I do wish builders would come up with better dingy solutions for the occasional dingy user. What to do about a dingy is a quandary for so many, including me. As others have said, there are no good solutions, only least bad ones. What can work is so dependent on the typical marina slips in the areas you travel, and the relative need to use one often to water the pets or only for very occasional use.
It isn't a problem unique to Rangers and Cutwaters. There are no clearly visible solutions until you move into 35+ ft trawlers with clearly defined roof deck spaces and davit cranes. Ranger does that with the new 41, but that's out of my league.
The swim platform is a big feature, as is the seat that reverses to face aft. That use is featured in the brochure pictures. But hang a dingy back there and that big feature gets killed off. You can't really cross stern lines to a dock, and that is the typical NEED in the east, certainly the Chesapeake area. Most models have great visibility aft to dock, UNTIL you totally obstruct it with a dingy. So you are left with the choices of none at all, the impractical (in the east) solution of hanging it on the swim platform davits, or bag it and stow it. With the diesel inboard models its even hard to come up with an obvious PLACE to stow it unless you are willing to devote the quarter berth to that use, and there again a key feature is killed off.
It seems to me a solution could be designed in as another alternate. Slide the propane locker toward one side or the other, to make way for a box where the top and front open up. Large enough for a bagged dingy. Organize an electrical outlet near enough to have a pump. Inflate it on the swim platform, on its side and slide it into the water.
If Fluid designed that box to fit some particular model, I'd order up that model from them in a heartbeat.
A perfect solution? Nope. Less imperfect.
On the non command bridge models a longer toy rack on the top deck could hold a Porta-Bote, but that's a lot of weight to move up and down with awkward side deck access. Not an especially safe thing to try. Some mechanical assist would be mandatory. On the command bridge models you could try hanging it beside the topside railings like some promo pictures show with a kayak, but again the occasional user would find that to be obtrusive and in the way when rarely used. Assembly in the cockpit would not likely be much fun either.
I really have not seen other manufacturers deal with this well either. Its not an issue unique to Fluid. But fix this and its one big deal item that the Fluid models could do that other alternate boats can't.
