The essential recognition tool and study aid for the identification of vessels by lights or shapes based on the International Regulations for Preventing Collisions at Sea. This tool is designed to be used on board or in the classroom.
'What an interesting and novel teaching aid it is! It is well designed, comprehensive and easy to use. It is particularly useful to be able to see easily and quickly how light patterns change on the same vessel to reflect a change of duty, ie tugs, trawlers, dredgers, etc.'
'I do not think it would be easy to use at sea. The cover suggests that students look at the lights of a ship and then slide the panel to identify the ship. In night conditions the Light Rule would not be practical to use and this method is in any event too slow.'
'For an individual at £15 about, it is good value and would be an ideal individual learning aid to someone studying for the RYA Offshore theory or brushing up generally.'
