Regulation 39 - Minimum Bow Height

  (1) The bow height defined as the vertical distance at the forward perpendicular between the waterline corresponding to the assigned summer freeboard and the designed trim and the top of the exposed deck at side shall be not less than:

  • for ships below 250 metres in length,

    for ships of 250 metres and above in length,

    where
    L = is the length of the ship in metres,
    Cb = is the block coefficient which is to be taken as not less than 0.68

    or,

    for ships below 820 feet in length,

    for ships of 820 feet and above in length,

    where
    L = is the length of the ship in feet,
    Cb = is the block coefficient which is to be taken as not less than 0.68

  (2) Where the bow height required in paragraph (1) of this Regulation is obtained by sheer, the sheer shall extend for at least 15 per cent of the length of the ship measured from the forward perpendicular. Where it is obtained by fitting a superstructure, such superstructure shall extend from the stem to a point at least 0.07 L abaft the forward perpendicular, and it shall comply with the following requirements:

  • (a) for ships not over 100 metres (328 feet) in length it shall be enclosed as defined in Regulation 3 (10), and

  • (b) for ships over 100 metres (328 feet) in length it need not comply with Regulation 3 (10) but shall be fitted with closing appliances to the satisfaction of the Administration.

  (3) Ships which, to suit exceptional operational requirements, cannot meet the requirements of paragraphs (1) and (2) of this Regulation may be given special consideration by the Administration.
