When judging the worth of an anchor there is generally only one question: Will it keep my boat put? Answering in the affirmative is how Rocna is making a name for itself. Designed by Cavalier Yachts co-founder Peter Smith, Rocna anchors feature a large, self-righting roll bar, ensuring the blade is always at an ideal angle to the bottom. Ranging from 9 to 606 pounds ($149 to $10,600), the anchors have a proportionally large blade area for strong holding power in varied bottom types. If the wind and tide change direction, the roll bar should allow the anchor to automatically reset itself.
