Jim, The most critical thing is to measure everything before you start. Granted, the step has subsided so you need to account for that. Measure against a known reference point.
Next, make sure you understand and make accommodation for drainage from the fore section of the boat. This may be as simple as laying a short piece of PVC pipe in the bilge before you start the job. Also consider any cable runs under the step, if any. Consider where you are going to transmit the load. The "shoulders" of the bilge should be fairly strong. The shoulders are where the hull turns downward to the bilge. Other than those two considerations, wing it! You may be able to use a car jack and 2x4's to lift the cabin roof and remove the compression post will you do the work. When I rebuilt Touche's mast step in 2000, Here's the steps I took. - Cleaned out all the old rotted wood from the original step - Sanded the shoulders to reveal clean fiberglass - Cut a piece of cardboard for the floor leaving a nice gap for drainage and cables - Formed more cardboard for the fore and aft ends - Laid in multiple layers of epoxy glass spanning between the shoulders of the bilge until it reached the proper elevation Here's pics: https://drive.google.com/open?id=1WK_x9fw5BbqbNJN1UoduAQ68AJ2UuUcu https://drive.google.com/open?id=1sxolf_U_8EDzVeLUUYghorYhe4h_nLaP Note the marks denoting locations. The top of the epoxy glass block can be seen between the step box and the lip of the sole. Pretty much a brute force solution. That block of epoxy glass will last millenia. Dennis C.
