MCA issues Safety Bulletin to all mariners who use GPS equipment after 5th April

The Maritime & Coastguard Agency (MCA) has issued a special safety bulletin to all mariners that use GPS to prepare for a rollover event that will occur on 6 April 2019.

On April 6 navigation data from some older GPS systems might become inaccurate due to the ‘week number’ rollover event. 

This could cause stand-alone GPS receivers and systems using GPS chips, to produce data that is 19.7 years either in the past or future, therefore generating errors in both the GPS position and time. However, if onboard equipment has been installed after August 1999, or has regular firmware updates from the manufacturer, there should be minimal risk of an error occurring.

Abandoned Boat Action

The Club has recently had to take action regarding a motor boat which appears to have been abandoned on one of our moorings. The boat has no identifying name or mark and no SSRI number and a 'round robin' to members has not revealed the owner.

Your Committee has applied the recently adopted ‘Abandoned Boat Policy’ and has attached a notice to an offending boat demanding that the owner contacts Club forthwith.

Unauthorised occupation of our moorings prevents us from allocating the position to a member and deprives the Club of income. However we are constrained in the actions that we can take by the Torts Act 1977.

Safety Notice regarding safety harness tethers

The Marine Accident Investigation Branch (MAIB) is carrying out an investigation into the fatal man overboard accident on board the yacht CV30, which was taking part in the Clipper Round the World Yacht Race.

The yacht was on the third leg of the Clipper Round the World Yacht Race having left Cape Town on 31 Oct 2017 bound for Fremantle, Western Australia.

On 18 Nov 2017, the yacht was approximately 1,500nm from Fremantle, when a crew member fell overboard. He was attached to the yacht by his safety harness tether. The hook at the end of the tether that was clipped to a jack-line, deformed and released resulting in him becoming separated from the yacht. He was recovered unconscious onto the yacht but sadly could not be resuscitated.


The crew member was using a three-point webbing tether attached to the integral harness of his lifejacket that allowed him to clip on to the yacht with a short or long tether.
A safety issue identified during the investigation was that the hook on the end of crew member's tether had become caught under a deck cleat (see Figure 1 below), resulting in a lateral loading that was sufficient to cause the hook to distort (see Figure 2 below) and eventually release.

Both images are copyright MAIB.

The tether hook was of a conventional design and quality of build, and was commonly used by manufacturers of safety harnesses and tethers that were certified under ISO12401.
When loaded longitudinally, the tether can withstand a load of over 1 tonne. However, when loaded laterally a tether hook will deform at much less load. It is important that tether hooks remain clear of obstructions and are free to rotate to align the load longitudinally.


To prevent the strength of a safety harness tether becoming compromised in-service due to lateral loading on the tether hook, the method used to anchor the end of the tether to the vessel should be arranged to ensure that the tether hook cannot become entangled with deck fittings or other equipment.

Safety with DIY Antifouling

The RYA is concerned that the future quality and availability of antifouling paints, in particular for pleasure craft use, is in doubt due to the requirement for all biocidal products to undergo a stringent authorisation procedure under the Biocidal Products Regulation (EU) No.528/2012 (BPR).

Lobster Pots and Small Craft Safety

Count the Lobster Pots!

The RYA and Cruising Association are both campaigning about poorly marked fishing gear and lobster pots around our coasts.

The South West has a large number of poorly marked pot buoys including a number in and around the Sound. The PPSA is working with the QHM on this matter.

There is a petition on the UK Government website which closed on 12 March 2018.

The Government's response to the petition is here:
