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 unveils the new S-330 at Seawork

Kahlenberg S-330 boat air hornKahlenberg UK is pleased to announce the launch of the new S-330 single trumpet marine air horn at Seawork International 2011.

The Kahlenberg S-330 was developed by Kahlenberg Industries to provide a fully IMO compliant sound signal in an economic and compact package suitable for use on vessels up to 75m (246ft). This is an addition rather than a replacement for any of the models in the Chimetone range and provides operators and owners with a budget efficient option while still enjoying all of Kahlenberg's usual reliability and quality. To-date selecting price sensitive products in this area from other manufacturers has often meant choosing sound signals that are either unreliable, or not compliant with IMO ColReg requirements; the S-330 addresses those issues.

The S-330 has just received its ABS type approval certificate and one of the first examples will be on display on the Kahlenberg UK stand B111 at Seawork International.

To obtain further details please visit our stand or look at the Kahlenberg S-330 marine air horn product page.
