Shape The Hasholme boat is made of one whole log and is generally log-shaped. It has a flat bottom outboard and also inboard. With the bottom horizontal, the top edge of the sheer line generally slopes down towards the bow. However, when the boat is afloat the sheer line becomes horizontal and the bottom gradually slopes upward. Near the bow, the bottom becomes even more rounded and distinctly angled. At the stern, the thickness of the bottom gradually increases to provide sufficient timber to support a transom. The forward upper edges on both sides of the hull are curved in sections and rebates to support extensions in the form of a washstrake. The overall length of the Hasholme logboat is , in maximum beam, and in maximum height. Bow The bow section of the Hasholme logboat has a most original design. It is made of two parts, lower and upper bow timbers, which together formed a front enclosure to the log. The lower bow piece is long and thick. On both sides of this timber there are symmetrical rebates which match similar rebates on the main hull as well as series of cleats with transverse holes through which the second and third transverse timbers passed. Those transverse timbers, three in total, not only fasten the lower bow timber to both sides of the hull, but also strengthened and linked the bow section. Forward of the groove for the foremost timber, there were three large vertical holes. The upper bow piece is also around 60 cm long and has a rather complex shape. The bottom section of the upper bow timber has a transverse lip to envelope the leading edge of the lower bow timber, and a series of longitudinal grooves on both sides to fit over the forward ends of the washstrakes of the upper part of the hull. This upper timber was fastened to the lower timber by three vertical tree-nails through corresponding holes in the lower bow. Those tree-nails were approximately long and 0.6 cm (¼ in) thick. Stern In general, the stern is at the right angle to the rest of the boat. Approximately forward of the stern, a transverse groove was cut into the bottom and sides to support the transom piece. Forward of the transom several grooves were cut to support transverse shelves, with the most aft shelf covering the transom. Such fitted transoms, which
