The kayak-form canoes of the upper Yukon Valley and those used in northern British Columbia and in Yukon Territory had ends with a long rake that came up in a straight line from an angular break at the bottom line to the height of the sheer amidships or thereabouts; there a gradual upward curve continued to the stem-head. The stern was 2 inches or so higher than the bow, and the rake of the latter was usually about an equal distance longer than that of the stern. The sheer was nearly straight, with only about 2 inches of sag from the heel of the stem to that of the stern. Beyond the heels, the sheer lifted in a fair sweep, becoming sharper toward the ends, where the broadened inwales were secured on top of the stem and stern pieces. There was no rocker in the bottom, and some examples showed as much as ⅜ inch of hog amidships. The bottom was flat athwartships and the almost straight sides flared a good deal. The turn of the bilge was on a very small radius and in some canoes appeared angular. The bow deck was usually just under one-fifth the length of the canoe. Most of the canoes did not have a stern deck, at least on the Yukon headwaters, but on those that did, it was about one-ninth the length of the canoe. The greatest beam was abaft amidships and the canoe was usually about 1½ inches deeper at the heel of the sternpost than at the heel of the stem. In plan, the ends (at gunwale and bottom frame) were convex; the gunwale ends alone might appear slightly hollow close to the posts in some examples. The canoes in Alaska and British Columbia and at the headwaters of the Yukon had a rigid bottom structure, with the splint spreaders usually numbering five. The 1-man hunting canoes were commonly 18 to 19 feet long, 24 to 27 inches beam, and usually 10 to 11 inches deep amidships. The single example of a family or cargo kayak-form that has been measured from this area was 20 feet 1 inch overall and 30¼ inches beam over the gunwales. It was 18 inches wide on the bottom frame, 13 inches deep amidships, 14 inches deep at heel of stem, and 16 inches at heel of stem-post. Height of the stem was 29 inches, of the stern 30½ inches, the after rake was 38 inches, and the fore rake 40½ inches. The canoe had no decks and was rather sharp-ended.
