Kayak Building Terms (Terms not all specific to Kayaks)
BEAD AND COVE - A wood strip with a grove on one edge and a tongue on the other edge which allows them to fit snugly together.
BODY PLAN PROFILE - Looking at the kayak from the front.
BRIGHT WORK - A term used to describe wood that is finished natural, using varnish or other clear coating.
BUTTOCKS - Lines that cut the hull around a vertical plane parallel to the centerline. They describe how the kayak shape changes from center to edge.
CENTER LINE - A line running fore and aft equidistant from the port and star board sides.
CHINE - The corner or curve running along the length, fore to aft, of the hull where it changes from the sides to the bottom. A "soft" chine is rounded while a "hard" chine is angular.
EPOXY - A combination of resin and hardener used to cover fiber glass or made glue.
FIBERGLASS CLOTH - Filaments of glass that are twisted into thread then woven into cloth.
FORM OR SECTION - A spacer on the strong back that the wood strips are bent around to help develop the shape of the kayak.
FREEBOARD - The vertical distance measured on a boat's side from the waterline to the upper side of the deck.
FAIR - Describes a curving line that is smooth without any unnatural distortions, lumps, hooks or hollows.
GLASS - Abbreviation for fiberglass.
KEEL - The very bottom center line of a kayak.
LAMINATE - To glue two or more layers of wood together to make a thicker, stronger piece of wood.
LAYUP - The application of epoxy to fiberglass cloth on wood.
LINES PLAN - A drawing of a kayak showing the curves of the hull as represented by waterlines, buttocks, diagonals, and profile views of the kayak.
LOFTING - In making kayaks, it is the process used to produce station molds from a table of offsets. The intersections of the contours of various horizontal and vertical sections are measured from an imaginary base line. These station molds will attach to the strong back.
OFFSETS - A table of numbers describing the shape of a kayak.
OVERHANG - The section of the bow or stern that extends beyond the end of the waterline.
PLAN VIEW PROFILE - A drawing of the kayak from the top down.
PLUMB - Exactly vertical.
PROFILE - Looking at the kayak from the side.
RESIN - The substance that is mixed with hardener to make epoxy.
SANDWICH CORE - A laminate constructed of an inner core of wood (usually cedar in kayaks) with fibreglass mixed with epoxy on the outsides.
SHEER - The top wood strip on the hull of the kayak. The deck meets the hull at this point.
SKIN - The surface of a kayak made up of a wood-glass-epoxy laminate.
STATION - (Also called sections or forms) One of a series of equally spaced transverse "slices" of the hull, as shown in the line drawing of the offset tables. Stations once drawn and cut out are placed on the strong back at predetermined points.
STRIP PLANKING - A planking method that uses strips of wood installed longitudinally and edge-glued together. Planks most often are made with "bead" and "cove" edges.
STRONG BACK - A stiff, solid support used to attach stations to when building a kayak. The strong back keeps all the stations in line and solid.
WET OUT - To apply epoxy to fiberglass cloth.
