Hull

Examination of the starboard hull was limited to a 40 foot section of frame tops from 60 to 100 feet aft. Frames in the midships area are generally doubled. Triple frames and one set of quadruple frames, located at 83 feet on the baseline, are found in the engineering space. This heavy construction appears limited to the engineering space to support heavy machinery.

Futtocks are molded 5 1/2 inches with a sided dimension ranging between 4 and 8 inches. The average sided dimension is 6 inches. Room and space dimension varied depending on double or triple framing elements. Space averaged 11 inches while room measured 13 inches for double frames and 16 to 19 inches for triple frames. Fasteners used to hold the futtocks together were not observed.

Outer hull planking measured 2 to 2 1/2 inches thick but width and fastenings were not recorded. Ceiling planking on the interior is 2 1/2 inches molded and butts against the lower edge of the deck clamp. The deck clamp is 5 inches molded and 27 inches sided. It is made of two timbers butted along the edge measuring 12 and 15 inches wide respectively.

The clamp supported deck beams extending from the side of the hull to form the structure of the paddle guards. The beams pass through a 1 inch notch on top of the sheer strake, to the outer edge of the guard (Figure 7). They are sided 5 1/2 inches, molded 7 inches and placed on 24 inch centers. Each deck beam has broken at the side of the hull causing the guard to sag. In addition to the clamp, hanging and dagger knees provided extra support for the deck beams.

Two articulated hanging knees are located in the engineering space, just forward of the boiler face. The tops measured 4 inches wide and 14 inches long. The vertical side was not measured.

Two dagger knees are located between 60 and 65 feet on the baseline (Figure 7). In design, the knee angles forward with the top beveled to fit flush against the aft side of the deck beam. The lower end of the knee slants diagonally aft, approximately 30 degrees below the vertical plane, to pass under the adjacent deck beam on the aft side. It is fastened to the deck clamp. The knees are placed on alternate deck beams. A disarticulated dagger knee was brought to the surface for documentation. It is 4 1/2 inches wide, 27 inches long on the beveled edge and 41 1/2 inches long on the lower portion. Square headed iron bolts, 1 inch in diameter, were used to fasten the knee to the ship; two on the deck beam and three on the clamp.

The aft cargo hold excavation exposed a similar knee, 139.5 feet aft of the stem on the port side. This knee angled aft, the opposite direction of the dagger knees in front of the paddle shaft.

This form of kneeing provides longitudinal support against hogging forces. It was one of several proposed methods used in England during the late-18th and early-19th-centuries to combat hogging problems as ship length increased. British Admiralty plans of the American frigate President, captured in the War of 1812, illustrates extensive dagger kneeing (Figure 8). This is a rare American example of the technique. With the exception of a few warships, dagger kneeing was not used in the United States (Chapelle 1967:206-207). As a British colony, Canada had much closer political, economic and social ties with Britain during the 19th-century which may account for this trait on the Maple Leaf.
