I am considering an older Hobie 18 that is for sale locally (1982). I have never sailed any Hobie, only been a passenger on one. Is an 18ft too big to start on for a beginner sailor? Will I have difficulty righting the boat alone? Does this boat require a two man crew? Would I be better off going with a 16ft or maybe even a 14ft to begin my sailing experience? I weigh about 155 lbs., 36 yrs old if this helps. Thank you.
