Needed something "cheap n cheerful" for my 1/12th scale mersey.
£10 folding golf trolley secondhand off ebay and a quick knocked together wooden carry frame, thats easily unclipped from the trolley to fit in the car, the wheels unclipoff the trolley also for further compactness.
The boat is virtually 4ft long, the trolley has a wide wheelbase, so very stable, wide tyres for wet/soggy ground, not a problemo.
plus, adapt a different carry frame and its easy enough to fit another boat instead.
its not just designed for one boat only, the hull web straps easily shape to fit any hull
The boat pictures only has a single web strap securing it, this was for demo only, it will normally use 2 as a minimum.
