Hi Garry,
I've got the 2009 model of the same boat and I love it as well. But like you, me and the missus struggled with getting it on the trailer. Looking at the trailer in the other thread you have rollers rather than the skids I have on mine. I'm not sure what difference that makes but we found getting the keel onto the center roller very tricky for a couple of reasons.
Firstly the steering wheel being on one side meant that the boat would fall to one side as it came out of the water and would tend to steer off the center rollers, the answer was to stand in the center of the boat while driving it up.
Secondly the other big problem we found was the way the rear skids were set with the center roller to "guide" the boat keel to the center roller. The roller that was fitted had too large a diameter, so when the keel ran down the skid it would jam against the outside of the roller rather than dropping into the center of the roller.(In the photo you can see the new roller in place, and get an idea of how the skid guides the keel to the center.) Took us a year to figure this one out, changed the roller and now the boat finds the center every time, and with a bit of practice we can now drive the boat up most of the way, before the winch takes over.
Hope that makes sense, anyway, you should get lots of enjoyment out of your rig once you figure out getting it on and off(like what the other blokes said, pick a day when no one is around and spend and hour practicing getting it on and off.
