This is a 16 foot long double stack box trailer. Similar to the Mersea box trailers. The frame is adjustable to fit a range of different dinghies. We used it for transporting ILCAs and all of their kit. The previous owner used it for transporting 29ers. The axels were recently regreased and the frame gone over by our local mechanic. I replaced the top hatches to the box with aluminium plates to give them added strength. It also comes with a mast rest (we didn't need it for the ILCAs.) and there is a trailer hitch on the rear for carrying a bike rack. Selling as the sailor has recently moved to the US and we have returned the boats to their owners.
