Nessy's trailer has been out of action for some time as I tried to get the wheels off to repack the bearings. I had convinced myself that it would be perfectly OK to launch the boat directly off the trailer as long as I never immersed the bearings in salt water.
So the wheel nuts corroded onto the studs, and nothing I or the mechanic could do would get them undone. One of the hubs had to be replaced.
I have now sworn the trailer will never see salt water again, and Nessy will be launched on a dolly in future.
Unfortunately, the very expensive dolly I bought to launch Snarleyow with did not fit under Nessy - the wheels fouled the longitudinal skegs under the boat.
So I constructed a new dolly out of bits of wood that fell off a freighter and washed up in Bracklesham Bay a while back, plus a length of aluminium tubing and the wheels from the original dolly. And a clamcleat to hold the rope over the boat.
I'm rather proud of it. Total cost: £12.
