New Zealand-based Manson Anchors completed seabed testing in which the 35-pound Boss 2 exceeded expectations, holding 4,200kg (9,260lbs) and bent 5/8-inch shackles.
Testing began with 40 feet of 5/16-inch chain and 3/8-inch shackles and a scope of 5:1 using a 90-ton tug boat.
“We pulled up to 2,000kg (4,500lbs) but bent all the shackles,” said Ned Wood, Manson’s vice president of sales and marketing.
“We returned to the dock, went to a chandlery and bought 5/8 shackles and 60 feet of half-inch chain. Back out testing on the tug again, and pulling on the 35-pound Manson Boss. This time testing had to stop at 4,200kg because the 5/8 shackles were all bending.”
At about the same weight as other anchors, Manson Boss has larger fluke size, which generates more holding power.
