With the success of the 49er and 29er, demand has grown for a similar type of skiff for less agile sailors. Initially, Frank Bethwaite experimented with a spinnaker on a Tasar but the numbers just did not work, so a new hull and rig were designed.
The 59er came into existence in late 2000, originally as the 39er. "59er" more accurately reflects the chronological position of the boat and the fact that it's target market is older than both the 29er and 49er.
During late 2000 and most of 2001, the 59er was sailed and tested against other known classes by as wide a variety of weights and skills as have been available by the many sailors who have volunteered to sail the prototype. Frank measured and listened carefully and made adjustments all the time.
