摘要： A multipurpose watercraft has a pair of catamaran pontoons supported by way of a transverse control bar at forward regions thereof. The watercraft may have an arched equipment rack framework extending above rearward regions of the pontoons. The watercraft also has a pair of electric motor thrusters located respectively beneath each pontoon and the control bar comprises a pair of controls operable by hand, each control operable to control a respective thruster forwards or backwards. Alternatively, the thrusters may be remotely controlled. This configuration allows an operator to be pulled behind the control bar horizontally between the pontoons, snorkellers to be pulled behind the watercraft for recreational sightseeing and/or for remote-control rescue operations.

摘要： A speargun having a stock, a muzzle at a distal end thereof; and a pair of matching elastic tackles assemblies either side of the stock for tensioning a wishbone from the muzzle to a spear. Optionally, the speargun may have a second elastic tackle assembly disposed on the bottom of the stock. According to another approach, a speargun component kit may be provided to a user to attach to their own stock having a muzzle; a pair of tensionable pulley tackles having a line to attach a spear, to attach to the muzzle, and to attach to at least one pair of elastic bands at a second end; an adjustable anchor mount of the elastic bands to the stock, and a spear release mechanism.
