First question short answer is yes. Based on your response, which was good but somewhat brief. With the qualifier maybe that you could do it if you are a DIY with some mechanical experience or there is good dealer locally for those odd little questions. Or there is a good, supportive local group.
I looked at a full range of boats and the 18 was a bit too big for me to handle solo. Mainly the rigging and moving the boat around. Weight is about 400 lbs. See
here. Plus it requires crew usually. If storing mast up is available, the weight thing is not so much of a prob.
Smaller boats were the attraction. I got a brother-in-law doctor in NO that I would like to get onto a cat.
I am sure all the 18 fans will swoop in and correct this post now...
