It's doable... they move Lighthouses....
The challenge will be to find a place to pull the cats out of the water
and a place to store them. You don't need cradles to sit on, just space.
The trailer does not have to be huge....find the structural points between the hulls of the boat and design the supports to touch those spots and ONLY those spots. Put rollers on the supports and a 12 volt winch
from a 4x4 on the front.
What does your 50' cat weigh???
I'm sure it weighs less than my keel
Leave it on the trailer. If you want to reuse the rig, or set it on the ground... then it gets testy....
When you get to the storage
spot, put pads on the ground, hard foam will work, secure the boat with ties to...trees, dug in anchors, whatever will hold the boat in place and roll the boat off slowly by pulling the trailer out.
Rollers and the winch
will be the key...sliding the cats on and off a trailer would not be the way I'd go...
I was anchored near a public ramp
in the Cape Fear River and cruisin' in the dink. The boats these pros were putting on and off trailers for this offshore fishing
tournament were huge!!!!!
None of the trailers could go far 'enuf into water to float the rigs on. They had rollers and winchs and pulled them on....some of the boats were 40'.
Is there a place to pull your rig out nearby?????
