AUDBOAT Press News – A Beginner’s Guide to Boating
“Look over there, under the gunwale,” says the skipper to a guest who needs a boat hook to help snare a mooring line. “Under the what?” the guest asks. “Over there on the starboard side, under the gunwale,” the skipper says, adding, “It’s just ahead of that cockpit stowage locker.” Obviously aggravated, the guest says, “Can you speak English, please? And what the heck does ‘mooring’ mean?”
Boating terminology can be a frustrating barrier to communication on a boat, especially between old salts and newbies. While it may appear as if the folks who use this sometimes confusing language are just speaking perplexing words to be snobby, that’s generally not the case. Trust us, knowing the vernacular is an important part of being a capable boater—it’s not some secret language boaters use to sound cool.
With that in mind we’ve assembled a basic yet comprehensive glossary to help you start down the road to boat-speak fluency. While a full account of these words could stretch on for an endless number of pages, we’ve listed the true essentials you’ll need to become a competent member of any boat crew and even sound like it.
PARTS OF A BOAT
Perhaps the most important terms you can know as a boater are the words that identify the many different parts and pieces that make up a boat. Whether you’re asking someone to shut the door to the head or secure a piece of gear in the aft locker, having a basic knowledge of the following boat terms will go a long way to advancing your nautical lingo.
Ballast: Weight added to a boat to enhance stability. “The J/24 has 950 pounds of lead ballast.”
Berth: A sleeping area on a boat. Also, a place where a boat is tied up. “We slept in the forward berth while John and Amy slept in the quarter berth” or “We keep our boat in a berth at McDoodle’s Marina.”
Bilge: The lowest section of a boat where water typically collects. “The shower sump is located in the bilge.”
Bimini: A type of folding canvas top used to shield occupants from rain and sun. “It was nice and cool in the aft cockpit under the Bimini top.”
Bow: The forward end of any boat. “John went up to the bow to lower the anchor.”
Bulkhead: Typically a transverse structural component in a boat that often supports a deck. “The aft bulkhead separates the main saloon from the engine room.”
Cabin: An enclosed and protected area on a boat. “The boat’s cabin was wide and roomy with plenty of space for relaxing out of the weather.” It can range from a small “cuddy cabin” to large living spaces with multiple rooms, which themselves may be referred to as cabins.
Cabintop: The flat or curved deck surface above an enclosed structure on a boat. “There is plenty of space up on the cabintop to stow the dinghy.”
Casting Platform: A raised, open deck on a fishing boat used for casting a fishing rod.
Chine: The part of a boat where its hull sides and bottom intersect. “The boat’s chines were sharp and angled, which gave it an aggressive look.”
Cleat: A metal or plastic fitting used to securely attach a line. “Peter tied off the fender to the starboard amidships cleat.”
Coaming: Raised edges, or sides, designed to help keep waves and water from entering a certain area of a boat. “The cockpit has an ample coaming to keep the area dry and give it a secure feeling.”
Cockpit: Any semi-enclosed, recessed area that is lower than the surrounding decks, such as the cockpit of a sailboat or a centre-console powerboat. “The cooler was stowed in the aft cockpit.”
Companionway: An entryway that provides access to the below-decks spaces on a boat. “The galley is located just below the companionway, to port.”
Console: A raised area above the deck or cockpit that occupants often sit or stand behind while the boat is underway. “John drove the boat from the helm, which is located in the starboard console.”
Deck: Essentially any exposed, flat exterior surface on a boat that people stand on. “The decks were awash with salt water after the wave crashed over them.”
Dinette: An area for dining on a boat, typically with a table set between two seating areas. “The main saloon has a huge dinette to starboard.”

Inboard Engine: An engine that is mounted inside the hull of a boat. “The boat has a 237-horsepower gasoline inboard engine.” Boats may be called inboards whether they have a straight shaft running through the hull, a stern-drive going through the, or pod drives going through the bottom of the boat.
Jib: Generally the smaller of two or more sails on a sailboat, flown forward of the mast. “Gael trimmed the jib in tight as she sailed a course against the wind.”
Jump Seats: Small, pop-up seats usually located in the aft cockpit of a powerboat. “The Everglades 243cc has twin pop-up jump seats in the aft cockpit.”
Lifelines: Cables or lines used to prevent people or gear from falling overboard. “Andrea grasped the lifelines firmly as she walked forward on the starboard deck.”

Toerail: A wood or fiberglass rail or fiddle located around the outside edge of a boat’s deck, usually situated near where the hull sides meet the deck. “The boat’s teak toerail was beautifully varnished.”
Topsides: The portion of a boat’s hull that is above the waterline. “Jenny polished the topsides to a beautiful shine.”
Transom: The aft-most section of a boat that connects the port and starboard sections of the hull. “Most people put a boat’s name on the transom, though some put it on the hull sides.”
Trim Tabs: Adjustable metal plates on a powerboat’s hull bottom or transom that help adjust the boat’s running attitude, pitch, and roll as it moves through the water. On a sailboat, a single trim tab may be located on the aft edge of the keel to help the boat steer better in certain conditions. “Jim adjusted the trim tabs to make the powerboat’s bow ride farther down in the water.”
V-Berth: A berth that is situated in the bow of a boat. “Fred took a nap in the V-berth.”
Waterline: The line around a boat’s hull where it intersects the water. “We spent all day scrubbing the boat’s waterline.”
The best way to get an idea of what a boat is designed for and how it will act in the water is to take a look at some of its key measurements and specifications. Know these terms and you’re on your way to being able to identify the key characteristics of any given boat you come across in person, or in a review or video.
Beam: The measurement of a boat’s width at its widest point.
Deadrise: The angle of a powerboat hull’s “V” shape, usually measured in degrees at the transom. “The boat has a whopping 24-degree transom deadrise, which makes it extremely capable in rough water.”
Displacement: The weight of water displaced by a boat’s hull. “The boat displaces 18,200 pounds.” A boat’s displacement is equal to its weight at any given time, with any given load.
Draft: The total distance a boat penetrates the water, from waterline to keel or appendage bottom.
Dry Weight: The weight of a boat without fuel or water onboard. “The boat has a dry weight of 3,456 pounds.”
Freeboard: The distance between a boat’s waterline and the top of its gunwales. “The boat’s high freeboard made us feel secure in the big waves.”
Length Overall: The overall length of a boat, as measured from its aft-most to forward-most appendages. Sometimes abbreviated “LOA.” “The boat had a length overall of 21 feet, five inches, from its swim platform to the bow sprit.”
Waterline Length: The length of the hull where it intersects the water, from bow to stern. Sometimes shortened to “LWL.” “The superyacht has a waterline length of 102 feet.”
