Sound signal legal requirements

IMO COLREGs bookWhile countries across Europe will have local laws that apply to ship and boat navigation, there is a common requirement worldwide for all leisure, commercial and military vessels to conform to the IMO International Regulations for Preventing Collisions at Sea. As Steve Austin, Senior Policy Lead at the UK Maritime & Coastguard Agency (MCA) explains: "The COLREGs apply to all vessels, there is no differentiation between coded and non-coded vessels. Should the whistles prove not to conform then they will need to be modified or changed."

"Whistles should conform to the performance in COLREGs, Appendix III and the appropriate parts of IEC 60945 to EN60945 which deal with the marine operating environment."

All Kahlenberg products meet or exceed these requirements. Many other new and currently installed sound signals are non-compliant and might be breaching maritime law and invalidating insurance cover.

Kahlenberg at the Southampton Boat Show

PSP Southampton Boat ShowKahlenberg UK will be showing many of the popular models in the Kahlenberg range of marine air horns, sound signal controllers and accessories at the Southampton Boat Show in September.

Visitors to our stand G077 in Ocean Hall will also be able to get great advice on the importance of sound signals on any boat along with practical information on how to fit models in the range and details of auto-controllers that leave you free to concentrate on your watch-keeping when bad visibility hits.

Among the sound signals on show will be the ultra-compact K-Series marine air horns, the single, dual and triple trumpet Kahlenberg Zero Series marine air horns and larger models in the range.

Do please come along to stand G077 to say hello to Piers and Toby du Pré. The Southampton Boat Show runs from 14-23 September.
