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.

Latest news

Air horns now available in black and gold PVD finish

Kahlenberg has now developed a process that enables it to offer many of its air horn models in black chrome and gold physical vapour deposition (PVD) finishes.

To create these finishes a metal/ceramic compound is bonded to chrome-plated parts in a vacuum chamber. The result is a super hard, corrosion resistant surface.

The end result features the same brilliance and mirror-shine of Kahlenberg's chrome-plated air horns, with the added benefit of significantly improved corrosion and scratch resistance.

These finishes are available as standard on Kahlenberg Zero-Series, S330 and D-330 air horns, with other models on request.

Kahlenberg replating and refurbishment service

marine air horn rechrome refurbishRestore your Kahlenberg marine air horn to its original look, lustre and sound by using Kahlenberg UK Ltd’s refurbish and restoration service.

The marine environment is known for its harshness. Surface finishes are attacked by salt air and sea spray. Despite careful cleaning and polishing, finishes can eventually deteriorate to the point of needing refurbishment.

The restoration process is not just a matter of re-chroming. To ensure your Kahlenberg boat or superyacht horn is restored to its original as new state the horn is dismantled and re-manufactured in its entirety, before final testing in an anechoic chamber and the issuing a new certificate proving IMO compliance.

Brian and Dawne Dunton are the boat's very discerning owners  and they chose a set of Kahlenberg D-0A marine air horns controlled by an M-485A automatic sound signal timer in order to retrofit a sound signal that could significantly boost their presence in fog when passagemaking across the English Channel to Jersey, Guernsey and North Brittany waters. The installation was powered by a compact Kahlenberg P449-18 compressor.
