25.6.2.1 A Small Commercial Vessel engaged as
a pilot boat from time to time should comply with the Code as it applies
to its duties as a small commercial vessel and, in addition, comply
with the requirements for a dedicated pilot boat which are marked
with * in Section 25.6.3.
Such a vessel should be in possession of a Small Commercial
Vessel Certificate which carries a PILOT BOAT ENDORSEMENT.
25.6.2.2 In the event that the safety rail system
required by * 22.4 of Section 25.6.3 is considered to be inappropriate
because of other measures provided to prevent persons on deck from
falling overboard (e.g. extent and height of bulwarks or rails), the
Certifying Authority should be satisfied that the provisions for the
safe movement of pilots and other persons on deck during transfers
are adequate.
