Dorsal Hatchet Surf SUP Longboard Surfboard Fins - Red The Dewey Weber Red Hatchet Fin was originally designed by Dewey in 1965. The original template was a massive 18 inch; was called the Turn Fin before adopting the nickname the Hatchet Fin. Once the function of the fin was set Dewey worked on a profile that would be synonymous with Dewey Weber Surfboards. In early 2000 Cory Weber asked us to recreate this template using our technology. Today we offer two sizes this fin has been used in vintage boards as well as some retro shortboards.
