This water ski-tuning spreadsheet is based on the tuning log outlined in the book Fin Whispering. Keeping track of every change you make is essential to your fin-tuning craft. This log organizes your record keeping, automatically calculates fin area changes (FA∆) and the fin’s leading edge location (LE), and it highlights important numbers that differ from the previous setup.
Shipping Paused Only to the USA
The elimination of the de minimis tax exemption has added 35% to the cost of WhisperFins ($104 of tax) and the book FinWhispering ($24.48 of tax). And these taxes must be paid in full in advance—a complicated and expensive proposition. The result is Canadian postal shipments to the USA are now down by over 70%.
Fortunately, we can still ship to Canada, Europe, and to anywhere else on earth. Just contact us to get current ordering information.
With apologies and best wishes to our American friends,
Jay
