Ron B Posted January 12, 2022 Share #1 Posted January 12, 2022 Can anyone explain why the waterways are above the deck.....wouldn't that serve to prevent water running out the scuppers efficiently? Ron B Quote Link to comment Share on other sites More sharing options...
Jim Lad Posted January 12, 2022 Share #2 Posted January 12, 2022 Ron, I assume that you're talking about wooden ships. The waterway actually guides any small amounts of water along the deck and the scuppers run through the waterway at deck level and take the water outboard. On an iron or steel built ship with wooden decks the wooden deck sits on top of the metal deck nd the waterway is a form of gutter along the edge formed by the outer edge of the deck plates.

wefalck Posted January 12, 2022 Share #5 Posted January 12, 2022 There are different profiles and the waterways may actually be composed of several pieces of wood in cases. The basic objective is to turn what would be an acute angle between the deck and bulwark into an obtuse angle. Acute angles would collect water, which then can lead to rot. The same logic applies to iron- or steel-ships. Here the gutter is formed often by two angle-irons running along the edge of the deck at some distance apart. One angle buts against the bulwark, the other forms a frame for the wooden deck (as noted above). The space between the angle irons typically is filled with cement to form a rounded gutter. This also prevent water from collecting in the corners of the angle-irons. jud and mtaylor 2 Quote wefalck panta rhei - Everything is in flux Link to comment Share on other sites More sharing options...
Jim Lad Posted January 12, 2022 Share #6 Posted January 12, 2022 Wefalck, do you have an example of the 'rounded' waterway on a steel built ship? I've never seen it. John mtaylor 1 Quote Link to comment Share on other sites More sharing options...

However, it is mentioned in the text at several places. druxey and mtaylor 2 Quote wefalck panta rhei - Everything is in flux Link to comment Share on other sites More sharing options...
