Since there is no spinnaker pole, there is no longer need for a pole topping lift or a pole downhaul. Like a jib, the asymmetric has two sheets and no "guy". The asymmetric is simpler to gybe than a conventional spinnaker since it only requires releasing a sheet and pulling in the other one, passing the sail in front of the forestay. An ...
Like the symmetric, the asymmetrical spinnaker is often stored in a turtle, with the corners on top for easy access. While a symmetric spinnaker is flown with a "guy" and a "sheet", an asymmetric spinnaker is flown with a tackline and a "sheet." The tack attaches to the bow or (often retractable) bowsprit, and the two sheets attach to the clew.
The spinnaker pole is rigged to run from the base of the mast, [1] where there is a special fitting for attaching one end of the pole, out to windward over the side of the boat. There, one of the control lines of whichever sail it is to be used with is run through a fitting on the other end of the spinnaker pole. This allows for more precise ...
In addition, many screachers are gybed by allowing the sail to fly free and pass in front of the bolt rope and invert, much in the same way that an asymmetrical spinnaker is gybed. Tacking with a screacher may require furling and re-setting.
The jib sheet attaches to the clew of the jib, and controls it. The jib has a sheet on each side, only one of which (the leeward one) will be in use at one time. The spinnaker sheet attaches to the clew(s) of the spinnaker, if carried. A symmetrical spinnaker has two sheets, an "active" one and a "lazy" one, in the same way as a jib, but they ...
Because a spinnaker has two clews, there is always a second line identical to the afterguy attached to the leeward clew of the spinnaker. This is called the sheet and serves a slightly different function. When the boat jibes, the spinnaker pole will be moved from one side of the boat to the other, causing the sheet to become the guy and vice versa.
The sail plan consists of a Bermuda rig with a main, jib, and symmetrical spinnaker. The boat uses a retractable centreboard. An optional asymmetric spinnaker and spinnaker chute is available; also available is a "sail patch" which provides flotation for the mast in the event of a capsize (and particularly to prevent mast inversion – Turtling ...
49er with a gennaker (yellow). A gennaker is a sail that was developed around 1990. Used when sailing downwind, it is a cross between a genoa and a spinnaker.It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa.
