Wow RR, Great post complete with some real world data! Ya gotta love it. I have been holding off on the Turbos for my (wife's) Sport and my OB since we have so many oyster reefs around here that I frequently get swept up on them by a strong tidal current or bang up the tips of the standard fins on them at low tide. But I have to admit that it would be nice to have a little more upside potential in the speed department, and the STs should be perfect for what I want to do. I'm still using my "old school" OB Mirage Drive with the SS masts and Cotter pin assembly, so obviously it won't be a problem to do the ole switcheroo. Thanks again! Dick P.S. Here's a pic of my nemesis (one of many on the Forgotten Coast!) that is completely invisible at high tide, but all too visible as I get swept up on it at a moderate running tide! |

Brilliant! Thanks for your great review, trial data and excellent photos. Simplicity of installation too. Wow, I'm completely sold. I wonder if the new ST fins might work a little better than the Standard fins as a daggerboard when sailing (a bit wider profile at the bottom). |

Thanks for the review roadrunner! Replacement for the standards? Maybe not just yet. We still have a more durable fin in the standard one and they are easier to pedal. Now we have 3 speeds... Low gear (Standard fins) Medium gear (New ST fins) High gear (ST Turbo fins) These are sold as singles, so if you want a pair... order two. 2 each PN 81193001 = $46 |

Thanks for the report. Does anyone know of a dealer that has them in stock so I can order? Thanks |

Post subject: | Bulletin to dealers |
This information was given to dealers: Now three speeds for the MirageDrive! Choose standard, ST or ST Turbo. The new ST Fin fills the gap between standard fin and ST Turbo fin performance. This new fin uses the standard mast length making it a simpler upgrade than the ST Turbo fins. These are only sold as "singles". Simply order two of part #81193001. The new ST Fin offers a mid range of performance and resistance. Many people enjoy the ease of pedaling the standard fins, but others wanted more power! The ST Turbo fin kit (# 72065) gave us a "High gear"... now the ST Fin is giving us a medium gear. Field tests show that the ST Fin has superior performance over the standard fin yet is easier to pedal than the ST Turbo. Choose the fin that is right for you... easy, medium or fast! #81193001 Mirage ST Fin $22.95 Retail (each) |

Just got my second gear today. Going to have to wait for the winds to die down before I can try them out. |

Any thoughts on using the ST's at altitude? We now have two Mirage Tandems up at 6300 foot level (Lake Tahoe, CA) and are considering the increased performance of the ST's. But humans lose horsepower at altitude just like boat engines do. At 6000 feet an engine is down 30% on horsepower. Boats are usually high altitude propped to compensate: down pitch and diameter. Wondering if the ST's will tire-out the legs in this oxygen compromised environment? |

Properly adjusted ST fins aren't much (if any) more difficult to push than standard fins; they are more efficient though, especially at higher speeds. Fortunately our bodies are more altitude-adaptable than our engines. I wouldn't be surprised if an acclimatized person could handle Turbos quite well at altitude. Remember, Turbos aren't harder to push than STs at any given boat speed, just harder tp push at the same cadence. In other words, Turbos will give the same speed result at a slower stroke rate than with STs. |
