A 50kg (110lb) genuine Bruce anchor undergoes a series of holding power tests in mud, sandy mud, and cobblestone seabeds.0:32 Using a 25-ft deep test site and an FX-85 Fortress anchor as a deadman, the 50kg Bruce is pulled at an 8:1 scope using Dyneema rode.1:03 In sandy mud, the anchor holds up to 2,400 pounds of force before the deadman anchor begins to drag at a 5:1 scope.22:59 In cobblestone, the anchor remains upright but provides only medium holding power, consistently peaking at 460 pounds.17:29 Scaling studies show that increasing the Bruce anchor size does not improve holding power per unit of weight compared to smaller models, with the exception of the 5kg version.15:08 The 50kg Bruce requires manual assistance to launch and does not self-launch.25:10 Increasing anchor size does not linearly increase holding efficiency in the Bruce design.15:01
