Class History

When young sailors are too big for an Optimist, but too light for a Laser, the International BYTE was designed as the perfect transitional single-hander. Designed by Ian Bruce for sailors between 105 and 165 lbs., the cat-rigged Byte is 12 feet, but comes with plenty of tools to keep it moving flat and fast. The Byte CII has been chosen for two Youth Worlds, the IOC Youth Olympic games in 2010, and will again be the boys and girls one person dinghy at the Nanjing 2014 Youth Olympic Games. The 2013 Worlds are scheduled to be in Newport, Rhode Island August 23-28, which will also be the first qualifier for the Youth Olympic Games. The North American builder is Zim Sailing.

Controls for the 12:1 vang are led to both sides of the cockpit for easy trimming. This powerful system uses a mixture of high-strength wire blocks, lightweight T18s, and small, strong 16 mm blocks.


The 4:1 double-ended system uses a 16 mm hook-in block that attaches to the clew of the sail. Two T18s—Harken’s lightest blocks ever—add purchase. Control lines are lead aft to clam cleats on either side of the foredeck and are well within reach while hiking.


The Byte CII has a mid-cockpit traveler that allows lighter weight sailors to depower the sail more easily. Two Micro traveler cars run on a low-beam Micro track. A bridle attached to the cars allows sailors to sheet the boom to the center of the cockpit without adjusting car settings on each tack. When the breeze pipes up, a short dump of each car sets the boom to the correct location every time.
