Asymmetrical Spinnakers are easy to use and optimise sailing performance in light winds on courses from 75 to 165 degrees. They combine the characteristics of a reaching genoa with a spinnaker and therefore might fill a gap in your sail inventory.

The typical characteristic is a longer luff than the leech. The Tack will be fixed at the bow, anchor roller or bow sprite and is thereby flown without a spinnaker pole, hence they are much easier to handle than a symmetrical spinnaker. For this reason they are widely used on cruising boats, though they are also an important sail in a racer’s wardrobe to maximise reaching performance. When combined with a spinnaker sock the Asymmetrical Spinnaker becomes a sail that can be used by single or short-handed crews under all conditions.

Ready-Made Spinnaker

Rolly Tasker Sails ready-made Spinnakers are available in 20 different sizes. The “ready-to-sail” production gives you top quality sails at a very competitive price, available for instant delivery.
The asymmetric spinnaker, also known as gennaker, is a good choice for easier handling and good power. This sail is especially versatile and perfect for those yacht-owners who only want to have one downwind sail on board. The asymmetric spinnaker is optimized for wind-angles of 75 to 165 degrees.

Top Quality

All our ready to use sails are top quality products in keeping with Rolly Tasker Sails high standards of sail design and manufacturing specifications. Spinnakers are made in the advanced full radial cut to our demanding offshore standard construction. This means high quality cloth, durable seams, overlapping leech tapes and strong corner patches with more than ample strengthening of high load areas such as head, tack or clews. The colour scheme is standardized in an attractive blue, white and red star design.

Perfected Design

The sail designers at Rolly Tasker Sails have created a modern, asymmetric spinnaker in full radial cut. The profile is of moderate depth to make the sail suitable for all reaching and running courses. The profile is deeper in the forward part of the sail, and flowing aft in a smooth curve to ensure optimum performance and easy of use.

Choose your Sail

All our ready-made asymmetrical spinnaker come in a wide range of sizes to suit most yachts from 20 to 65 feet length. Defining the correct size for your yacht is easy, just follow the sizing chart on the link above. 

SELECTING YOUR NEW ASYMMETRICAL SPINNAKER

WHAT SIZE DO I REQUIRE?  

The luff length is the deciding factor when choosing the right size Asymmetrical Spinnaker.  As a general rule, if you are going to fly the spinnaker just above the front pulpit, then the luff length should be about the same length that the mast height is above the deck.

For a more accurate measurement, raise a tape measure up on the spinnaker halyard until it’s at the full hoist position and measure down to where you would like the tack of the spinnaker to be – we’ll call this measurement "A".  If you have a bow sprite, this would be to the end of the bow sprite.  If you don’t, it will most likely be to the top of the forward railing (pulpit).

The luff length of the spinnaker should be measurement "A" x 1.04 (give or take 300mm either way).  For example, if the A measurement is 10.00m then the luff should be 10.00 x 1.04 = 10.30 +/- 0.30 or between 10.00 and 10.60.  In referring to the sizing chart below you will see that the correct sail to choose is our #2 Asymmetrical Spinnaker which has a luff length of 10.10m.
