Buoy for measuring wave slopes.

摘要

Buoy provided with a mainly circular disc shaped body (1) having a mainly horizontal lower surface (4) and protruding downwardly from said lower surface a central circular protrusion (3) having a smaller diameter than said lower surface and suchlike dimensioned that with a horizontal current the pressure deviation caused by said protrusion generates by its working on said lower surface a tilting moment opposite and at least equal to the tilting moment caused by the protrusion itself.
