Mark Davis, West Country Boat Transport (Launceston) has been recommended a number of times on this forum. He's bringing our 25 footer up from Plymouth to Essex on Monday for what I think is a very reasonable price.
Another satisfied customer with' Beverley Transport' of Hull,
moved two boats for me with first class service.
Try and ask if they can do a 'Backload' it will be cheaper but you may have to wait a week or so
Good luck
Mike
