I was recently asked to build a captain's staircase up to a loft in a friend's cabin. I have encountered these on boats and once in a coast cabin, but building one was a first for me. The stringers are rough sawn western red cedar, the rest is madrone. The treads are dadoed into the stringers 3/8" deep and held fast with screws from the sides. My friend wanted this to be rough, not fancy, and with screws/bolts visible, not concealed, otherwise I would have done it a little differently. No finish on anything yet when the pics were taken, and there will also be a wall mounted handrail on the right side, which was not yet installed when I took the pics.
The dominant feature of these is that the run is shorter than usual, so the treads are only half the width and alternate left/right. This allows your foot to be able to have access to the tread when coming down.
