Templates would be required. It is normal for the forward and after portions of radius to be easier to plate than the midships portion. The chine tends to be straighter towards the ends of the hull, allowing fairly long sections of radiused plate to be used. In the middle, the chine normally has a large amount of curvature on plan and in elevation. This gives a tighter compound curve which the radiused plating will not successfully cover unless it is cut into short lengths.
Some builders prefer to split the radius lengthwise in the midships area of the hull.
This can allow slightly longer lengths of radiused plate to be used. In addition to the savings on plating, there is normally a saving on stringers as well. A multi-chine form forces most stringers to run full length and does not allow efficient selection of stringer spacing. The stringers must fit between the chines. With radiused chine construction, stringer spacing can be varied throughout the length of the hull to suit load requirements, although it is normal for them to run parallel to the sheer.
