The ultimate application to be consistently fast with a DF95 or a DF65

The Ultimate DF95 and DF65 Tuning Diary Stop relying on memory or messy paper notes. The tuning Tool is a precision logbook designed specifically for the DF95 and DF65 restricted classes. Whether you are tuning for light-air A-Rig conditions or survival B/C-Rig breezes, this app helps you replicate your "fastest" boat setup every time.

Key Features: Rig-Specific Logging: Store separate data for A, B, C, and D rigs. Precision Tuning: Record Mast Rake, Forestay Tension, Backstay settings, and Sheet Bowsie positions. Sail Trim Notes: Log your foot depth, twist, and slot measurements. Condition Tracking: Save settings alongside wind speed (knots), water state, and location.
