    Re: Cross-tide strategy (was: DR plotting techniques)

    As the question was given:
     <>You are in a boat capable of 4 knots intending to cross a wide river.   Your
    >destination is straight across the river.   In the centre of the river the
    >current runs at 7 knots but close inshore on either side it reduces to 2
    >knots.   What should be your strategy for crossing the river?>
     The correct answer is simply to cross directly from bank to bank. Yes, the 
    current will offset you sideways down the river.
    But that is immaterial, the question simply asks you to CROSS not to cross to any particular point.
