Abstract
Abstract A square-sterned dory of welded aluminum construction in which the chines diverge for their full length and an engine well is located forward of the transom and is open through the transom as well as through the bottom. Box cross-braces serve as seats and storage compartments, and bracing is added by a forward deck or seat and skirt providing a front compartment. A hawsepipe is provided at the bow which extends through the forward compartment to the forward end of the bottom for convenience in handling an anchor when the dory is used as a river drifter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
217 words
A dory comprising: a bottom panel having a stern edge, a bow end, and symmetrical side edges diverging aft for their full length from said bow end to the ends of said stern edge, said bottom panel having a flat stern portion extending from said stern edge forwardly approximately half the length of the dory and having a generally trapezoidal shape defined on three sides by said stern edge and rear portions of said diverging side edges, and said bottom panel having a curved forward position curving upwardly uniformly across its width from the fourth side of said stern portion forwardly between said side edges to said bow end, a transom sloping aft from a connection with said stern edge and having opposed upwardly diverging end edges, opposed outwardly sloping side panels connected to said end edges of the transom and side edges of the bottom and connected together at the bow to form a forwardly sloping stem, respective gunwales along the upper edges of said side panels, said gunwales diverging from said stem outwardly of and higher than said curved forward portion of the bottom panel, and then converging to the transom outwardly of and higher than said flat stern portion of the bottom panel, and combination cross-bracing and seat means extending between said side panels.
Claim 2
Dependent Claim
217 words
A dory comprising: a bottom panel having a stern edge, a bow end, and symmetrical side edges diverging aft for their full length from said bow end to the ends of said stern edge, said bottom panel having a flat stern portion extending from said stern edge forwardly approximately half the length of the dory and having a generally trapezoidal shape defined on three sides by said stern edge and rear portions of said diverging side edges, and said bottom panel having a curved forward position curving upwardly uniformly across its width from the fourth side of said stern portion forwardly between said side edges to said bow end, a transom sloping aft from a connection with said stern edge and having opposed upwardly diverging end edges, opposed outwardly sloping side panels connected to said end edges of the transom and side edges of the bottom and connected together at the bow to form a forwardly sloping stem, respective gunwales along the upper edges of said side panels, said gunwales diverging from said stem outwardly of and higher than said curved forward portion of the bottom panel, and then converging to the transom outwardly of and higher than said flat stern portion of the bottom panel, and combination cross-bracing and seat means extending between said side panels.
Claim 3
Dependent Claim
71 words
A dory according to claim 1 in which said combination means includes two box ribs which extend thwartships in spaced relation to said bottom between the side panels as side braces with one box rib being located about midway of the length of the flat stern portion of the bottom panel and the other box rib being located over the aft part of the curved forward portion of the bottom panel.
Claim 4
Dependent Claim
80 words
A dory according to claim 2 in which said bottom and transom have merging cutouts at the center line of the dory providing an open bottom and open rear for a well, side plates for the well extending between the rear box rib and the transom, and a cross-plate between said side plates at a location spaced aft of said rear box rib and defining the front of the well, said cross-plate being adapted to serve as an engine mount.
Claim 5

A dory according to claim 4 in which an open-ended hawsepipe extends from the bow end of said bottom panel to the intersection of said bow deck and skirt.
Claim 7
Dependent Claim
99 words
A dory according to claim 1 in which all of said panels and said transom are aluminum sheet and are welded together, continuous aluminum chines of angle section welded at the inside intersection of said side panels and bottom panels, a continuous aluminum center keelson welded to the bottom panel, a pair of continuous aluminum stringers spaced at opposite sides of the keelson and welded to the bottom panel, and aluminum cross-ribs extending between the keelson and the chines and partially cut out to overlap the stringers, said ribs being welded to the bottom panel, keelson, stringers and chines.
Claim 8
Dependent Claim
37 words
A dory according to claim 2 in which said box ribs comprises storage compartments spaced above said bottom panel and have an open top, and seats on the box ribs serving as covers for the open top.
