ABSTRACT:
The miniboats introduced in my U.S. Pat. 4,090,270 were basically novel in configuration, method of construction, ease of boarding by a swimmer, flotation effectiveness relative to lightness and compactness when stowed, degree of hypothermia protection achieved, and security in wind and water far beyond the capabilities of comparable pneumatic craft of traditional design; but they were not well adapted for entry by persons desiring to board them without a wetting. The vessels disclosed herein have overcome that problem. They have structurally integrated decks with dry-access openings that provide twice the retained buoyancy, a barrier to wave influx over the gunwales, an inherent self-righting capability, unprecedented storm security, ride stability, and magnified hypothermia protection. Some have integral leg articulation and propulsion and/or vessel-integrated suspension system for retarding descent to water from high elevations, auxiliary propulsion provisions, etc. Models sharing design characteristics of these life-support craft are highly adapted for expansion of seasonal, latitude, and ambulatory opportunity for scientific work and for recreation. Their diminutive weight and bulk enable transport to shores and banks that become inaccessible when carrying watercraft of greater weight and bulk and lesser portageability, seaworthiness, and wide-spectrum protective capability.
