CBTF Co.

CBTF Co., formerly known as DynaYacht and a sister company to M Ship Co., formed when Chuck Robinson, Alberto Calderon, Bill Burns, Matt Brown and Peter Isler joined forces to create a radical new appendage design that uses a canting ballast for righting moment and two foils―one forward and one aft of the keel ― for side force and steering functions of the yacht.


This design, called Canting Ballast Twin Foil (CBTF™) technology, sprang from the "geek" design of Tom Blackaller's 1988 America's Cup Campaign, which featured a forward foil and fixed keel. CBTF Co., based in San Diego, California, developed technology to swing the keel and control the foils.

The One-Design Class Schock 40, sporting CBTF technology, was dubbed “Boat of the Year 2001” by Sailing World Magazine.
