I spoke extensively with an Armstrong rep and ordered a swing ladder and mounting hardware to mount the ladder to my engine bracket. The "L" piece is called a "PLM" bracket and is specifically designed for engine brackets. I both described my bracket and sent him pictures. He said it would fit my bracket. The piece attached to the "PLM" bracket with the "T" slot is the part that actually holds the ladder and allows the ladder to swing up and avoid damage if you forget to pick it up when you get underway. It is designed to put the ladder at a "stair" angle for boarding.
When I laid it on my bracket in the place I want the ladder to be, it appears the "PLM" will hang down below the water line and drag in the water. Am I crazy? Won't this create all sorts of problems with steering? I just bought the boat and have not had it in the Gulf yet. Just ran it in the bay and bayou for sea trials. Trying to get it ready to go diving. Any advice would be appreciated.
