Strake Terminology

Leave a reply

I do realize there is a whole other numbering convention for Strakes, but I just went with my own instead. It gets too confusing for me using Letters. 🤔🙄😲

Terminology

In boat and ship construction, strakes immediately adjacent to either side of the keel are known as the garboard strakes or A strakes. The next two are the first broad or B strake and second broad or C strake. Working upward come the bottom strakes, lowers, bilge strakes, topside strakes, and uppers also named sequentially as the D strake, E strake, etc. The uppermost along the topsides is called the sheer strake. Strakes are joined to the stem by their hood ends.

A rubbing strake was traditionally built in just below a carvel sheer strake. It was much less broad but thicker than other strakes so that it projected and took any rubbing against piers or other boats when the boat was in use. In clinker boats, the rubbing strake was applied to the outside of the sheer strake. Many current pleasure craft reflect this history in that they have a mechanically attached (and therefore replaceable) rub rail at the location formerly occupied by a rubbing strake, often doubling to cover the joint between a GRP hull and its innerliner. Inflatable dinghies and RIBs usually have a rubbing strake (typically a glued-on rubber extrusion) at the edge.

A “stealer” is a short strake employed to reduce the width of plank required where the girth of the hull increases or to accommodate a tuck in the shape. It is commonly employed in carvel and iron/steel shipbuilding, but very few clinker craft use them.

Different Parts of the Decks on Sailing Ships

A ship has a number of different types of decks which are located at different levels and places on the ship. Needless to say, every seafarer working on a ship should be aware of these decks.

Moreover, as there are various names to a generalised concept, it’s necessary for sailors to understand what each deck name and interpretation entails.

1. Poop Deck: Originating from the Latin term for a vessel’s stern-side – Puppis – the poop deck is located on the vessel’s stern. The poop deck is basically used by the vessel’s commanding superiors to observe the work and navigational proceedings. Technically, it is the deck that forms the roof of a cabin built in the aft part of the superstructure of the ship.

2. Main Deck: As the name suggests, the main deck is the primary deck in any vessel. The main deck however is not the topmost deck in a vessel which is referred to as the weather deck. On sailing warships it is usually the deck below the upper deck.

3. Upper Deck: The deck that covers the hull of the vessel from its fore to its aft is the upper deck. It is the topmost deck on a ship. In all vessels, the upper deck is the biggest deck amongst all other decks.

4. Lower Deck: The deck located below the primary or main deck is the lower deck. Generally the lower deck comprises of more than one deck. It is just next to the lowest or orlop deck.

5. Promenade Deck: Promenade refers to taking a lazy stroll in a feasible place like a beach or a park. In a vessel, the promenade deck serves as a place for the voyagers to take a calming and enjoyable walk on the ship, while enjoying the beauty of the oceanic vista. It is generally the area around the superstructure. It can have open railings or can be enclosed in a glass.

6. Tween Deck:  ‘’tween’ is a colloquial abridging of the word ‘between.’ In a ship, the tween deck actually means an empty space separating or between (tween) two other decks in the hull of a vessel.

7. Flush Deck: The deck that extends without any constructional breaks from the frontal part of the ship to the aft is referred to as the flush deck. On such decks there is no raised forecastle or lowered quarterdeck.

8. Weather Deck: A deck that is not roofed and thus is open to the ever-changing weather conditions of the sea is referred to as the weather deck. It is the uppermost deck on the ship which is exposed to the environment.
