SATELLITE NAVIGATION – Most of us have used regular “satellite navigation” before – it uses radio transmissions from satellites. However, the automatic equipment on board a vessel is a bit more complex and sophisticated.
SCUPPERS – Have you ever noticed holes in the deck, toe rail, or in the bulwarks, that let water drain off? Well, these are called “scuppers.”
SEA COCK – A “sea cock” is a valve in the hull where a pipe comes through. It can be turned off when not in use.
SEAMANSHIP – When you describe all the skills of boat handling, this is called “seamanship.” It could include maintenance, repairs, piloting, sail handling, marlinespike work, and rigging.
SEA ROOM – Despite what you might think, it’s not a room in a vessel. It’s actually used to describe a safe distance from the shore or other hazards.
SEAWORTHY – If a vessel can sail safely in rough weather, then she’s “seaworthy.”
SECURE – We think you can probably guess this one! When something is “secure,” then it’s tied safely.
SET – When the current is flowing toward a particular direction, this is “set.”
SLACK – You can probably guess this one. Something is “slack” when it’s loose or not fastened.
SOLEBOARDS/COCKPIT GRATINGS – You can probably guess this one. You stand on the “floorboards” in the cockpit.
SOUNDING – Surprisingly, this is nothing to do with noise. In fact, “sounding” is a measurement of the depth of water.
SPRING LINE – This is a rope (“line”) that stops a boat from moving forward or backward while being made fast to a dock. Pretty useful, we think. It can also be used during docking and undocking.
SQUALL – Get your wet weather gear (“oilies”) ready. A “squall” is a sudden, violent wind that often brings rain.
SQUARE-RIG – Imagine the biggest Tall Ships… these are “square-rigged.” It means the majority of sails are at right angles to the length of the vessel.
STANDING PART – The “standing part” of a rope (“line”) which can be made “fast.” In other words, not a loop (“bight”) or the end of the rope.
STAND-ON VESSEL – A “stand-on vessel” should not have to keep out of the way of others. Everyone else should give way.
STARBOARD – When you’re looking forward, “starboard” is the right side of a vessel.
STEM – The very front of the vessel.
STERN – Put simply, the back of the vessel.
STERN LINE – This is a rope (“line”) leading from the back (“stern”) of the vessel.
STOW – We could do with “stowing” some things around the Sail On Board office. It means that you’ve put an item in its proper place.
