I'm looking for a trolley for a Hunter 326 twin keel (not needed to be a full roadworthy trailer), a simple but robust means of winching my boat up a ramp then dragging it on to hard standing with a tractor. My sailing club supplies the winch, tractor and operators. Before I anticipate the expense of having one custom made, It's worth asking here to see if there's knowledge of one already available, preferably in the UK.
