12.2.4.1 The freeboard of an inflatable boat or
boat fitted with a buoyant collar should be not less than 300mm measured
from the upper surface of the buoyancy tubes and not less than 250mm
at the lowest part of the transom with all its equipment, fuel, cargo,
activity related equipment (e.g. diving equipment) and the number
of persons for which it is to be certificated onboard, with the boat
re-trimmed as necessary to represent a normal operating condition,
and with the drainage socks (if fitted) tied up.
12.2.4.2 A freeboard mark is not required. The
minimum freeboards recorded during the tests of Section 12.2.4.1 and
the permissible maximum weight which can be carried should be recorded
on the certificate for the vessel.
12.2.4.3 For boats operating in Area Category
6 only, which do not meet the freeboard requirement of Section 12.2.4.1
at the transom, may still be accepted by the Certifying Authority
provided it can be demonstrated that the boat is self-draining when
moving ahead, and has a substantial reserve of buoyancy. The Certifying
Authority should record such an acceptance in its report for the vessel
(report form SCV2).
