20 The towing operation should be in the charge
of a competent towing master. Other towing personnel should be suitably
experienced and sufficient in number.
21 The tow should not proceed to sea until a satisfactory
inspection of the towing ship as well as the towage, closing and stowage
arrangements of the tow has been carried out by the towing/tug master
and, when considered to be necessary, by another competent person.
22 In special cases, where particular circumstances
or factors signify an increased risk to the tow, or where the risk
cannot be evaluated on the basis of seafaring and nautical knowledge
and experience alone, the owner or towing/tug master should apply
for survey in accordance with the guidelines of a competent organization
or authority as appropriate.
23 In the special cases referred to in 22, coastal
State authorities should be informed in advance of a tow and, after
departure, coast radio stations or coastguard should be kept informed
of the progress.
