Oxley Stabilizing Spinnakers



UK Sailmakers has become a distributor for Oxley self-stabilizing spinnaker. These unique sails have been designed for cruising sailors who are looking for extra downwind speed, but without the wild gyrations that conventional spinnakers can produce.

Stabilizing Spinnaker Explained

In contrast to a conventional Spinnaker/Gennaker, Oxley’s self-stabilizing sails BORA and LEVANTE are equipped with a lift creating wing in the upper part of the sail body.

For the long distance cruising sailor the advantages of this construction can be summarized within the following features: For the cruising sailor with an AUTOPILOT. The entire boat is stabilized as the sail is automatically balanced by the lifting function of the wing. This leads to a reduction in rudder pressure and minimized corrections of the autopilot.

Relaxed cruising can be had, even without Spinnaker pole. Besides the wide range of application, the sail offers one more important aspect: comfort. Easy to use, even under difficult conditions, the overall reduced movements in rig and boat are leading to a new feeling of harmonic long-distance cruising.

Oxley offers two versions of the stabilizing spinnaker, the Bora and the Levante. The Bora has a true three-dimensional airfoil shaped wing that inflates with wind coming through the vent, while the Levante has a foiled shaped piece of cloth that works like the flap on the trailing edge of an airplane wing. The lifting wing on both versions of the Oxley spinnaker allows these cruising spinnakers to be used in a wider range of wind angles than a conventional spinnaker, even without a spinnaker pole.

Bora vs Levante


2-D Levante Wing

Bora has a 3D airfoil-shaped wing, much like a paraglider. When it inflates, the air inside the wing becomes a soft batten that flattens the sail as pushes out to the leeches. The inflating wing becomes a soft batten. A flat sail works well for sail from dead-down-wind and flat spinnakers can be used for close reaching since rounder sails create too much heeling. Therefore, the Bora can be used for true wind angles ranging from 60-180 degrees in wind speeds from 5 to 25 knots.

The Levante can be used in lower wind ranges well since it does not have an inflating wing; it has a curved fabric wing to create lift. The Levante’s wing creates a spreading effect on the middle of the sail, but not as much as the inflatable wing on the Bora. That means that the Levante spinnaker is not as flat as the Bora. The Levante’s application range is from 70 to 180 degrees true wind angle and for windspeeds from 2-20 knots.

Which to ChoOse

Both sails work well while the autopilot is engaged because of the dampening quality of the vent and lift generating wing. The Bora approximately 10% smaller than the Levante, which makes it designed for rougher conditions. The Levante is designed for more moderate conditions as it does not need as much wind to spread the wing.

For heavy yachts, the gust dumping advantage of the Bora is not that important; these boats are so stabile in gusty condition that they can use Levante without any disadvantage. For newer boats designed to carry maximum beam all the way aft, which creates a lot of buoyancy, the Bora would be the better option.

Inflatable Dousing Sock







The INFLATABLE DOUSING SOCK from OXLEY® is the perfect solution for all kind of sail sizes and a small fore-deck hatch. A firm outer layer made of Dacron and an airtight innertube form the basis of the oval snuffer collar. 

This construction principle makes the funnel especially resilient, durable and light. This technique has its origins in the sport of kite surfing, and has been successfully in operation for a full decade. Using a double action pump or an air-compressor, the collar ring can be inflated very quickly. Using the deflation valve, the air can be released within seconds and the collar reduced to a convenient storage size.

Twin Line Dousing Sock

The Oxley Dousing Sock was especially developed for the BORA and LEVANTE. The dousing sock is separated into a bottom and top section. By pulling on the hoist rope, both sections are getting pulled up. This ensures, that the funnel does not get stuck below the sails wing.
