers, and a 32' Cruisers. The 52 and the 42 both had anchors out. Very mild conditions, no wind, sandy bottom. You can see where they ended up in the 2nd picture. We never moved according to my GPS and Anchor app. (Not sure why I have the same pics multiple times, but you get the gyst of it)
