Catalina 22 Boat Review
This boat is really better suited to lakes and bays than the ocean, and is not going to be very comfortable even for one person for more than a night or two.
You will really want to try to scrape together the money for something a little bigger and better designed and more seaworthy, if you want to spend more than a night at a time on the boat, or take it any distance.
