High speed fairing block anti-rotation bolt is man
Why does a high-speed fairing require an anti-rotation bolt?
Installation of the anti-rotation bolt is mandatory because a long fairing block will act like a second keel/rudder. Failure to install the anti-rotation bolt may result in the fairing block rotating while the boat is underway. The effect may be violent movement and loss of steering, which could result in serious injury or death to passengers and/or damage to the boat or other property.
