ABSTRACT:
The invention relates to a freeboard measuring device which comprises an elongated housing having a rectangular cross-section form, a central part of the device body. A pair of fins fixedly connected to the housing on each of its sides extend substantially the length of the hosuing and have at least slightly greater lateral dimensions than the lateral dimension of the housing. The fins are triangular in cross section, with the tops of the triangles facing outwardly and providing the device with streamlined characteristics. The base of the triangles does not exceed in length the depth of the housing. The central portion has a main chamber for housing a gauging stick. The main chamber is divided into a lower and upper secondary chamber with the lower chamber having water ingress and separated from the upper chamber by a separation wall with openings to allow water to enter the upper chamber. The lower chamber has a packing of fibrous material to prevent water turbulence. The gauging stick has a strip of water-sensitive material fixedly attached thereto, the water sensitive material retaining, at least temporarily, a water mark. The bottom of the stick is concave or jagged so as not to impede the water flow. The open top of the main chamber is closed by a plug affixed to the top of the dipstick to prevent rain from entering the upper chamber and obstructing measurements. A stablizing transverse bar provided by a second embodiment of the invention prevents rotation of the device in strong currents.
