Thanks for all of your inputs guys. You have given me many more concerns to consider than what I initially thought about.
The idea of putting it in the water would certainly be the simplest. However, after being on the hard for 6 years, I am reluctant to trust all of the 13 thru hull fittings. (Some are even missing) I do like the method in the video, I think I will eventually try an amended version when I decide where I am going to finish the restoration.
I have a 100 Hp tractor with a front end loader. It can easily pick up the tongue of the trailer, not sure if it can lift up 1/2 of the boats weight. The boat is a 1964 Allied Seawind partially restored. The boat is real heavy, the crane that sat it on the trailer where I picked it up from estimated it at 12,000 lbs. That lift cost me $962.00 by the way. The marina where I have a slip does have a travel lift. I think they charge ~$100 per lift. I could set it on stands in their yard long enough for me to get my other boat in the water, then have them put it back on the trailer until I decide where to park it for the completion of the work. Even though the boat was essentially free, it is definitely worth the effort to finish the restoration. The boat was packed with boxes and boxes of new winches, electrical panels, throttle controls, mast head, cleats, stanchion bases, plumbing fixtures, all brand new ready to be installed. It also has all new cabinetry, and other stuff I haven't figured out exactly what its intended function is.
