Ranger tugs are neat wee boats. I was just recommending them to someone just minutes ago. They can be trailered, and that opens up cruising grounds that otherwise might well not be feasible, e.g. inland lakes, or places realistically too far to sail to on their own bottom. We made good use of a large maxi trailer yacht to do most of the North Island lakes and the Bay of Islands in NZ when we lived there, for example.

Welcome to the forum as another Aussie based boatie. It's funny, Mac does't like the expression boatie, and always tried to make it boat tie, or boater, which is the North American version.
