  • Bearing 25mm bore
  • Mast 25mm carbon tube
  • Gear Generator

  Other random thoughts

  • Cartridge for mast/electronics/batteries
  • Moveable mast sub-component for Center of Effort tuning

  Iteration 1:  Quick and Dirty -- Humpback's are good at going long ways efficiently during their migrations.  Maybe use that as a starting point.  Downloaded some 3d models of whales, concept to do an area rule and make hull shape similar.  Looked for research papers on hydrodynamics of cetaceans.  

  • Hydrodynamics of Dolphins
    • An indicator of streamlining is fineness ratio (max dia/length)  4.5 gives least drag and surface area for maximum volume, although only 10% drag increase in FR of 3 to 7.  
    • Dolphin body form similar to 2d airfoil NACA 66-018.  Killer whale NACA 66-026.  Both laminar flow airfoils
