On Friday, April 13 2007 at 4:45 PM EST (0045z 2007/04/14), a MAYDAY call was made to the net frequency.   The S/V ARGONAUTA was in distress, actively being stalked by power vessel with 4 males on board.  The ARGONAUTA had made 4 course corrections, with the power vessel performing identical course changes shadowing the ARGONAUTA, and was now beginning to rapidly close the distance.  The ARGONAUTA was declaring a probable sea piracy situation in-process.

The S/V ARGONAUTA is a 43’ C&C sailboat, white with blue trim, with two females on board.

They reported their position as 18° 52.51’N x 67° 52.51’W (in the Mona Straits, Puerto Rico), steering a course of 111°T at 4.7 knots.

The pertinent information was obtained by the net and relayed to the USCG San Juan, Puerto Rico. 

The USCG scrambled a vessel and helicopter to the vessel in distress.  Due to propagation, USCG San Juan was unable to communicate to S/V ARGONAUTA on 14.300.  The MMSN acted as a relay station in support of the information exchange between USCG and S/V ARGONAUTA.

After arriving on-site, the USCG determined the vessel shadowing the S/V ARGONAUTA was a migrant vessel, and the vessel was detained.  The S/V ARGONAUTA continued on their voyage without further incident.

Involved controllers were AG4SI, K5MP and K5SIV
