Sailing just got simpler with Assisted Sail Trim (AST)

AST is a very special topic: Sails metrics and computer assisted sails Trim.

Jeanneau’s exclusive ASSISTED SAIL TRIM technology delivers peace of mind and ease of handling This Jeanneau innovation, co-developed in partnership with Harken, allows to trim the sails and remotely operate the winches directly from a screen at the helm station.

Designed to ensure comfortable and easy sailing, the ASSISTED SAIL TRIM system is ideal for short-handed cruising.

100% user-friendly and intuitive, it brings numerous features to cruising in the same way as the autopilot does. 

 From Jeanneau

Jeanneau and Harken are glad to announce the launch of their exclusive innovation making sailing easier.

Result of a close collaboration between Jeanneau, leading sailboat producer, and Harken, specialized manufacturer and distributor of innovative sailboat hardware and accessories, the AST “Assisted Sail Trim” reinvents cruising and shorthanded sailing.



This collaboration has produced an advanced system to make sailing easier for families, cruisers, shorthanded crews, solo sailors, and those with limited mobility.

The system, consisting of three OEM packages, offers sensor-guided, push-button sail control.

1. The Auto Tacking base package adjusts the headsail for the new tack while you steer through the maneuver. Sensors detect wind speed and apparent wind for safety.
2. Auto Trim is the perfect complement to Auto Tacking for easy cruising. Set the initial trim, press the button to engage Auto Trim, and then let the system handle sheeting. The system monitors apparent wind for perfect trim while you relax at the helm. An integrated heel control detects gusts and limits heel to your desired setting for maximum passenger comfort.
3. The Sail Management package, which will debut in coming seasons, can hoist and douse the main or genoa. Load sensors detect jams and allow the halyard to be eased for safe operation.

All functions, as well as push-button control over each winch, are operated from a cockpit display.
Harken Rewind™ winches or Captive Reel winches allow the system to both trim and ease without manual intervention.
All packages feature full redundancy and manual backup in the event of power loss.

Jeanneau will debut the Auto Tacking and Auto Trim packages on its Sun Odyssey range under the name Assisted Sail Trim (AST).
The AST will be exclusive to Jeanneau Sun Odyssey during the 2015 season.

“It’s been a challenge to keep this project secret through years of development and on-the-water testing, but this finely-tuned system was definitely worth the wait,” says Davide Burrini, Harken International OEM Sales Manager.
“By centralizing controls, integrating wind and equipment sensors, and allowing skippers to control all sheeting from the helm, this project has the potential to revolutionize cruising and shorthanded sailing.”

Erik Stromberg, Sailboat Product Director Jeanneau said, “This project has been a very unique collaboration.It has at times been difficult to tell where our Harken partners ended and we at Jeanneau began.The result is quite an elegant system, with room to grow its capabilities built right in. Our AST will give Jeanneau owners more of the relaxation they love about sailing, with less of the sail handling and adjustments that can sometimes intrude.”
