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!).

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.


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


STEP Class Spinnaker

Performance Shape

Our newest design, released just in time for the 2016 seaon, this is the Spinnaker of choice. Designed with a fourth level of panels, the sail exhibits greater stability and shape-holding traits than the competition.  Our performance design has been proven to get you planning in lower wind-speeds, helping you push past the competition or extend your lead.

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
