U-Stack Mainsail Cover Mainsail stowage system from Ullman Sails

The U-Stack is the latest in easy main handling systems now available at Ullman Sails.  The U-Stack combines the lazy jack set up with a mainsail cover in one allowing you to lower your main and just zip the cover up without having to line up anything.  This system has been tested and successfully used on blue water cruisers.  The U-Stack is available in any Sunbrella color to match your existing canvas. 

The U-Stack utilizes long battens in the top of the cover that the jack lines connect to.  It also has a zipper with a lanyard for easy sealing of the top of the cover once the main is lowered.  There is no need to remove the cover when you want to raise the main just unzip the cover, raise the main and go sailing.

Priced at $75.00 per foot or $95.00 per foot installed.

Contact Ullman Sails at or  for more information.
