Ski Tow/Malahini construction
Fig. 4 - The transom is mounted on the building form so that the keel and bottom battens are straight lines in the aft section. It is imperative that these members not have humps or hooks as this can have undesirable affects on performance. These members should be checked periodically to insure that they remain straight.
Fig. 5 - The notches for the chines will be angled at each frame as needed to insure that the chine will mate firmly with the frame. Here Don is cutting the required bevel in Frame #4.
Fig. 6 - After the stem is beveled, the chine must have its outer surface extend to the center of the stem. Since the chine is installed before the stem is beveled, a "checking block" such as shown above, is used to determine its position. It may be neccessary to fair the chine blocking depending on the thickness of lumber used for the chines*.
*The chines will most often be 3/4" thick, but this can vary if the you surface plane the material from rough stock or have it milled.
