I finally bit the bullet and bought a 2017 TI a week ago. Tried it out the next day in a small lake nearby (Tempe Town Lake for anyone in the Phoenix, AZ area). It took a while to figure out the seats and to make sure everything else was in order before launching off a trailer. One of the AMA plugs had come out while transporting the boat... applied some electrical tape as there are no waves there. I wasn't able to set the mast while the boat was on the trailer; tried from the dock and that didn't work either. My companion (a stronger, taller male) was able to take care of that. I think part of the problem is lack of sufficient upper body strength and part is figuring out the technique. The boat is too high while on the trailer and too far in front of me from the dock.
Any tips would be appreciated.The other issue is that I had great difficulty "forgetting" all the years of tiller usage as the control on the TI is just the opposite.

Then I discovered that the 2nd knee replacement didn't flex quite enough for comfortable setting of the pedals.

That will improve over time as it has only been 7 months since that replacement. All in all I'm really happy about the boat and I'll work up to being able to handle the mast setting and removing. Summer heat is a challenge here this time of year although once on the water that wasn't a problem.
