Re: DIAMONDS, your diamond, may not be forever
Wedding ring type rings can, and have caught on a protruding object, and caused degloving of the finger, which usually leads to amputation. Engagement rings can get caught by a flying line, and pull the finger into a winch, leading to a crushed finger. Both easily avoidable. If you must wear rings on board, please go to a cooperative jeweler, and have him cut two grooves on opposite sides of the inside of the ring. The grooves must be deep enough so that if the ring is caught, it will break before dragging your finger into oblivion.
By the same token, long hair around winches and flying lines is dangerous. The hair can get caught up in the flying line, and if the line then jerks hard, a scalping injury will follow.
