"With" boats are available in sizes ranging from 3.2 metre to 6 metre.  They have an unparalleled reputation for build quality, sea handling and performance.  In the 1960s Francis Wills and Bror With (the world renowned Norwegian designer) developed the most buoyant and seaworthy hull designs that still form the basis for most boats today, and the Bonwitco boat company was founded in 1967 by Francis Wills in South Devon, based upon this patented dromedile hull design.
