The intention of this project is to create a dual purpose outboard motor hoist mounted off the back of a sailboat. The first purpose of the hoist is to raise and lower the outboard motor, in order to aid the user in the process of installing the outboard motor on the back of the dinghy. This is achieved by the use of a pantograph system, causing the outboard motor to remain in an upright position at all times. The upper half of the hoist will be fixed to the back of the sailboat via the railings, while the lower half will raise and lower by the power of a winch hand cranked. The motor can then be lowered directly onto the back of the dinghy where it will be fastened and ready for use. The need for heavy lifting is eliminated. The second purpose of the hoist is to allow the outboard motor to act as a secondary, or back-up, propulsion source. In the case where there was no wind and there was an issue with the sailboat’s primary motor (if the sailboat has one), then the outboard motor can be used to propel the sailboat.
