Re: CS 30 - basic info needed
Sailing with just the jib is a fine solution on boats with smaller mains. In addition to it being more convenient to simply unfurl the jib and go than to raise the main, on these boats the jib gives more drive than the main and may be necessary to retain good control. The only caveat is to anticipate and manage the resulting lee helm, in particular you need to ensure good momentum before going into a tack as it is easy to stall the boat. I never found jib-only sailing on my CS36T a problem, whereas the boat would only go downwind under main alone.
The CS 30 is a sweet racer-cruiser, fine for coastal use, but you might lookup the story the story of the crew that raced one half-way to Bermuda before they got off...
Certified...in several regards...
