I am pretty sure he is talking about using mooring balls, such as Vero Beach, Stuart, Fort Meyers beach, Naples, Key West, Marathon and off some of the park Keys like Shell and Lignum Vitae
We've put our 56MY on most of those, and granted we have much higher freeboard and more windage. It would be difficult single handed, especially if you have some wind. Just getting positioned by the ball without running it over can be tough without a lookout. Typically, because mooring designs vary, the best plan would be to sidle up to the ball, have an already bow cleated line handy, and snag the painter with a boat hook, loop you bow line through the eye and "walk" the painter forward, and to the same cleat where the other end of you line is tied. If conditions allow you =want to get another line on the painter and tie it off to the other cleat. When things are calm you can put them both through uncleated and then tie them off to their respective cleat. You do not want to simply pass a line through the painter eye and cleat it off to each bow cleat. You will have chafing issues and the boat will horse around a lot more.
Call each harbor master now and talk with them as to how the moorings are currently configured and what best/required practices are, as well as reservation requirements, etc. Find out if there is a launch or a way to enlist helpful neighbors to help get the painter to you or tie it off. In the larger fields, if there is someone around they will often come help as it is a pretty good community and they don't want your boat drifting into theirs. The mooring fields vary in design of the mooring. The more you can use your own line to attached to the mooring chin itself, the better; I once had the eye of the rope painter break off in my hand at Vero Beach. I took it top the office with me when I checked in to their chagrin and surpass. Word got around and later that day and the next you saw a lot of people changing how they were attached!
We used to live on moorings for months at a time, in Marathon and Westport Mass, and used them while cruising almost any chance we got. Ditto when we were out on the Pacific Coast, where there was a lot of different designs and tie up methods by region. So probably have done it a couple hundred times. We could still manage to make it "interesting" on any given day. If there is some way you can get some practice just approaching and grabbing a painter, it will really help you. For instance, Find some open water, take a ball fender with plenty of line and a weight on the end, perhaps attach a floating line of say 6 or eight feet to the eye as well and just practice both side and bow approaches and snagging the thing.
