25.5.3.1 Generally, freeboard should be assigned
in accordance with the Merchant Shipping (Load Line) Regulations 1998.
An existing non-self-propelled vessel with a valid United Kingdom
Load Line Exemption Certificate but having an assigned freeboard less
than that required by the Merchant Shipping (Load Line) Regulations
1998 should be accepted for a Small Commercial Vessel Certificate
under the same conditions given on the Exemption Certificate.
Load line marking should be applied in accordance with Section 12.2.2.2 and 12.2.3 (but see Section 25.5.3.3).
25.5.3.2 An unmanned pontoon barge on which the
freeboard deck is penetrated only by small access openings which are
closed by gasketed watertight covers should have freeboard determined
in accordance with the Merchant Shipping (Load Line) Regulations 1998
as if it was a Type "A" ship and omitting any correction for minimum
bow height. At the discretion of the Certifying Authority, having
due regard for safe voyages of the unmanned barge under conditions
which should be explicitly recorded on the Small Commercial Vessel
Certificate, the freeboard thus determined may be reduced by up to
25%.
25.5.3.3 No requirement is made for the provision
of draught marks. In order that the towing master can readily recognise
change in the condition of the tow, the towed vessel should be marked
at the forward end with one or more white bars 2000mm in length and
150mm high (or alternative marking which is clearly visible from the
towing vessel) to the satisfaction of the Certifying Authority.
