On our Lightwave 10.5 we use a 16kg SARCA Excel with 8mm chain as our primary anchor and a Spade, alloy, A80 as a secondary anchor. It depends where we are cruising, but we might also carry a further 13kg Excel. This combination has proven exceptional.We anchor in some locations that can be taxing but neighbouring yachts in the same anchorages commonly employ different anchors including Bruce types (we test the Claw and the Ray here), CQRs, Deltas and Manson Supremes and the owners seem equally happy. Our anchor choice was based on what we thought was the best — but presumably their anchor choice was also their best and maybe their anchors were lighter, or heavier, than recommended — it would not do if we were all the same.In this section we look at the ability of anchors to set and re-set in different seabeds — trying to simulate changes in wind and tide. Simplistically, we set a range of anchors, in the 5kg to 10kg range, then subjected them to pulls of 90 degrees to the setting direction and 180 degrees to the setting direction. We conducted the tests in different seabeds using different loading techniques. We used a small runabout with a 60hp engine to set anchors at about 9...
