Sail term: The fore and aft curvature of a sail in relation to its chord. Should not be fiberglassed. This term Boat Construction Terminology 403 is primarily used in conjunction with propellers and rudders. When cavitating, the propeller will speed up, Boat Construction Terminology 403 but power is lost; the rudder may lose steering action.

Cavitation most often occurs when turning. Both Boat Construction Terminology 403 result from a loss of a constant solid water flow. Power catamarans usually require deflectors when Boat Construction Terminology 403 Boat Construction Terminology 403 a single motor is used, to direct a flow of water to the propeller.

When there is more than one sail, CE's will be given on the drawing for each sail plus a combined CE. On a triangle, the CE is the point at which the lines bisecting each angle cross. The location of the CE fore and aft, affects the way the boat turns into the wind. Checks result from tension stresses during the drying process.

CLEW The lower, aft corner of a fore-and-aft sail, where Boat Construction Terminology 403 the leech meets the foot. Also called a schooner bow. Webster's New World Dictionary.

Fiddles are frequently left open at the corners for drainage. FILL The thread that Boat Construction Terminology 403 runs across sail cloth from edge to edge.

The term is most often used in reference to Stitch-N-Glue boat building. A fillet is made with activated epoxy resin, thickened with various fillers, to a putty consistency. The putty is "globbed" into place and smoothed with a rounded tool.

This is a shipping term, not a boat term. FOOT The lowest edge of a sail. This is an naval architecture term. It will usually be seen on the 2 plansheet, where the various stations are shown. This represents the end of the stem, or the last station from the transom.Boat Construction Terminology 403

A sail that fills that area. Frames can be divided into two categories: sawn or bent frames. Sawn frames are assembled from separate pieces, either lapped or gusseted together to form the station contour.

Bent frames are bent around a form or into a hull using one or more layers of solid wood. No Glen-L designs use bent frames. Frames can be lapped with a piece Boat Construction Terminology 403 of plywood filling the interior frame space to form a bulkhead.

Also called garboard strake. Garboard drain plugs are installed in the at the lowest point along the garboard. GEL COAT A semi-thixotropic, Boat Construction Terminology 403 air-inhibited, usually pigmented resin that is applied to a waxed mold surface over which subsequent fiberglass layup is made.
