Nets on board vessels which are not used must be stowed so that they may not readily be used in accordance with the following conditions:
(a) nets, weights and similar gear shall be disconnected from their trawl boards and towing and hauling wires and ropes,
(b) nets which are on or above deck shall be securely lashed to some part of the superstructure.
All possible measures shall be taken to indicate the nature of the relationship between the towing vessel and the vessel being towed as authorized by Rule 36, in particular by illuminating the towline.
