Abstract: A T-bar lockable linkage between the gunnels and forward of a marine craft limits opening of side and central storage containers. The linkage includes a pair of tubular outer arms independently pivotally connected to a center link having an extended position for connection to the mounting brackets and a shortened position for removal therefrom. A shiftable lock block slidably supported on the linkage effects rigidized coaxial alignment of the outer arms in the extended position, The lock block includes a locking hub for releasable connection with a transverse center arm for limiting opening of the storage containers. The hub carries a keyed locking device including a latch bolt that engages the cross arm assembly to unitize the assembly and prevent separation of the components.

Abstract: A T-bar lockable linkage is deployed between the gunnels and forward seating or casting area of a marine craft and effective to limit opening of an array of side and central storage containers including a telescoping cross bar assembly that is connected to mounting brackets at the sides of the front boat deck. The mounting brackets include universal connectors that allow self alignment of the cross bar assembly, notwithstanding varying boat configurations or installation inaccuracies. The cross bar assembly includes a slotted slidable hub that may be aligned with a forward anchorage location, preferably an existing pedestal base for a swivel boat seat. The cross bar assembly includes matching holes aligned with a medial slot in the hub. A front anchor is releasably attached to the front pedestal base and slidably receives a center locking bar. With the center locking bar in place, the front anchor is conditioned against removal.
