Too late for before pics, I have demolished the Teak two-tread stair and also the old Teak ladder to the flybridge. The new stair will be mounted on bronze clips on the bulkhead and barrel bolts into the sole just like the existing was. The new stair will be at 45 deg and have three treads, while the existing was at 60 deg. The third tread will be glued up out of the treads salvaged from the flybridge. Sloth and fiscal reticence will have me filling the old dadoes with scrap Teak and I'll cut new dadoes on the 'horses'.
Pics will follow. Below is a .pdf of the AutoCAD drawing. The left (top) bit shows that the new 'horses' can be cut from the existing 'horses'. The middle bit is a cross section of the new stair, and through the corridor showing the salon to the left, the forepeak to the right and a bit of one of the doors to a berth. The right bit is a similar cross section and the existing stair. The circle and upper angled line shows that the headroom was inadequate by residential design standards and will remain so. (Irksome that I cannot rotate the .pdf, sorry!)
