All Kelsall Boats For Sale
Kelsall boat manufacturers refers to the work and legacy of British multihull designer Derek Kelsall, one of the pioneers of modern catamaran and multihull design. Rather than being a mass-production boat builder, Kelsall is best known as a designer and innovator whose name is associated with high-performance, lightweight multihull vessels.
Derek Kelsall (1933–2022) founded Kelsall Catamarans in the 1960s and became internationally recognised for advancing foam-sandwich composite construction. He developed the KSS (Kelsall Swiftsure Sandwich) building method, which allows strong, lightweight hulls to be built efficiently and is still widely respected in the marine industry today.
Kelsall designs primarily include sailing catamarans and some trimarans, typically ranging from around 32 feet to over 46 feet. These boats are known for their performance, seaworthiness, and efficient use of materials. Many Kelsall boats were custom-built by specialist yards or skilled amateur builders using Kelsall plans, rather than being produced in large commercial factories.
Today, boats bearing the Kelsall name are valued for their innovative construction, strong design heritage, and proven multihull performance.
