It is called a hydraulic trailer, They also need to know how to use it. Also you have to have the stands. 6 are great with chains (going under the boat) between stands. You can get by with 4, but you can never move them if just 4.
I know Napa marina was selling sail boat stands a couple of years ago but ?
else use a crane and rigger 1K+ each way.
3rd option consider a custom trailer 10K+ or a used hyd one. = trailer sailer :) I have though of this, but not sure it is worth it??????
The mover with a Hydraulic trailer is the way to go! You also want a flat and compacted spot to work on it with lots of access (turning space) for the truck and trailer (no bumps or valleys "low boys have 4 to 6" clear on a 40' span i.e. not much over 1% grade changes. (and NO mud).
Hope this helps
