Cat -vs- Mono ?
Not much adivce i can give you i am new to boating my self. One thing i have noticed . Were i dock my boat the slips are generally not wide enough to fit mono hull boats. The one fella that owns a multi (tri) one has to pay for two slips since he takes up two slips ( the removed the center mooreing polls for him to make a 30 foot wide slip) His boat is rumored to be close to getting 20kts in a good breeze. I had considerd buying a cat or tri the added expense turned me away.
