When reaching, the sail camber allows only some attached flow over the leeward side of the spinnaker. On running the spinnaker is angled for maximum drag, with the spinnaker pole at right angles to the apparent wind. The symmetric spinnaker also requires care when packing, since the three corners must be available on the top of the packing. [7]
An asymmetrical spinnaker generates more lift at larger angles of attack than a genoa, providing the boat with more power when the apparent wind speed is dropping. It can be also carried at smaller angles to the wind than a conventional spinnaker.
Barber haulers, which adjust the spinnaker/jib sheeting angle by pulling the sheet/sail inboard or outboard at right angles to the sheet. Consists of either a ring or clip on the sheet attached to cordage which is secured and adjusted via fairlead and cam cleat. [3]
Angle of attack is a function of both the craft's point of sail and how the sail is adjusted with respect to the apparent wind. ... Spinnaker set for a broad reach ...

It is also used with other sails, such as genoas and jibs , when sailing downwind with no spinnaker hoisted, sometimes using a special light spinnaker pole called a whisker pole , possible since ...
