Due to the high level of commercial and pleasure boating activity in the Great Barrier Island and Eastern Coromandel areas, as part of MSA's upgrading of coastal VHF coverage, ... produce a Marine Notice (Boats) and an MSA Circular Letter to surveyors reminding mariners and surveyors of the importance of checking and maintaining the quality and accessibility of life-saving and signalling appliances on all boats at all times, and that this be included as a requirement in the relevant rules.
