Abstract: A boat hull cleaner comprises a pole having at least two parts 2, 3 which can be set at an angle with respect to one another, a float 6, and a brush 7, the float having a buoyancy portion which gives a minimum buoyancy to the float. The float has an opening or openings arranged to admit water into the float when it is tilted while under water with the result that effective buoyancy of the float is adjusted. The hull cleaner is formed such that when it is in use a human operator can hold one end of the pole from above water level and move it to manipulate the float and the brush beneath water level such that the float encourages the brush against a boat hull to assist the operator to clean the hull.

Abstract: A boat hull cleaner having a handle (not shown) and a knuckle (see FIG. 1), the knuckle 1 having a first portion 2 and a second portion 3, the first portion 2 having a first channel and the second portion 3 having a second channel, the first portion 2 having a first connector part 4 to be joined to a first tubular part of the handle, and the second portion 3 having a second connector part 5 joined to a second tubular part of the handle; the arrangement being such that a fluid can be caused to flow within the first tubular part of the handle, into the first and second channels of the knuckle 1, and then into the second tubular part of the handle, and wherein the first and second portions 2 and 3 of the knuckle 1 can be adjusted with respect to one another such that the first and second tubular parts of the handle assume an angle with respect to one another.

Abstract: A demolition shear is attachable to a mobile machine by one of two brackets. The brackets engage, alternatively, two of three pairs of mounting holes on the shear so the shear can be mounted at its proximal end to the stick or at its side to the boom of the machine.
