Great stuff to know. I also have a dirt and gravel driveway and was wondering how i was going to lift the boat for painting.

nearly 40 years.  I generally leave the trailer under
the boat while painting, for my own comfort, but she has never fallen.

The lifting system requires 2 12'-4x4s (for the "A-frame", use 16' 4x4s if
you can find them), 3 8'-4x4s (for the "Pi-frame"), 2 8'-2x6s, 2 chain hooks
w/3' of 3/8" chain to engage the lifting eyes at the stern or a 20' tow
chain w/hooks (2-ton test), 1 chain coupler (or bolt) , 5 10"-1/2" carriage
bolt/nut/washer, 4 5"-1/2" carriage bolt/nut/washer, 1 2-ton and 1 1-ton
"come along" winches.  The entire assembly can be purchased from Harbor
Freight / Home Depot for about $200.

Basically, the 2 12' (or 16') 4x4s are assembled into an "A-frame", bolted
through by a 10" bolt at the top and placed around the front of the trailer,
through or over the bow pulpit.  A cut length of the chain is looped around
the top of the "A", at the vertex, connected to the 2-T winch which is
attached to the bow lift eye (protect the bow and rub rail from damage). Add
bracing from the A-frame to the ground to stabilize.

The 3 8' 4x4s are assembled into a "Pi shape" with cross bracing using the
2x6 materials.  The ends of the tow chain are hooked into the stern lift
eyes and attached to the cross piece of the "Pi."

To lift the stern, I lower the front of the trailer to the ground and
shorten the stern chains to just connect.  Then, when I jack up the front of
the trailer, the stern "lifts" off the trailer.  Next, I lift the bow with
the come along and the A-frame and presto she is off the trailer.  The
second come along is to stabilize the stern "Pi frame" so that the lifting
frame does not shift forward (parallelogram) and settle the boat back into
the trailer, since the frames are erected slightly tilted towards the boat
(don't ask why).

I prefer to sand and paint whatever is not obscured by the bunks before
lifting, for safety. Once she is up off the trailer, I sand and paint the
area that contacts the bunks without being under the boat. Once dry, I lower
the boat and finish anything that requires touchup.

I have used the same setup to lift the boat and reposition the trailer to
achieve the correct tongue weight as well.
