초록 ▼

An inflatable boat for high speed towing applications having a compartmentalized hull and an improved tow-ring mounted beneath the hull, the hull including first and second buoyancy chambers, the second chamber being vertically disposed beneath the first chamber. Inclined, flexible reinforcing partitions are substantially vertically disposed within the second buoyancy chamber to substantially divide the chamber into a plurality of sub-chambers, and restrain the bottom wall of the chamber upon inflation, to form outwardly projecting convex arcuate portions having longitudinal grooves defined therebetween. The tow-ring includes a reinforced hollow structure having interior reinforcing walls and a convexly curved top wall, portions of the walls together defining a peripherally disposed pair of longitudinal tie-line tunnels and a transverse tie-line tunnel, sized to receive a tie-line therethrough.

An inflatable frame-less boat comprising: a first buoyancy chamber; a second buoyancy chamber disposed beneath said first buoyancy chamber, wherein said second buoyancy chamber includes a top wall portion, a bottom wall portion and a central longitudinal axis; and flexible partition means disposed within said second buoyancy chamber, wherein said partition means includes a pair of flexible reinforcing partitions, substantially vertically disposed within said second buoyancy chamber, said pair of flexible reinforcing partitions including first and second longitudinal edges, said first edge being joined to said top wall portion, said second edge being joined to said bottom wall portion to form a bottom edge seam laterally inward towards said central longitudinal axis to define a generally V-shaped configuration in vertical cross-section, said flexible reinforcing partitions defining a central and lateral sub-chambers for providing horizontal rigidity to said second buoyancy chamber and reducing intra-buoyancy chamber air flow, said chambers sharing a substantially vertical dividing wall, and restrain the outward expansion of said bottom wall portion relative said top wall portion to create, upon inflation of said second buoyancy chamber, a second buoyancy chamber bottom surface contour having adjacent outwardly projecting convex arcuate portions defining longitudinal grooves between said adjacent arcuate portions. An inflatable boat tow-ring to distribute, over a surface area, towing forces applied thereto, said tow-ring comprising a member having first and second longitudinal tie-line tunnels and a transverse tie-line tunnel, wherein said member is a reinforced hollow structure including a base portion having a tapered periphery and a convexly curved wall extending inward and projecting outward from said base portion, portions of said convexly curved wall defining said first and second longitudinal tie-line tunnels and said transverse tie-line tunnel, said tunnels substantially peripherally disposed about said base portion for receiving said tie-line therethrough.
