An in-water session with 5 crew members to assess their ability to fit and use the correct safety gear, including wet-weather gear and PFDs. The participants had to jump into the water, tread water for 5 minutes, swim 50m, demonstrate the HELP procedure (floating in the featol position to conserve energy/heat) and board the CRV from the water.
