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.

New Kahlenberg D-0A air horns for Formanda

Kahlenberg D-0A air horns installed aboard FormandaKahlenberg UK Ltd director Kim Hollamby has recently fitted a set of Kahlenberg D-0A air horns to Formanda, his 1974-built motor cruiser that is nearing the end of a three-year restoration.

"Formanda still had her original air horn from the 1970s," Kim relates. "But for sure it was nowhere near compliant with the COLREGs and it sounded and looked very wrong too. The D-0As are something else again. They look superb and sound fantastic, although we have to be careful not to scare the neighbours. Being based in the naval dockyard of Portsmouth in the UK when we sound the Kahlenbergs everyone starts looking around for something altogether larger."

"Prior to installation we used these D-0As in a temporary rig to persuade a yacht club of the merits of using Kahlenberg air horns for yacht race sound signals," Kim continues. "When the club commodore heard the Kahlenbergs from nearly a mile away through treble glazed glass the decision was pretty much made on the spot."

Formanda's D-0A air horns are shortly to be connected to an M-485A Sound Signal Timer prior to the start of this season.
