Sound signal legal requirements

While 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 D-0A twin marine air horns pictured head on Kahlenberg's yacht and motorboat marine air horns are all built to extremely high quality. They offer owners and skippers two distinct advantages, a highly reliable means of complying with IMO sound signalling requirements and an aesthetically pleasing item of deck hardware with a distinctive sound that is the envy of everyone that hears it.

All Kahlenberg sound signals are tested in an in-house anechoic chamber to ensure conformance to the standards established by the International Maritime Organization (IMO) and the Collision Regulations (Colregs). ABS and MCA certificates of conformance are included in every shipment and certificates from a number of other approval bodies are also available.

Kahlenberg air horns offer the same standards from the K-Series, which can fit even small craft such as rigid inflatables (RIBs), through to larger models that can accommodate superyachts and large commercial vessels up to 75m (264ft) and beyond if required.

S-330 marine air horn

The Kahlenberg S-330 marine air horn provides a fully IMO compliant and ABS certified sound signal for leisure boats and commercial vessels up to 75m (246ft) but in a very compact and efficient package.

The size and efficiency of the S-330 is a result of detailed design effort on its special alloy diaphragm that produces the requisite levels of sound for very modest air consumption. The horn has been extensively tested and refined in Kahlenberg’s own anechoic test chamber.

The performance of the horn has subsequently been certified by ABS and you can view the model’s ABS certificate below.

As a result of this design effort the S-330 outperforms competitors in terms of its air consumption and form factor. This also leads to corresponding benefits below decks as extremely small DC or AC compressor systems and tanks can be utilised while providing ample capacity to IMO requirements for all required signals.
