    Default Rules question-knotmeter

    about the knotmeter requirement...

    Does the speed function on a GPS suffice, or is a knotmeter with a through-hull paddlewheel, required?

    Rule 3.17 states "A boat shall have a knot meter"

    You don't necessarily need a thru-hull.
    Mounting a paddlewheel to an L-bracket from the transom would work.
    Or use a taffrail log.

    I heard a tale of one clever skipper presenting an orange with the formula distance divided by time written upon it.
    Surfing at 10 to 15 knots that orange is going by pretty quickly.

    With an iPad, iPhone, handheld vhf, and the mounted vhf aboard Nightmare all displaying SOG , one would think a knot meter superfluous.
    Probably comes from fear of the GPS system failing. Then you would need it for dead reckoning.

    Although, if the entire electrical system failed that orange would be pretty handy.

    which has the added attraction that I can bring it home and use it on the Piper, in case I ever care how fast I'm going on the Piper....highly unlikely.
