KHM is Changing its Name

Published 10:43 on 6 May 2025

LNTM 47/25 advised all mariners that as from 1st May KHM will be changing it's name to 'Portsmouth VTS' as its call sign on Ch11,  This change has been made to align with IALA Guideline G1083 on standard nomenclature to identify and refer to a VTS.  As the transition takes place if you call on Ch11, for instance to transit between ballast pile and Gunwharf Quays and use KHM, rather than Portsmouth VTS, you will still get a response.

There are no changes to the authority responsibility or service provided by Portsmouth VTS, they still remain accountable to the King's Harbour Master.
