The Profile:The key element! This should be selected with a great deal of care - without a high-quality profile, good fins cannot be produced! In the 1980s the good old NACA catalogue was part of the bible for fin manufacturers - the NACA 009 was used in everysituation! Between 1990 and 95 the baton was passed to the 63 010 and 6410 and real gains in performance were achieved. For the last 8 years at Select we have been producing our own profiles based on the work of EPPLER and TOM SPEER, 2 eminent experts in aerodynamics, to achieve ourbest products Why not use the raw data of these 2 sizes? |

The Materials There are a number of these: the first materials used in the 80s to make high-performance fins were of laminated polyester. This product satisfied the specifications of that period when robustness prevailed over hydrodynamic qualities. Thehydrodynamic know-how of manufacturers at that time was rather basic and making sturdy fins was a big step forward compared with the thermoplastic fins with which floats were fitted during those years! |

The Twist and FlexTwo rather barbarous words for the uninitiated. At Select we should make our excuses for not having taken the time to explain these oh-so-important terms and which summarize within them the qualities of the fin! |
