Abstract
A freeboard-measuring device has a central housing with streamlined fins extending along sides and bottom of the housing to prevent uplifting of the housing when lowered into water and minimize resistance to wind and current. The housing defines a chamber with a bottom water ingress allowing swift filling of the inner chamber. A calibrated gauging stick is removably a positioned within the inner chamber. A stabilizing cross bar and a transverse bar are secured by flexible connectors above the housing. The attachment of the stabilizing bars above the water-contacting portion of the measuring device allows to avoid water resistance when using the measuring device.
Claims34
A freeboard measuring device, comprising:
- an elongated housing means having a means for water ingress formed in said housing means;
- a means for freeboard measurement mounted, at least in part, within said elongated housing means;
- and
- a stabilizing means secured above the housing means and extending transversely to a longitudinal axis of the housing means for stabilizing vertical orientation of said housing means.
A freeboard measuring device, comprising:
- an elongated housing having means for water ingress formed in a bottom thereof and a central chamber in fluid communication with said means for water ingress;
- a means for freeboard measurement detachably mounted, at least in part, within said housing;
- and
- a stabilizing means secured above the housing means and extending transversely to a longitudinal axis of the housing means for stabilizing vertical orientation of said housing and facilitating resistance to wind and wave action, said stabilizing means comprising a cross bar secured above said housing and a transverse bar secured above said cross bar.
A freeboard measuring device, comprising:
- an elongated housing having means for water ingress formed in a bottom thereof and a central chamber in fluid communication with said means for water ingress;
- a pair of streamlined fins securely attached to and extending along elongated sides and bottom of the housing;
- a means for freeboard measurement detachably mounted, at least in part, within said housing, said means for freeboard measurement comprising a calibrated gauging stick having a strip of porous moisture-sensitive material attached thereto, said strip retaining, at least temporarily, a water mark upon contact with water;
- and
- a stabilizing means secured above the housing and extending transversely to a longitudinal axis of the housing for stabilizing vertical orientation of said housing and facilitating resistance to wind and wave action, said stabilizing means comprising a cross bar secured above said housing and a transverse bar secured above said cross bar by a swivel member to allow adjustment of the position of said cross bar in relation to the transverse bar.
