The Hunter Formula 1 is so appealing to me as a kind of crazy, fair-weather, long-legged dinghy-cruising ideal.
I watched all the YouTube Sailing Kate Louise videos in which the Australians show almost-complete rejection of conventional definitions of 'dinghy' when acquiring boats for their dinghy cruising. Most of them seem to have fixed accommodation or ballast, or both, and it's the best upgrade in dinghy cruising that I ever saw or dreamed of.
Regarding very small yachts purely as much more comfortable (and more capable) cruising dinghies, makes both genres more attractive. Nothing is less rewarding than trying to treat mini-yacht accommodation as if it were roomy and comfortable like that of a bigger boat...except perhaps, trying to rig a tent over an open dinghy in a breeze which may capsize the whole affair at 3a.m.
The only downside of the Hunter Formula One seems to be the 22ft marina berth it'll demand.
Red fox 200e - Twin dagger boards which don't take up cabin space, sits on its bum, so dries out nicely. As others have said depends on what you can tow. I have a micro 18 class boat, but it has a lifting keel a bit like a topper. weights under 750kgs so easy to tow.
