International Folkboat
Description
The International Folkboat, commonly known as the IF Boat in Europe, is a timeless 26-foot fiberglass pocket cruiser and one-design racer designed by Swedish naval architect Tord Sundén as a modern evolution of the iconic wooden Nordic Folkboat. Introduced in 1967 and entering production in 1969 by Marieholm Bruk in Småland, Sweden, it was created to adapt the clinker-built wooden classic for fiberglass construction, offering enhanced durability, affordability, and global appeal while preserving the original's seaworthiness and simplicity. Over 3,000 units were built primarily by Marieholm until 1984, with licensed production in the UK, Australia, and ongoing builds by Seacamper in Germany—totaling more than 5,000 worldwide. Renowned for its long keel, narrow beam, and "big heart in a small package," it's a favorite for solo or family cruising, coastal racing, and even transoceanic voyages, embodying Scandinavian minimalism with no-frills handling that rewards skilled sailors in all conditions.
