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.

Air compressors and accessories

Kahlenberg air horns can be powered from a variety of sources including existing supplies. However if you want the same reliability and safety in service as the horn itself then specify Kahlenberg air compressors with your purchase.

Kahlenberg air compressor kits come with a comprehensive set of components all carefully matched to provide best performance. DC and AC-powered options are available.

Kahlenberg UK also stocks a complementary range of accessories and spares. Please contact us on +44 (0)1635 35 35 35 or by mailing This e-mail address is being protected from spambots. You need JavaScript enabled to view it for assistance.
