Just as most cat owners I started out on a monohull. I can say they both have their place, but I have grown to prefer a cat. My reasoning being that much of our time is at anchor, or hopefully off of the wind. That is the plus to a cat, and also the space.
The minus, and it is a big one. Is going to weather can be hard on the nerves, and the boat. There is a Privelege for sale in my marina just south west of Jacksonville Fl. The people just moved ashore into a condo. If you like I can get some information for you.....................
