Rocna 12kg MkII

• Brand: Rocna

The Rocna Mk II is a refinement of the original Rocna design, which has built-up a reputation for reliable quick setting and secure holding power over years of real-world experience and feedback from thousands of boaters. Smith has also used patented technology shared with the Vulcan anchor, such as the “I+V™” shank, which helps make the Rocna Mk II the toughest of all Rocna anchors.

The innovative anchor features an all-new patented “roll-foil™”, a sculpted variation of the original roll-bar which features a series of unique shaped profiles designed to further assist the anchor’s critical self-righting behavior and help during setting for deeper penetration and additional holding power. The fluke also has had a major overhaul which optimizes the original Rocna pattern for greater surface area and improved weight distribution.

Our sizing is conservative
Our sizing recommendations are intended to provide an anchor adequate for use in most all conditions. We base our calculations on 50 knots wind, associated surge, and poor holding bottoms. For more on our philosophy and rationale, please consult our knowledge base article:

If your vessel is outside these specs then ref to Rocna range and sizing chart for correct anchor size.
