Let’s get the boat engines started!

Common Boating Terms

  1. AFT: The back section of the boat. Remember it this way: “A” for “After” part of the vessel. When someone says “move aft,” they want you to head toward the back of the boat.
  2. Astern: Directly behind the boat. If you’re water skiing and fall, the boat will be “astern” of your position. Think of it as the boat’s “rear-view mirror” perspective.
  3. Hull: The main body of the boat – basically, the “shell” that keeps water out and you in! Just like your body needs skin, a boat needs its hull to function.
  4. Port: The left side of the boat when facing forward. Here’s a handy tip: both “port” and “left” have four letters. This red-colored side helps other boaters navigate at night.
  5. Starboard: The right side of the boat when facing forward. Marked by green lighting at night, this term dates back to ancient ships when the steering board (star-board) was on the right side.
  6. Bow: The front of the boat. Picture it like the bow of a gift – it’s the first part that “presents” itself! When someone yells “bow watch,” they need you to look out for obstacles ahead.
  7. Cabin: The enclosed living space on a boat. Think of it as your floating bedroom, living room, or shelter from the elements. Smaller boats might have a simple cabin just for storage.
  8. Anchor: The heavy metal device that keeps your boat in place. Like a parking brake for boats, it digs into the seafloor to prevent drifting. The phrase “anchors aweigh” means the anchor’s been pulled up.
  9. Bilge: The lowest inner part of the boat where excess water collects. Nobody wants a “bilge rat” reputation – that’s someone who hangs out in the worst part of the boat!
  10. Fender: These are the “bumpers” of your boat – soft cushions hung over the side to protect your vessel when docking or rafting up with other boats.
  11. Helm: The boat’s steering control station. Just like a car has a driver’s seat, a boat has a helm. The person “at the helm” is in charge of steering.
  12. Stern: The back end of the boat. Easy to remember: Stern sounds serious, and the back of the boat has a serious job keeping the engine and providing stability.
  13. ABeam: When something is at a 90-degree angle to your boat’s side. If another boat is “abeam,” it’s directly to your left or right, like arms stretching out from your sides.
  14. Amidships: The middle section of the boat, halfway between bow and stern. When someone says “move amidships,” they want you in the center of the boat for better balance.
  15. Apparent Wind: The wind you feel while moving – a combination of true wind and the wind created by your boat’s motion. It’s why your hair might blow forward even when sailing downwind!

Boat Slang

  1. Aweigh: When the anchor is pulled up off the seafloor. “Anchors aweigh” means you’re ready to leave – not “away” like you might think!
  2. Beam: The width of your boat at its widest point. A “broad beam” means a wide boat, which usually means more stability and space.
  3. Boat Keel: The central structural backbone of the boat that runs along the bottom. Like your own spine, it provides strength and stability to the entire vessel.
  4. Windward: The direction the wind is coming from. If you’re facing into the wind, you’re facing windward. Think of it as “wind-toward.”
  5. Abaft: Another way to say “behind” or “toward the stern.” If something is “abaft the beam,” it’s between the middle and back of the boat.

Funny Boat Terms

  1. Baggywrinkle: A soft covering made of yarn used to prevent sail chafing. Yes, it’s a real term that sounds like something from a children’s book!
  2. Scuttlebutt: The nautical term for gossip or rumors, originally referring to the water barrel on ships where sailors would gather to chat.
  3. Monkey’s Fist: A decorative knot that looks like a small ball, used to add weight to a throwing line. No actual monkeys involved!
  4. Fiddlesticks: Small wooden rails around tables that prevent items from sliding off in rough seas – like tiny boating guardrails for your sandwich.

Sailboat Terms

  1. Leeward: The direction opposite to the way the wind is blowing – basically, where the wind is going. The opposite of windward.
  2. Gybe: Also spelled “jibe” – when a sailboat changes direction with the wind behind it. Can be exciting or scary depending on your experience!
  3. Tacking: Changing direction by turning the bow through the wind. Like a zigzag path when sailing against the wind.
  4. Sheet: Not a bedsheet! These are the ropes (lines) used to control the sails. “Sheet in” means to pull the sail closer to the boat.
  5. Telltales: Small pieces of ribbon or yarn attached to sails that show wind direction. Like tiny weather vanes for your sails.
  6. Companionway: The stairs or ladder leading below deck. Your companion on the way down to the cabin!
  1. Dead Reckoning: Calculating your position based on speed, time, and direction traveled from your last known location.

  4. Way: The forward movement or progress of a boat through water. “Making way” means moving forward.
  5. Chart: A map showing depths, hazards, and navigation aids. Never call it a “map” if you want to sound like a pro!

Safety and Emergency Terms
