Questionable conjecture
Paul, you seem to think that a small hard dinghy should have the same behavior as an inflatable, but whats bothersome is making others think some reputable brand is defective, as 'proven' by your assumptions about the inflatable collar. (I don't have a WB but I do have a Puffin, a sailing 8.5ft dinghy.)The first time I heard of such a hybrid dinghy was in the Pardey books, where these self-sufficient world travelers wanted a sturdy dinghy that would have the bouyancy of an inflatable in rough water, but could also sail many miles even upwind. This would enable them to take an active part in their own rescue, instead of drifting helplessly until help came. An inflatable can't do this; even rowing one is an awkward and laborious affair. They fitted a collar to their Fatty Knees dinghy, and helped popularize an innovative solution, which WB is continuing.Inflatables, meanwhile, are being improved from the other direction; a hard bottom is added to high end models to give them better characteristics under power.Inflatables have a certain lifespan and wear out. And when they leak air, good luck bailing it out and continuing. I love taking my Puffin out for a sail around the creek; in the winter when I get cabin fever I go for a row; when I cruise the Bay, it follows along fine. As a former dinghy racer (Tech class), I don't expect this size or type boat to act like a houseboat. I also don't expect an inflatable to substitute for a SOLAS liferaft.None of my comments are meant to say one type of dinghy is the best. Inflatables are fantastic gear. That doesn't mean everything else is junk.
