    Me again.
    On a side note to my Spanish Licence problem i'd like to pick your brains.
    Lets say you have a licence to 24m. Is this waterline length or LOA. I'm sure i remember reading that waterline length could be used although i now cannot find the legislation anywhere. Any licence brainiacs able to shed some light? If this guy can use waterline length his problem is solved.

    From what i understand if you have a yachtmaster ticket it allows you upto 200 tons or 24 meters waterline length. That is what was said to me when i did my ticket.

    I have never heard of waterline length as a definition of a ships length. The normal is to measure the deck over the hull where it is a closed volume. This is part of calculating the tonnage. A simplified measuring is the overall length without bowsprit, rubrails and swimplatform. The latter normally gives a higher figure.

    The IMO refers to 2 methods for measurement to determine crew qualifications and manning

    TONNES GRT.......Gross Registered Tonnes

    Length LBP.........Length Between Perpendiculars usually forward and aft collision bulkheads but sometimes they use the rudderpost or I think it's 90% of the uppermost watertight deck

    However each flag state authority may interperate this as they see fit.
