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: 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] 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.  | ||

The ship will ride higher or lower depending how much it's displacing at the time, but you would think that the draft marks would be in a permanent position. So, since the red stripe seems to change width and vertical position, who is to say my model is right or wrong other than me? | ||

Looking at the rudder, the draft marks are in the same relative position pre and post restoration but the top of the red band has gone up from mid 22-23 to mid 23-24. I assume the other pictures are of the 1844 diagrams but they don't show the rudder. | ||

Can I ask if you have heard of what used to be called the "Plimsoll Line" ? Now I think Load line comes into the discussion. It still is as confusing to me as it was when I heard about it as a kid. They have played around with it for over a century and a half. Keith. | ||

I had to look it up on Google to see what you were refering to. According to NOAA: "The Plimsoll line is a reference mark located on a ship's hull that indicates the maximum depth to which the vessel may be safely immersed when loaded with cargo. This depth varies with a ship's dimensions, type of cargo, time of year, and the water densities encountered in port and at sea." In modern time it's a complex symbol located on the side of the ship. The 1844 Draught & Lines plan shows two full length lines. The high one identified as "Load Draught When Equiped for Sea" and the lower one, "Light Draught of Water - Lower Mast and Bowspirt" I prersume the red stripe is painted between these two lines. | ||

May not be relevant for you, but here is what I have found so far from my research. However this is for British ships and not sure if it is applicable to you. The Imperial system of marking was used in mid-19th Century and employed Roman Numerals as defined in the British Weights and Measures Act 1824. When not painted on, this system had the the marking made of 1" wide metal (probably copper/bronze) Roman Numerals 6" high The top/bottom of the numerals were connected and flat along the outer edges. So the bottom of one was placed with its bottom edge on the appropriate depth at that point (measured from the bottom of the hull/keel), then subsequent marking 12" above and below ongoing as required. For British ships at least, most were coppered well above the waterline so that despite her laden depth, and the motion of waves, most of her coppered areas was within the water. The design Waterline (DWL) was therefore below the upper edge of the copper (copper line). I think from your pics, you have implemented this. Also, the first recommendations for the use of cargo loading limits based on the freeboard, were introduced by Lloyds Register in 1835, but these were only required for ships registered with them. It was not until 1876 that ships were compelled to mark their maximum draught with a diamond and horizontal line each side, and that Lloyds required some vessels to add the letters ‘LR’ to their safe loading draught. I am not sure when the more modern draught marking systems were introduced (metric, arabic numerals etc), as I did not research that for obvious reasons. So when first launched, Constitution may not have had depth markings, then had them applied as time went by during refits to meet the then current local requirement? Hope this helps? If not applicable just ignore  .cheers Pat [ Edited Sat Aug 13 2022, 01:55am ] | ||
