Yes Ashley I wandered from one subject to the other. there I can carry the boat about OK, but was just wondering if, rather than contrive something to sit it on while fitting a keel, I might be better doing that on a launching trolley. Think I just carry it and launch it with straps after fitting keel on a stool of some kind, as Richard suggests. The issue of a box is a bit more complicated. As the boat is 4 and a half foot long and (being a paddle steamer) also quite beamy/oddly shaped, the box would have to be sizeable, though I have made the mast removable, which helps. I did invest a couple of years back in a synthetic material box made by a firm in Liverpool, but it is so unwieldy I am not sure it is an improvement on simply carrying the model in and out of the car. I will post a photo, but at five foot long it is not great. I could build a wooden box, but that would I suspect be no simple task to get into the car!
