Abstract: The improved revetment system is created using a plurality of substantially identical blocks which comprise a body having at least one channel therein leading to a slot and at least one arm extending outwardly of the body and terminating in a locking ear. The ear engages in a slot of an adjacent block and is of less depth than the slot, with the arm being of a length at least equal to and preferably greater than that of the channel, the slot including a removable spacer tab therein which abuts a terminal edge of the ear to keep the blocks spaced apart and an area of the block defined by the arm and ear having an arcuately downwardly sloped top surface with a terminal edge of the ear defining a lowermost position along the arcuate surface.

Abstract: The erosion control blanket of blocks comprises a plurality of concrete blocks having a preselected configuration and being joined to adjacent blocks of the configuration by at least one of a plurality of embodiments of a reinforcing lattice structure. Individual blankets may be joined together to create a desired configuration for a substrate covering. Provision of the blocks in a blanket configuration provides a process of laying the blocks with attached lattice which is time and labor saving.

Abstract: An interlocking grid matrix system is adapted for placement over terrain for use as a revetment. The grid matrix system includes a plurality of substantially identical revetment blocks which are interconnected to allow for omnidirectional movements relative to each other. Each revetment block includes a precast grid body having a first major surface, a second major surface, and an edge extending between the major surfaces to define a periphery for the grid body. The grid body further includes a plurality of spaced ears which are joined to and extend from the edge and a plurality of locking channels disposed inwardly of the edge between the ears. Each channel opens to each major surface and the edge and is specifically configured to releasably interlock with an ear of an adjacent grid body such that movement in any direction is permitted between adjacent revetment blocks while maintaining an interlocking relationship therebetween.

Abstract: A fishing rod holder capable of placement in the ground or attachment to a boat comprising hollow, interconnected upper and lower members positioned at acute angles to each other and preferably having a bracket for attachment to a boat hull.
