The bow is the front of a boat or ship — "waves broke over the bow as she turned into the swell". The stern is the back — "the name is painted on the stern". Bow rhymes with "cow", not with "low".
The core difference
These are the two ends of a vessel. The bow is the forward end, the part that cuts through the water first. The stern is the aft end, where the rudder and, on most powered boats, the engine and propeller sit. They are not synonyms or near-misses; the confusion is simply that many people never learn which is which.
How they are used
- He stood at the bow with the mooring line ready.
- Green water came over the bow in the worst of it.
- We fished off the stern all afternoon.
- The lifeboat is stowed on the stern deck.
The memory trick
Two hooks make this stick:
- Bow rhymes with prow — and the prow is unmistakably the pointed front. Both words, front end, same rhyme.
- Stern goes with aft and astern. If something is astern of you, it is behind you. Nothing is ever "abow".
The pronunciation warning
Bow in this sense rhymes with cow and now, like the bow you make when bending forward. It does not rhyme with low. The rhyming-with-low version is a different word entirely: a bow for shooting arrows, a bow in your hair, or a violin bow. Same spelling, unrelated meaning, different sound.
The related terms worth knowing
- Fore and aft: fore = towards the bow, aft = towards the stern. "Move the weight aft."
- Port and starboard: left and right as you face the bow — port is left, starboard is right. The memory hook is that port and left both have four letters.
- Beam: the widest part, roughly midway between the two ends. "A wave on the beam" hits side-on.
- Amidships: the middle.
Where people trip up
Two habits cause most errors. First, thinking of a boat like a car and calling the front the "nose" and the back the "stern" — mixing registers. Second, using bow as if it meant only the very tip; in practice the bow is the whole forward section, and the extreme point is the stem.
Note also the rowing sense: in a racing crew, "bow" is the rower nearest the front of the boat, and confusingly that person sits facing backwards. And a boat is said to be down by the stern when it sits low at the back — a description of trim, not of direction of travel.
Frequently Asked Questions
Which end of a boat is the bow?
The front. The bow is the forward section that meets the water first; the stern is the rear, where the rudder and usually the engine are.
How is bow pronounced when it means the front of a boat?
It rhymes with cow — the same sound as bowing to an audience. The bow-that-rhymes-with-low is a weapon, a hair ribbon or a violin bow, and is unrelated.
What is the difference between stern and aft?
The stern is the physical back end of the vessel; aft is a direction meaning towards the stern. You walk aft to reach the stern.
