    Default Boom Clearance

    Does anybody know of any rules or regulations concerning the height of the boom over the deck or shear of a yacht?

    Thanks,

    Rick

    It would be a class rule

    My Shipman class has a minimum and maximum height above the mast foot.

    Cheers

    There's nothing in Recreational Craft Directive that covers boom height. I realise that this does not apply in USA but that's the nearest to a set of rules that I'm aware of.

    I should think that your height plus 6 inches would be about right !

    Plans are drawn in the sand........ at low tide.

    Default It\'s a compromise

    The higher the boom goes, the higher the center of gravity, the more the boat is going to heel.

    The lower the boom goes, the more chance of a smack on the head.

    I've got it at: me standing in the cockpit + 10cm

    (for the speedfreaks: in light winds, the boom has to go higher, lower in hard winds)
