    Re: Course to steer. Has anybody come across this little rule of thumb before?

    Tony:
    
    I haven't heard of this rule-of-thumb, but geometrically it makes a lot 
    of sense -- a 6 degree course offset will take a vessel 0.1 nm sideways 
    for every 1.0 nm of forward progress, which is what you'd need for a 
    beam current of 10% of vessel speed.   And if I work out the plot for a 
    bow or quarter current, 4 degrees is about right, too.
