Abstract: A watercraft loading and launching apparatus for a pickup truck having a trailer hitch receiver. The apparatus has an elongated receiver bar with one end adapted to fit a trailer hitch receiver and a cross member support bar secured to the other end. The cross member support bar may be straight or angled for supporting watercraft having a V-bottom, a semi-V bottom, a flat bottom, or equipped with pontoons. There is disclosed a second embodiment wherein the cross member support bar has hinged extensions for allowing use with both V-bottomed and flat-bottomed watercraft. The apparatus may also include a cradle assembly for supporting the watercraft within the cargo bed of the pickup truck.

Abstract: Water quality sensor apparatus comprising a substrate on which a plurality of sensors are supported in spaced apart relationship, each sensor being responsive to a different water characteristic and each sensor comprising a sensor region which, in use, is arranged to be contiguous with water the characteristics of which are to be sensed, which sensor regions are electrically connected to connector means via conductors supported on the substrate, the conductors and the connector means being arranged to be non-contiguous with the water in use of the apparatus.
