Patent number: 5697736Abstract: Systems for reinforcing various waterfront properties such as riverbanks, lake shores and beaches of oceans, bays and the like to protect them from erosion and encourage accretion of beach sand and gravel are disclosed. Improved seawalls and the like can be built from L-shaped members having a vertical wall portion, a horizontal footer, a vertical key protruding below the footer and an angular splash plate protruding from the wall opposite the footer. Systems based upon such seawalls may further comprise groins perpendicular thereto which are built from inverted "T"-shaped members, and optionally rows of such inverted "T" members parallel to the seawall as well. Further, erosion of the bank above the seawall and/or the beach below same may be reduced by partially covering them with water-permeable concrete mats. One or more groins extending perpendicular from the seawall may preferably be fabricated of inverted "Double T" members and adapted to support a pier.Type: GrantFiled: August 3, 1994Date of Patent: December 16, 1997Assignee: Custom Precast Concrete, L.L.C.Inventors: Sidney E.

Patent number: 5505153Abstract: Twin-hulled boats such as SWATH (Small Waterplane Area Twin Hull) boats are designed and built to be so dimensioned as to fit transportably and removably atop the sidewalls of the open bodies or beds of various vehicles such as pickup trucks, trailers and the like. The horizontal deck and substantially solid hulls or struts of the boat provide a cover, closure or "cap" for the truck bed while installed. Such boats can be easily removed from the truck bed for use or storage. In one embodiment, the twin hulls have a cross section which is a hybrid of the relatively wide, shallow hulls of a catamaran and the narrow, deep struts attached to the lower flotation hulls of a SWATH boat. In the SWATH embodiment, the flotation hulls can be removed for separate transport, the struts themselves being secured atop the sidewalls, or the hulls can be left installed and themselves secured to said sidewalls.Type: GrantFiled: April 7, 1994Date of Patent: April 9, 1996Assignees: S.
