In case anyone is following where I am in the practicum, it’s Chapter 9.1.5. I skipped Chapter 7 for the time being. In any case, this the part where the practicum adds the “iron red” (plans state “red lead”) waterline stripe. According to the Model Shipway plans, the stripe is “not an historic feature.” By this statement, I assume it was added in the twentieth century. But since this is a US Navy commissioned ship (oldest commissioned ship still floating in the world by the way), anything the US Navy does to the ship is, by definition, historic. Here is a blurb from the USS Constitution Museum newsletter from 2017:
As most of us Conny builders know, this ship has been constantly modified. The red waterline is no different than painting the ship white with a red gun stripe like a hospital ship. So yes, I’m adding the “historic” red waterline.
To make things a tad more interesting (read more complicated), the Model Shipway plans show the red stripe between draft marks just about mark 21’ to the top of mark 18’, which at scale is ½” wide. There are photos to show this is correct …aaaannnnd photos to show this to be wrong. The composite image below shows multiple locations for the top and bottoms of the red waterline stripe - top of draft mark: 23’, below the mark 23’, and top of mark 21; the bottom locations at just above mark 18’ and below mark 20’. ‘When the ship is floating, the actual water line on the boat is at mark 19 and just above 21’. Since there doesn’t seem to be a definitive position for the red waterline, when in doubt, follow the plan, in this case the MS plan which appear to follow the US Navy 1844 Draught & Lines plan #11249 which shows the high and low draught range.

In her early years, the ship’s hull sported a yellow ochre-colored gun streak/stripe. Her familiar black and white hull color was established by at least 1811. Interestingly, Captain Charles Stewart had the gun stripe re-painted yellow in 1814, likely in an attempt to disguise Constitution and trick the Royal Navy into thinking she was another British warship in the War of 1812.
In 1842, the Board of Naval Commissioners decreed that U.S. Navy vessels were to have black hulls and white gun streaks/stripes. For the rest of her active career, until her last sail in 1881, Constitution‘s hull color changed only once, when, according to ship’s carpenter Henry George Thomas in 1844,
“December 20…Since leaving Rio, the ship has been painted white or lead color with a red streak, in place of black with a white streak…the ship is cooler…both inside and out…” [Around the World in Old Ironsides, The Voyage of the USS Constitution, 1844-1846 by Henry George Thomas]
