Scoop point buoy
A buoy that is adapted to resist entanglement with a trawler net that may be dragged over the anchor and buoy. The buoy may have an indentation on the body of the buoy that causes the buoy to pivot as a trawler net pulls the tether down and slides across the buoy. A lead-in ramp surface increases in thickness from the lower end to a transition area spaced from the lower end. A reorienting ramp surface extends from the transition area to the side of the housing that tips the buoy to a generally horizontal orientation as the object traverses the reorienting ramp surface.
1. A buoy that is resistant to entanglement with a trawler net comprising:
an anchor;
a tether secured to the anchor on a first end of the tether;
a buoy having a lower end that is secured to the tether on a second end of the tether, the buoy has a first side that defines an indentation that is proximate the second end of the tether, the indentation has a lead-in ramp surface at the lower end to facilitate the trawler net passing over the lower end and that increases in thickness from the lower end to a transition area spaced from the lower end, and a reorienting ramp surface that extends from the transition area to an upper end of the first side of the buoy that tips the buoy to a generally horizontal orientation as the trawler net traverses the reorienting ramp surface.
2. The buoy of claim 1 wherein the lower end of the buoy has a lower surface that lies in a plane that is angularly oriented relative to a longitudinal axis of the buoy, and wherein the tether is secured to the buoy between the lead-in ramp surface and the lower surface.
3. The buoy of claim 2 wherein the lower surface and the lead-in ramp surface define an arcuate leading edge.
4. The buoy of claim 1 wherein the tether is attached to the lead-in ramp surface at the lower end at the outer periphery of the buoy.
5. The buoy of claim 1 wherein the transition area is a concave arcuate surface disposed between the lead-in ramp surface and the reorienting ramp surface.
6. A buoy system comprising:
a base having a top side and a wall extending about the base;
a tether attached on a lower end to the base;
a buoy is attached to an upper end of the tether at a spaced location relative to the base; and
a buoy having a lower end that is secured to the tether on an upper end of the tether, the buoy including a housing, a sensing system that is at least partially enclosed within the housing, wherein a first side of the housing defines an indentation that is proximate the upper end of the tether, the indentation has a lead-in ramp surface at the lower end to facilitate the object passing over the lower end, the lead-in ramp surface increases in thickness from the lower end to a transition area spaced from the lower end, and a reorienting ramp surface that extends from the transition area to an upper end of the first side of the housing that tips the buoy to a generally horizontal orientation as the object traverses the reorienting ramp surface.
7. The buoy system of claim 6 wherein the lower end of the buoy has a lower surface that lies in a plane that is angularly oriented relative to a longitudinal axis of the buoy, and wherein the tether is secured to the buoy between the ramp surface and the lower surface.
8. The buoy system of claim 6 wherein the transition is provided on the buoy between the lower end of the buoy and a center of buoyancy point on the buoy.
