Tragic Accident Highlights Safety Gear Shortcomings

The United Kingdoms Marine Accident Investigation Branchs report on the death of Simon Speirs highlighted several factors that contributed to Speirs death, as well as the many elements required of successful MOB rescue. The full report, documenting in great detail the events leading up to Speirs going overboard, and the eventual recovery of his body should be required reading for any offshore sailor.

  1. The board concluded that Speirs tether clip lodged under a cleat where the jackline terminated.
  2. The load on the trapped tether clip caused the clip to bend open, ultimately releasing.
  3. The lifejackets were supplied with an Ocean Signal MOB1 AIS beacon. This personal AIS beacon was activated automatically when the lifejacket was inflated and allowed rescuers to track Speirs. The AIS signal appeared in the plotter two minutes after Speirs tether released to drop him in the water.
  4. The crew employed a combination of tacks, when able to, and gybes to approach Speirs in the water.
    During one gybe the main sheet became caught around the main sheet winch and ripped off the self-tailing mechanism. Additionally, one of the blocks for the main sheet traveller broke. These factors combined to make trimming the mainsail more difficult.
  5. CV30s dan buoy was equipped with an AIS beacon rigged to activate as the buoy was thrown overboard. During Speirs MOB recovery the dan buoys AIS beacon never appeared on CV30s plotter.
