Large boat trailer up to ~ 30ft

Large boat trailer , I used this to move an Elysian 27 cruiser from the Royal canal to the Grand canal by road towed by a tractor , strong steel channel construction , axles are MK1 transit axles which on a Google search can take up to 1750Kg each , there is a spare wheel , all the tyres are commercial ones, it was set up for a keelboat when I bought it the pieces are still there for that , new wheel bearings have been fitted , I have a ball hitch for it which lets you move it when unloaded with a car etc. No longer needed as boat was sold , dimensions show it could take a boat up to ~30 foot , bunks are adjustable up and down
