HI Edward, welcome to sailing and welcome to thebeachcats.com, your source for all sailing questions.
It is my experience that people are in 'love' with the idea of sailing, for many different reasons, perhaps it is the sense of freedom that sailing promotes, I don't know. I can tell you this, there are 2 types of sailing, leisurely sailing and extreme sailing. you have to decide which one suits you. Leisurely sailing entails walking down to the dock with an icebox full of goodies, hopping aboard your monohull with the family, starting the motor up, putter out into the deep water, and raising sail for a nice leisurely day of cruising around the bay. Extreme sailing entails all sorts of safety gear, hauling your catamaran down to the water, setting up, checking wind direction, wind speed, sailing out to deep water and screaming across the bay as fast as you can go.
Your decision would take into consideration many factors that I'm sure other sailors here will fill in, geographical location, access to water, physical fitness, health and of course you need for 'thrill factor'. Monohulls are much slower than multihulls but have the benefit of a weighted keel to compensate for the push on the sail, not to mention some have a galley, head, sleeping births, etc, depending on length. Multihulls have a tramp stretched between 2 (or more) hulls and one sits on the tramp, to compensate for push on the sail, you use your body weight out on a trapeze wire, requires physical exertion most of the time sailing, cramped sitting position and very little clearance between boom and head. But the thrill factor is intense, nothing like zipping across the water, trapped out on the side of your catamaran, doing about 15-20 mph.
There are many other factors not mentioned in above post, too many for me to include, but I'll leave that up to other sailors. I know that all the forthcoming info will help you make an educated decision based on your personal circumstances. A good source for used sailboats is craigslist, use www.searchtempest.com to search all of the CL database, as well as this website for multihulls.
Happy Sailing
