Excellent! As you know, lifejackets buy you essential time if you fall in the water, and properly clipping on your harness can prevent you from falling overboard in the first place. If your crew are doing the same, it’s good news for their safety too.
If you fall into water that is less than 15⁰C you may begin to experience cold water shock. This will drastically reduce your ability to swim, breathe and survive. Clipping onto your boat could prevent you from going overboard and wearing a lifejacket will boost your chances of staying alive until help arrives.
