a lifeline routed through the Davit Pulleys: the Lower Davit Pulley (C), the Upper Davit Pulley (D), and the Rear Davit Pulley (E).

The Winch Bracket (F) secures a winch to the back of the Davit Arm.
The Davit Mast is comprised of one or two Mast Extensions (G). It is secured in place between the Davit Arm and the Davit Base.
The Davit Base is comprised of the Base Center Section (H), the Leg Sleeves (I), and the Leg Tubes (J). The Adjustable Feet (K)

provide height adjustment for the Variable Davit System and keep the system upright. The Tri-Screws (L) and Locking Pins (M)

allow for adjustment of the width of the system. The Level Indicator (N) helps the user ensure that the system is properly level.
