The reason I suggested Sherry's object discription might be a ramp was her placement: "midships (proper: amidships) to 01 level." As you know, "amidships" is the center of the ship. LST's have their superstructures on the aft approximate 1/3 of the ship. If her object questioned referred to a ladder, as you suggest, this would be a really long ladder with an angle that would define it as more of a ramp than a ladder. The whole question could be resolved by indicating exactly where the object began and ended, such as: "on the main deck, alongside the superstructure, reaching to the 01 level."
