  • Page 3: Getting Started

    GETTING STARTED There are 8 rules that apply to the installation of these davits to your boat. These are Bill’s Rules. Please adhere to them. Rule violations are dealt with quickly. One violation mandates one week in Minnesota, in January. Two violations require two weeks in January. Three or more violations and you will have to sell your boat and buy a motor home.
  • Page 4 the stern rail that the davits are attached to is not straight, then the plastic divider will need to be sanded. Use a disc sander and sand a 1” wide path on one side of the plastic disc. Place the sanded side to the davit arm.
  • Page 5 outside of the hull or the bow eye if the boat is a rib and the other end to the other eye nut. Again, tighten using the ratchet. Stabilizer bars will not prevent the load (boat) from swinging or moving. They will only prevent the davits from rotating.
