Symmetric Spinnakers

Great for downwind

Visit our site and online store dedicated to spinnakers, code zero, furlers, and accessories, at iSpinnakers.com for much more information, client projects and more.

Symmetrical spinnakers remain the most effective sails for running dead downwind, thanks to a greater sail area, and to the spinnaker pole which offsets the sail tack to windward, well outside the wind shadow created by the main sail.

Symmetrical spinnakers have some drawbacks, of course… they require using a spinnaker pole and attendant hardware, they can be a handful if you have a smaller or family crew, and maneuvers, particularly gibing, are a little more complicated…

With a spinnaker sock, however, hoisting and retrieving a symmetrical spinnaker (almost) becomes child’s play, and is definitely within reach of a cruising/ family crew.

Our Symmetrical spinnaker is broad shouldered, with a mid girth wider than the foot girth – a design that offers a more spherical shape to maximize the projected area . With a medium draft, this design delivers a multi-purpose sail, handling broad reach to full run, with true wind angles 120 -180°, and a target wind speed of 8-15 knots.
