The Squall manufactured by the Chestnut Hill Boat Company, 208 Canton Street, Stoughton, MA., was originally a design drawn a long time ago by Howard J. Chapelle. The Squall is not an original Boston Whaler design. In the early 1960's Boston Whaler Fisher Pierce Company founder Dick Fisher applied for and held a patent for the foam core manufacturing process. Circa 1964, the Chestnut Hill Squall was challenged in court as a FP patent infringement. FP/BW won the legal case and gained custody of the Squall mold for what was later called the Boston Whaler Squall 9 foot sail-row-outboard dory. I retain a digital copy of the 47 page rigging instructions for the Squall 9 footer. I also have a digital copy of the 1965 Fisher Pierce ad for the Squall. Boston Whaler started production of the Squall in February 1965.
