A knock-down boat assembly comprises bow, mid and stern water-tight transverse hull sections, each having fore and aft ends, concave side walls and a transverse bulkhead at the aft end of the bow section, at the fore and aft ends of the mid section and at the fore end of the stern section.

A knock-down boat assembly comprises bow, mid and stern water-tight transverse hull sections, each having fore and aft ends, concave side walls and a transverse bulkhead at the aft end of the bow section, at the fore and aft ends of the mid section and at the fore end of the stern section. The stern section is nestable in the mid-section and the bow section is nestable in the stern section when in the knock-down configuration. The forward bulkhead of the stern section is secured in a position butting against the aft bulkhead of the mid-section and the aft bulkhead of the bow section is secured in a position butting against the fore bulkhead of the mid-section when the boat is assembled for sailing. The side walls of the mid-section each have a short length extending from the aft bulkhead thereof which extends obliquely outwardly from the plane of the longitudinal curvature of the stern section such that the width of the aft end of the mid-section increases rapidly to a greater width than the fore end of the stern section whereby the stern section is nestable within the mid-section with the forward bulkhead located more closely adjacent the aft bulkhead than would be possible with a smooth longitudinal arc of curvature.

A knock-down boat assembly comprising, bow, mid and stern water-tight hull sections, each having, fore and aft ends, concave side walls and a flat transverse bulkhead at the after end of the bow section, at the fore and aft ends of the mid section and at the fore end of the stern section, the concave side walls of the stern section converge continuously from it fore end bulkhead to its aft end bulkhead, the stern section being nestable in the mid-section and the bow section being nestable in the stern section when in the knock-down configuration, the side walls of the stern section converge continuously from the fore end bulkhead to the aft end bulkhead such that the width of the stern section is a maximum at the fore end, the forward bulkhead of the stern section being secured in a position butting against the aft bulkhead of the mid-section and the aft bulkhead of the bow section being secured in a position butting against the fore bulkhead of the mid-section when the boat is assembled for sailing, the side walls of the mid-section each having a short length extending from the aft bulkhead thereof which extends obliquely outwardly from the plane of the longitudinal curvature of the stern section such that the width of the aft end of the mid-section increases rapidly to a greater width than the maximum width of the stern section whereby the stern section is nestable within the mid-section with the forward bulkhead located more closely adjacent the after bulkhead than would be possible with a smooth longitudinal arc of curvature.
