Just a couple things to add. The 16 works best as a 1 or 2 person boat. The bows drag and it's hard to get the weight right with anything more than 3 - especially if everyone is ~200+ lbs. I bought an 18 for that reason. After sailing with some weight on the 16 and seeing it's performance drag SO much, I find the 18 much much better suited to carry the extra people and weight.
With that said, once you get the hang of it be sure to solo it yourself and have some fun at some point. The tacks require you to backwind the jib. I've never tried gybing the boat.
Is the power of 2 hulls with you?
