We believe every day’s a school day on a boat! That’s why we built Nautical Know-How, dedicated to answering your questions. Even better, if it can’t answer your question immediately, you can request it, and we’ll add it to our knowledge base.
Understanding the language of the marine world is like trying to learn a pirate’s secret code while juggling fish. You’ll wonder why a “sheet” isn’t something you sleep under but a rope that controls a sail. “Bowsprit” sounds like a sneeze, “booby hatch” isn’t a bird’s hideout, and “port” doesn’t come in a glass—it’s just left. If someone yells, “Man overboard!” don’t ask which direction they swam. And heaven help you if you think “scuttlebutt” is gossip—well, actually, you’d be right about that one. By the time you’ve figured out that “head” means toilet and “galley” isn’t an alley with gourds, you’ve already been hit with a wave and lost your hat to the wind they call a “nor’easter.”
Let us explain why a sheet isn’t for your bed, why “heave ho” doesn’t mean throw up (most of the time), and why “dead reckoning” is surprisingly less ominous than it sounds.
A compact transparent chartwork tool combining straight edges, a rotating compass rose and distance scales. It is used to plot or measure courses and bearings on training and nautical charts without a separate parallel ruler and protractor. The rose is aligned with a chart meridian before the edge is used along the required line. Distance…
A pivoted mounting that allows supported equipment to remain approximately level as a vessel heels or pitches. One or more pivot axes let a compass bowl, stove, lamp or instrument rotate relative to its frame. A two-axis arrangement can compensate for motion in two directions within its travel limits. Gimbals do not cancel acceleration and…
A lightweight downwind sail with mirror-image luff and leech edges, normally flown with a spinnaker pole. Either lower corner can act as tack or clew as the pole changes sides during a gybe. A halyard supports the head, while sheets and guys control the corners and pole position. It is primarily used on broad reaches…
The apparent deflection of motion relative to a rotating reference frame, including Earth. On Earth, freely moving air and water are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The effect is zero at the equator and increases with latitude and speed. It strongly influences large-scale winds,…
A vessel’s speed relative to the water immediately around it. A water log may measure STW from paddlewheel, electromagnetic, ultrasonic or pressure-based sensing. It differs from speed over the ground, which includes the effect of tidal stream or current and is normally derived from GNSS. Local flow around the hull, fouling, bubbles, heel and calibration…
