Old fashioned method might be the go. If you can get the boat and trailer
into the garage, use blocks / jacks / levers to lift it off the trailer.
Then you progressively ( i.e. slowly) move the trailer out of the garage a
few inches at a time, swapping the supports around as it goes. Eventually
you have the boat sitting on blocks in the garage, with tyres or chocks
stopping it rolling sideways. It takes a little while, and having a few
extra people helps, but I suspect the time is less than building the
trolley.
Once it's on blocks, it's easy to move small distances - again, levers,
blocks, jacks. Hydraulic jacks sound good, but I'd back three people, a long
piece of 4 x 4 hardwood, and lots of assorted packers / blocks against
hydraulic jacks anytime.
