What this video covers
A 44-lb Rocna anchor demonstrates significant mud-fouling tendencies during underwater testing in the Pacific Northwest.21:59 In sandy mud, the anchor consistently fails to reset after a 180-degree reversal, as it retains a large, cohesive blob of seabed that prevents the fluke from re-engaging.11:50 While the anchor achieves an instantaneous initial set and performs well in soft mud at Scow Bay, it produces lower holding power in sandy mud than other 44-lb anchors, including the Bruce, Delta, and CQR.24:00 The tested unit exhibits a slight, permanent bend in the shank, though the construction remains robust with generous scantlings.2:57 Testing occurred in 26 feet of water using 105 feet of 3/8-inch BBB chain at a 3.5:1 scope.4:43 Increasing scope to 5:1 or greater likely mitigates the fouling issue, but the anchor’s performance in common regional substrates at short scope warrants caution.24:42 The anchor’s geometry, specifically the acute angle between the shank and fluke, appears to facilitate the accumulation of seabed material.23:32
