20080308030 | Portable boat having a plurality of attachable segments - A portable boat having multiple sections, which are connected together during use and are stacked together when not in use is disclosed. Each boat section is made of aluminum and attached in such a manner as to preserve the buoyancy and integrity of the boat. The boat is formed of a bow section, stern section and at least one center section. The boat sections are constructed with male and female slip coupling mechanisms and seat mechanisms such that when connected, the boat is rigid and of uniform width. Each point of attachment is characterized by two separate connecting mechanisms. This provides for a rigid and secure attachment between boat sections. Moreover, in the case of failure of one of the connecting mechanisms, it maintains the connection between the boat sections. | 12-18-2008 |
20100024709 | TAKE APART WATER CRAFT - A water craft comprises two or more sections with mating bulkheads and a tensioning device extending from bow to stem and passing through said bulkheads such that the tensioning device holds the sections together for use on the water. The mating bulkheads have inwardly and outwardly tapering ridges which guide the bulkheads into locking engagement as the tensioning device draws the sections together. The tensioning device is a strap which is attached internally to the bow and stem of the craft and is tensioned by a ratchet. | 02-04-2010 |
20100050922 | Portable collapsible boat - The invention is a portable collapsible boat comprising one or more rigid cockpit sections, constructed of a material such as fiberglass, attached to a bow section and a stem section, which are constructed of fabric material covering a skeleton of longitudinal stringers and ring frames, and are attached to the rigid cockpit section(s) by means of a belt, buckles, and/or flanges. The hybrid folding boat combines the best features of rigid boats, such as performance and durability, with the best features of existing folding boats, such as transportability, without suffering from the drawbacks of rigid boats (mainly the extensive storage space required) or folding boats (mainly weight). The hybrid folding boat is lighter, easier to transport, more rugged, safer, easier to assemble, and stiffer than previous folding boats, adapts easily to a sailing rig, and facilitates one or more passengers. Manufacture of the boat is simpler than that of conventional folding kayaks because it has fewer parts and less dependence on precision stitching of the fabric covering. | 03-04-2010 |
20100058970 | Sectional boat - A sectional boat includes fore and aft boat sections releasably couplable together by a releasable coupler cooperating between the fore and aft boat sections, wherein the releasable coupler comprises at least one dovetail coupler.

Each tenon is sized to snugly slidably mate into a corresponding female dovetail groove in the first boat section. Each tenon includes a substantially vertically upstanding lug mounted to and extending upwardly from an upper most end of each tenon so as to extend above an upper edge of the first boat section when each tenon is snugly mated in the corresponding female dovetail groove. Each lug includes an aperture. The coupler further includes a latch member for latching in each aperture so as to releasably lock each tenon in snug mating engagement in the corresponding female dovetail groove. | 03-11-2010 |
20100058971 | Portable boat in nesting sections, with waterproof fabric cover incorporating a stabilizing keel - The present invention introduces a small boat (kayak or hybrid kayak-canoe) made in a plurality of nesting sections.

20110146561 | Sectional boat - A sectional boat includes fore and aft boat sections releasably couplable together by a releasable coupler cooperating between the fore and aft boat section transoms. When the boat sections are assembled to form the boat, the fore and aft boat section transoms abut in opposed facing relation to one another. The releasable coupler may include at least one dovetail coupler having at least one female dovetail groove in each of the transoms and disposed so as to be aligned and opposed facing when the transoms are in their opposed facing relation. Each dovetail coupler may include at least one pair of male dovetail tenons mounted thereon in oppositely disposed relation so to engage in their corresponding opposed facing female dovetail grooves. Each tenon is sized to snugly slidably mate into a corresponding female dovetail groove in each of the transoms. Each tenon includes an upstanding lug having an aperture. A rigid member mates through the aperture so as to releasably lock each tenon in its corresponding female dovetail groove. | 06-23-2011 |
