Ditto for our dinghy propulsion. On Elizabeth, Carlotta and Corina, the first three cruising boats I was involved with, I rowed our tender. However, as our family grew, I aged and our ability to anchor cheaply pushed us to more challenging locations in more remote areas, the distances to shore became too great. We used a 2 or 5 hp engine during all our circumnavigations. The motors were small enough to be easily lifted and yet powerful enough to push a loaded dinghy against a major squall.
While living aboard in the Virgin Islands, our dinghy acts as our car. Just recently, I purchased a 10 hp Tohatsu so Carolyn and I can plane off between St. John, St. Thomas, Jost Van Dyke and Tortola. This saves us vast amounts of time and money, and has no drawback in terms of weight because we rarely remove the engine from the tender. In spring 2018, when we leave on circumnavigation number four, we will probably trade it in for a 5 hp Yamaha.
