Most Hunter sailboats have cast iron keels. Because of the difficulty in grinding down cast iron, fairing one of these keels involves staightening out the profile and leading edge without adding excessive amounts of fairing material. The Universal™ Template kit works very well for this. Other boat owners have used the following Universal™ Template kit chordlengths. Owners' wishing to simply check the keel should only purchase the shortest and the longest chordlengths. Owners desiring more templates should specify additional chordlengths between the sizes listed in the table. There aren't a "correct number" of templates required for fairing the keel, but rather with what the person fairing feels comfortable. Most people like a template for each 10" to 20" of keel height. For available chordlengths, pricing and an Universal Template™ Kit Order Form follow this link.

If your boat has a lead keel and you would like a quotation for a Compukeel™ Template kit or assembled templates, please send, or e-mail the keel offset dimensions. These usually are available from the designer or manufacturer. If your boat has a cast iron keel, or the keel-offset data isn't available, you will want to use the Universal™ Template Kit.

If you would like assistance in selecting patterns for the Universal™ Template Kit, measure the keel chordlength at the top and bottom of the ballast, and the vertical distance between these chordlengths. Knowing the vertical distance between these two measurements will help determine the number of templates. To measure the chordlength, hook the end of a tape measure on the trailing edge of the keel. Pull the tape measure forward to the point of maximum keel thickness. From the point of maximum thickness forward, the tape measure should pulled forward parallel to the centerline of the boat. Sight across the tape measure to determine the location of the leading edge of the keel. Send us these dimensions in our Universal™ Template Kit patterns to use request form for a a recommendation on which patterns to use if you are having trouble deciding.
