I think the desire to be able to travel far and fast in a dinghy is no different than the ability to travel far & fast once ashore, but few people carry bicycles with them because they are not practical. Personally, I'd carry folding bikes before I'd carry a rigid inflatable because that fits my style and desire more closely. In the end it comes down to practicality more than desire. Sure we'd all like to travel in the Queen Mary (without the other passengers), but the reality is we travel on small boats with limits to what can be carried and with limits to what can be spent. In the end if we really wanted to travel fast we wouldn't be cruising on a sailboat...
