BW's Bradley workshop had a cradle in the boat dock that could turn the hull upside down for repairs. Closed now of course. Anyone know what has become of the site?
Saw this cradle in use many years ago and from what I recall it could only accommodate small workboats, have a photo somewhere - will post it if I find it.
The site is still a BW lockgate workshop, I believe they make the narrow lockgates for the whole country there, again visited it a couple of weeks ago and will try and post a picture.
Regarding bottom blacking we have painted the baseplate of Fulbourne a number of times but not recently. We used Uxbridge dry dock a couple of times which has a fairly big, but not massive, gap between the bottom of the dock and the underside of the boat.
However the best facility I know is at Debdale Marina Nr Foxton where an overhead gantry crane will lift boats onto a hardstanding onto trestles that can be at head height and its only a couple of minutes works to relocate the boat to paint at the trestle positions.
