If there’s one thing that ruins a great day on the water, it’s a fouled propeller. At best it’ll hold you up while you take an icy swim to free your prop; at worst, your running gear could be badly damaged. Wise cruisers guard against such scenarios by installing a line cutter like the latest-model Shaft Shark. Bristling with even more razor-sharp serrated teeth than its predecessor, the two-piece line cutter is easily attached to your prop shaft just ahead of the propeller, where it’ll make short work of ropes or weed. It’s available in a number of sizes to suit most shaft and prop hub diameters; there is also a saildrive model.
