Definition: A long, narrow strip of timber bent and bolted longitudinally to the ribs of a vessel, to hold them in position and give rigidity to the framework.

Alright class, settle down now, let’s take a look! Today we're tackling a word that might sound a bit technical, but it's really quite important in shipbuilding. We’ve got ‘ribbon’ here, and the dictionary gives us a rather detailed definition. Let’s break it down nice and slow. (Pauses for emphasis) “A long, narrow strip of timber bent and bolted longitudinally to the ribs…of a vessel…” Now, let's unpack that a little bit. Think about a ship – a big boat! It's built with strong wooden frames called ‘ribs’. These ribs are like the backbone of the ship, holding everything together. (Gestures with hands) The 'ribbon’ is this long piece of wood, shaped and curved - bent, you see? - and then it’s attached to those ribs using bolts – strong metal fasteners. It runs along the length of the ship (that's “longitudinally”) like a ribbon tied around a package. (Rhymes slightly) "So this 'ribbon', strong and true, Helps the vessel stand for you!" The purpose is simple: it gives the whole framework – those ribs – stability and strength. It stops everything from wobbling and keeps the ship rigid and able to sail! Does that make sense? Any questions about what a ‘ribbon’ does on a ship before we move on to the next word? --- Would you like me to: Give another example of where this term might be used (beyond shipbuilding)? Explain the role of "bolts" in more detail?
