I splice my own 3 strand nylon with plastic thimbles (quieter than stainless ones) into a bridle between the starboard and port D rings on a 10.5' inflatable, then tow from the center of that bridle on a painter... also 3 strand nylon. I have an 8-to-10 foot painter that I use for tying up at docks, and I add another 20(ish) foot painter end-to-end for a total of around 30 feet. That gets cleated at the transom of our sailboat, and shortened to less than 5 feet when navigating crowded harbors, or docking, etc... to reduce chances of fouling that line. Also always shorten while anchoring or any time using REVERSE (I have a Gori "Overdrive" prop that requires a burst of reverse to engage). 95% of my sailing is a couple hours, and within a mile or two of shore with the family in fairly calm seas... In those cases, I leave the outboard on (but tilted up). On the rare occasion where I anticipate sailing in seas more than 2-4 feet, or winds over 20kts, or when I'm sailing solo, and don't want another thing to "keep an eye on", I take the (6hp) outboard off, and hang it from my stern rail. The dinghy sits nice and high in the water with no outboard, so even when the painter goes slack and the dink yaws 90 degrees on a wave, it straightens out perfectly and without much strain if the motor is off. Ideally I'd take it off every time, but... it's heavy and I don't have any davits/crane/help rigged to help lift it, so I do it only when it SEEMS likely to be a worthwhile use of my energy. Some swear by floating painters, but as long as you are careful never to back up with the painter out there, nylon has some really nice traits that I like (stretch, cost, ease of splicing, UV resistant).
