ABSTRACT:
A wave-quelling float for marking lines extending across the surface of a body of water is provided, comprising a supporting body of lightweight plastic material; a hub in the body with a central passage therethrough for reception of a float-tethering marking line; a plurality of buoyant members arranged radially about the hub, and preferably disposed at regular intervals about the hub to float the body in a manner such that at least one-half the body is above the water with the float balanced for free rotation in the water about a float-tethering line; the body having a web portion extending radially from the hub, and a plurality of wave-quelling vanes extending laterally from the web on at least one side thereof; the vanes being spaced and shaped to receive surface surges and waves on the body of water, absorb the impact thereof as rotation of the float, and thereby quell them. The body of the float is preferably made in one piece of plastic, with pieces of buoyant material inserted in the float supports, and attached thereto.
