There are many outboard motor lifting cranes available on the market. Most of them are based on a pole with a horizontal boom or crane attached. If you have a pole mounted on the stern of the boat, why not be able to use it for multiple purposes such as a solar panel mount, an anchor light mount or an antenna mount? I started out researching poles made by various manufacturers including Garhauer (my favorite) and concluded many were over designed for what I needed or didn't offer multiple features. Taking the best of each and adding my own ideas, I built several prototype poles until I came up with a design that fit the needs of the cruising sailor yet could be manufactured for a competitive price.
