This invention is a surf-launched, a submersible, self-righting radio controlled boat. It is one meter in length, 30 cm wide with a draught of 25 cm. The boat is electrically powered and operates on two 8amp/hour dry cell batteries which power a 200 watt motor to which a 3:1 ratio reduction gearbox is attached driving a 115mm 3-blade propeller. It is ideal for delivering a baited fishing line up to one km in oceans, dams and rivers. It is ideally used in conjunction with a battery-operated motorized winch whereby a line from the winch is attached to the boat in addition to the fishing line. Once the fishing line has been released, the winch pulls the boat back to shore. Other applications include underwater photography, recreation or life-saving where the boat itself, fitted with handles becomes a motorized life-buoy or the boat can be used to tow a life-buoy to a drowning bather. |
