    Leeway coefficient

    In the Leeway calculation inside Expedition, if you check 'Leeway from heel and bsp' what coefficient is applied in the calculation of Leeway?

    Re: Leeway coefficient

    One supplementary question, the mast height value directly below the leeway cal
    If I set this to actual wind instrument height, how does that affect 'everything'?
    Does that affect the GRIB wind speed? I now have a boat with the wind instruments @ 32m above water level, so I am starting to consider the Hellemen exponent and would be factoring wind speed up by about 14%. Manual doesnt seem to talk about it?
