User Guide: Gemini Sail Vision

Athena Helm integrates intelligent camera analysis of your yacht's sails. By utilizing high-definition cameras mounted on the spreader bars, Sail Vision ensures optimal trim angles, preventing sail flutter and unnecessary friction.

Analysis Parameters​

Sail Vision continuously feeds photo frames into the companion analyzer to monitor:

  1. Leach Twist & Sail Draft Depth:

    • Compares the 3D curve of your sails against target mathematical wind lift ratios.
    • Assists in selecting correct traveler slider increments.

  2. Telltale Flutter Efficiency:

    • Identifies whether physical yarn telltales on the luff of your sails are streaming flat or fluttering wildly.
    • Tells you precisely whether to "sheet in" or "pinch up" into the wind.

  3. Fiber Stress Load Cells:

    • Integrates optional modern custom strain gauges placed inside high-modulus carbon fiber sails to flag overloaded fabric tension.

Gemini Multimodal Performance Analysis​

Using the Gemini Vision API (or shipboard offline model equivalent):

  • Click Analyze Sail Rig inside the Vision console to upload a visual snapshot of your mast.
  • The model reviews current sail shape, apparent wind speeds, traveler status, and outputs custom instructions.
  • Example Guidance: "Your leech is twisting excessively to leeward. We recommend tightening the boom vang and shifting the Genoa car lead forward by 2 holes."

Night Vision HUD​

During night operations:

  • Enable Thermal Infrared HUD Mode in the video console.
  • Assists in tracking sail drafts and spotting black wind shadows or floating logs (FLOPs) ahead in complete darkness.
