I am clueless when it comes to spinnakers but the 30-foot Holman I bought recently has one in the locker (with snuffer). It hasn't been used in years so the relevant blocks etc don't exist though there is a pole on deck and a spare mast-head halyard. As the boat is a ketch none of the sails are very big. Question is, can I set it up for use when single-handing? How would I do that?
