Finely found the time to get the boat off the trailer, after spending 3 weekends making up boat stands, making sure they were going to be strong enough to hold her up, and after testing for strength and stability.
Out came the trailer and into the shed for 4 days, for maintenance, replaced all wheel bearings checked braking system replaced any faulty parts also checked for any damage.
Then come the good part spray painting the whole of the trailer, firstly soaked the whole thing with a good coating of Penetrol rust treatment let stand for 24hrs, then spent another whole day spray painting the whole thing with Tectyl 506.
Once I was happy with the results it was just a matter of pushing the trailer back out of the shed, pushing trailer back under the boat, lower stands job done.
Now the best thing is I will always have the boat stands handy for my yearly maintenance and for any other reason I need to get the boat off of the trailer, it only takes ½ hour and boats off of the trailer to do whatever I need to do.
