Man-overboard-system a lifebuoy and 30m of floating line. The storage bag can easily without tools be clipped to the pushpit. The lifebuoy is fitted with eight retro-reflective patches, all round grab handles and two strong eyes to hoist the distressed back on board.
The buoyancy of a lifejacket is measured in the Newton unit. A lifejacket must have sufficient buoyancy to keep the user's airways above the surface. The vests are divided into different classes depending on the amount of buoyancy, though the actual Newton's number may vary depending on the size of the vest.
