Finn Class technical information - class rules, measurement guidelines, boat data and sail number policy.
These files are offered for information only and describe the current recognised practice in measuring hulls, sails and masts at regattas, and the equipment needed to achieve this. They should be read in conjunction with the current Class Rules and the World Sailing Equipment Rules of Sailing.
The technical questions sailors keep asking about - electronics, equipment and the grey areas in between. Read the thread, react and add your view.
GPS-based instruments that show heading, shift and speed are now normal kit in many fleets, and more Finn sailors are training with them every season. Where does the class draw the line between a training aid and a racing instrument, and how is it checked at events? Share what you use and what you think should be allowed.
Carbon booms, titanium fittings and one-off hardware keep appearing in the dinghy park. Are they within the spirit and the letter of the class rules, and what does it do to the cost of being competitive? Post your view, especially if you have had a measurement decision on this.
The mast is the heart of the Finn package, but the way bend and stiffness numbers are recorded and shared is patchy. What data do you keep, how do you compare masts across builders, and would an open database of measurements help the fleet?
