Describes how the capture of illegal shrimp-poachers becomes a problem of triangular geometry and relative speeds of chase. In particular, the pirates, trapped on a ship, the chasing posse and the point on the shore where escape can take place form an equilateral triangle and the posse's sail boat goes twice as fast as the row-boats of the pirates, thus bifurcating the chase route into two zones: a. the segment over which the pirates can move without the posse having to react and yet keeping their escape impossible and b) the segment, which once reached by the poachers, guarantees their escape. The story is part of the book, “Tales of the Fish Patrol” and available for download here.
