    Leeway angles
    From: Buck Godwin
    Date: 1999 Jul 20, 6:26 PM

    don't know where the table came from, but garrett gives one of the
    formulas.  he claims that leeway should be (approximately)
    proportional to the sine of the heeling angle and inversely
    proportional to the speed squared for heavy displacement boats, but
    not for light and beamy ones.  from model tests of one 12.2 meter
    (overall) boat with a variety of sail areas, the constant of
    proportionality is about 464 degree-knot**2, up to about 10 degrees of
    leeway.
    
     8 * heel / boatspeed**2  an approximation of that formula.
    
    
    if someone checks ocean navigator back issues, please check the
    following issue or two for a correction, just in case there was a
    typo.
    
    Section 3.5.3 of The Symmetry of Sailing by Ross Garrett also
    describes methods of measuring leeway.
