I've been an owner of an N20 for a long time. Seems like you are getting a mixed message here. Do not buy this boat to singlehand. This boat is way to powerful for singlehanding. It is twitchy as hell when you singlehand it. Getting it up on the beach by yourself is almost impossible unless you have the perfect hardpacked flat beach with no incline. Me and my crew have stuggled many times trying to get it back on the beach after a long day of sailing. The boat is very hard to right singlehanded with the carbon mast but it can be done in howling conditions.

If you don't have a lot of experience with cats this might not be the boat for you.

PS. If you don't buy it would you mind passing along the seller to me.
