🛶 Cossack Chaika: Oar Power, Hull Resistance and Hull Speed (2D)

Side view of a long rowed boat with a row of rowers, a wake whose wavelength grows with speed and a bar showing the speed against the hull speed. Set the number of rowers, their power, the length, beam and mass of the boat, the water density and the head wind, and see the draft, the friction and wave resistance, the steady speed and the Froude number. Friction, buoyancy, the power balance and the wave relation are checked numerically, with four in-page numerical checks.
