vegasvec...I barely get my trailer tires in the water or at all....I have the PVC pipes angled down via an 11 degree coupler and then using 1/4 x 20 hardware to bolt it to a 1" x 4" board I attached to the end of my Trailex trailer.
Maybe you could come up with something similar as it makes loading much easier and the PA "self aligns" as you winch it onto the cradles.
Basically, with my PA-14, I extend the winch strap aft about 8.5' and then pull the bow up onto the 11 degree angled downward PVC pipes, snap the strap clip onto a fitting I installed over the forward carrying handle....then winch it on the trailer....this photo shows the "aft" portion of my trailer set up.
Since your PA-17 would still be floating in the water, lifting the bow up should not take much energy to do this and then affix/snap on the winch strap clip....in the wind, it works fine....just ask me if it's windy in Hood River, the windsurfing and kite board capital of the US
