Jay Kantola is a multihull designer you may not of heard of. He didn't work with backyard do-it-youself builders. He liked trimarans, and specified expensive and labor intense methods. As a result few could afford to build according to his plans.
HOT BuOYS Sailing Vessel is thought to be both his largest and one of the last trimarans he designed. It incorporated decades of his experience.
This particular one took 8 years to build and over $800,000 USD in materials.
It was originally rigged with a 79ft rotating mast and Bermuda sails. She was fast. Too fast. Her builders and owners, a husband/wife team, were frequently cruising the Pacific without any other crew. They reported the rig terrified them it went so fast.
Philip Maise, her second owner, has converted her into an aft-mast rig. The new rotating wing mast is 62ft.
As part of this conversion, Maise designed both a new type of sail and specialty rigging.
