FAIRING: A line is drawn from the frame closest to the stem, or the next aft frame, to the center of the chine at the stem. The portion above this line must faired to provide a flat surface for the bottom planking to mate to. The side planking will be fastened to the portion below this line. In most instances, the chine will follow the angle of the side frames so that fairing the chine for the side planking is unnecessary. FAIRING: Any minor discrepencies must be faired out of the frames. In planing boats, it is imperative that the longitudinal lines in the aft section be straight lines. Use a straight edge to determine fairness. Curved lines on a planing boat can cause "porpoising", or to ride bow down. Although this effect does not occur on displacement boats, lines should be fair for esthetic reasons and unfair lines will have some effect on performance. NEXT |
