Before drilling, assemble rails onto ¼” pins putting nylon washers in between rails. Center davit onto the platform. Make sure to hold around 36” (minimum) from center of the davit to the back of the boat, keeping some of the foot on the platform for support.
Before drilling with the ¼” drill, maintain a gap (about the same as the nylon washers at the black arrows) Drill through the platform at the red arrows with the ¼” drill. We recommend using stainless bolts through the platform.
