>>> Single sheet steps

We’ve seen a variety of single sheet boats, where people see what kind of boat they can build from a single sheet of plywood or the like, but this is slightly different. The plans are for a set of steps built from a single sheet of ply.

I don’t know that in boat-building you are really desperate to save wood in building a set of steps, but the overall design, with the single "foot" treads looks like something that might be neat or useful on a boat. It even has some good "included" storage areas.
