J/105 Sailing Guide
Dacron Class Mainsails Standard Mainsail Features: Class reef, cunningham, tapered racing battens with a full top batten, Kiwi luff slides, sail numbers, telltales, draft stripes, class royalty and roll bag. AP Design
A powerful shape in light and underpowered conditions, this design also flattens for speed and pointing in medium-heavy wind conditions. This sail has been proven on the race course and is very versatile, fast, and easy to trim. Pull it in and go fast! HVY Design
This design has a flatter shape with a straighter exit for medium to extreme conditions. The sail flattens and shapes with mast bend and rig tension. The sail is specifically designed with a crosscut body and radial clew to maximize and maintain shape in the highest load areas and minimize stretch. This is the sail of choice at windy venues.
Aramid FiberPath Jib
Ullman Sails FiberPath stringing machine has been upgraded to an 8 string fiber layout. Using all Technora fibers aligned along the primary leech loads of the sail, the new yarn layout provides better strength through a wider wind range and weighs a class minimum 23 lbs!
AP Design
This design is for a range of conditions – fastest for drifting to overpowered conditions. The shape allows for an easier groove to steer to and has speed and pointing ability on demand. Also, the vertical battens on this sail keep the leech straighter longer. HVY Design
This sail is fastest in medium to extreme conditions. The design has a narrower entry angle and flatter overall shape. As a result, it will depower and change gears much easier. It also responds efficiently when the boat becomes overpowered, maintaining pointing ability and speed. This sail has proven very fast in smooth water.
Standard FiberPath Jib Features: Load mapping of primary and secondary loads, constructed with the toughest aramid fibers allowed in the J/105 class rules; vertical battens, adjustable foot and leech cords, a telltale window, telltales, draft stripes, class royalty and a roll bag.

Radial AirX 700 89 m² Class Spinnaker
Standard Features: Class royalty, taped seams, your color choice, sail numbers, and a sail bag.
AP Design
This sail is not only fast, but extremely easy to trim. Ullman spinnakers are known for their speed in almost every one design class and the J/105 is no exception. The Ullman spinnaker designs fly with more sail area than chutes from any other sailmaker – thus translating into speed when sailing tighter wind angles in light to medium wind conditions, and acceleration in medium to heavy wind conditions when sailing larger wind angles.
Update: Ullman Sails has developed a new RUN spinnaker that is dominating the fleet!
The RUN Design
This design was developed for the 2007 Lipton Cup Challenge. San Diego Yacht Club used it and never looked back, dominating the regatta. The RUN design’s extra luff shape allows the whole sail to rotate better to weather – even better than our AP Design – and lets you sail deeper, faster! This sail delivers the most actual flying sail area compared to any J/105 spinnaker from any other sailmaker.
Spinnaker Cloth Options:
AirX 700: White, Aqua Blue, Red, Royal Blue, Violet, Silver, Black, Yellow*, Green*
*Color prone to fading with UV exposure
