Why Crosscut?

The Ullman Sails J/70 mainsail uses a crosscut panel layout to improve the sails ability to twist, ultimately making the sail easier to adjust and trim according to the conditions.  This has proven successful in many of our one design development programs, most notably with the Melges 24 Dacron “Shark” mainsail - Samuel "Shark" Kahn won the 2003 Melges 24 World Championships at age 14. (The M24 Shark mainsail also powered the 2005 and 2007 World Championship teams!).

Dacron Tri-Radial AP Race Jib

- Premium Firm Finish Square Race Dacron

- Radial Panel Design

- Zipper Luff

- Custom Tapered Battens

- Vision Window

 

Why Tri-Radial?

Performance through the Wind Range

Our tri-radial race jib is cut to take advantage of the low stretch of the Square Dacron cloth bias in an all-purpose head sail.  The result is a jib that doesn’t stretch, keeping the sail flat as the wind speed increases.


Durability

The combination of a radial panels and Square Dacron is essential give the sail the durability needed for a Dacron furling head sail.

 

AirX 650 AP Class Spinnaker

Designed to Perform

The Ullman Sails J/70 spinnaker is designed with a powerful flying shape that is easy to trim and performs across all wind angles.

Cloth Matters

The sail is built using AirX650, a preferred high performance nylon that has proven to hold its shape and firmness throughout a season on the racecourse.

Standard Features:  Spinnaker delivered with class royalty,adjustable luff, foot and leech cords, and fold bag.

Available Upgrade:  Vision Window

Ullman Sails Sail Development

All of our one design sails are developed and refined through an extensive sail testing program that involves time on the water and on the sail loft floor. The collaboration between our design team and top competitors ensures that our sails perform through the wind range, giving our customer's an edge on the racecourse.

"In one design the goal is to have an all purpose sail inventory that is powerful in light breeze and low drag in heavy air."

 - David Ullman, President and Head Designer
