As a Navigator NAUTICAL LOG was always fascinated by bird migrations and how they found their way coming to the conclusion, several decades ago, that it was by following the Earth's magnetic field.  Of course it is not quite that simple as one size does not fit all there are several types of bird movement some quite short.  However some migrate from Northern Canada to Southern South America - now there's a thought wonder if such birds tweet in french, English and Spanish.  Seriously living here in South Florida we are on a major migration route and this is evident this month as the NAUTICAL LOG patio bird feeders are extremely busy.  Florida lies between an Agonic Line and Isogonic Line 10° so it seem to make sense that the long distance migratory birds do make use of the Earth's magnetic field.  The short distance migratory birds likely use the Sun as a compass as most fly by day and rest at night.  However Warblers are night fliers so they reinforce for NAUTICAL LOG the magnetic field navigation system theory.

Just this weekend there was an interesting article in the local paper about all this and coupled with observations of the patio bird feeder got the brain cells working.  In the State of Florida it is possible to observe some 485 species and of those just this last couple of weeks we have seen:
  • Northern Cardinal
  • Blue Jay
  • Spot-breasted Oriole
  • Painted Bunting
  • Red-bellied Woodpecker
  • Savannah Sparrow
  • House Sparrow
  • Palm Warbler
  • Boat-tailed Grackle

While we enjoy these birds let us not forget that 400 of our fellow seafarers are held captive by pirates both ashore and off the coast of Somalia.

It sometimes happens that one is going to write a Post on a subject when lo and behold there is already an excellent one.  Such is the case today; so rather than repeat everything let me refer you to the source of that Post

At present we are experiencing Perigean Spring Tides which occur when the Moon is at perigee on its oval path that is the closest point to Earth.  One of the principal results are higher than usual Spring Tides as against the Neap Tides.

Should you be interested in the full explanation of this phenomenon then you might like to reference "Old Salt Blog" which has an excellent explanation of this event and uses all the correct terms - quite unlike our Media here in South Florida.

Good Watch.


In addition to the recent "Standing Down" of training voyages for its Midshipersons the United States Merchant Marine Academy (USMMA) has received warnings about the quality, or lack thereof, of its training programme.  The Middle States Commission of Higher Education (MSCHE) report stated that accreditation was in jeopardy for non-compliance in certain areas.

Coupled with the continuing problems requiring disciplinary actions including dismissal from the Navy the United States Navy (USN) has had in recent years this does not bode well for the professionalism of the seafaring community of the United States.

It is clear to this writer, an International Master Mariner with 50 years of experience, that the training sources for both Officers and Ratings need an immediate complete examination and review.  Currently the Officer commanding riverine craft based in Bahrain has been dismissed.  Another nine Officers and Ratings are under disciplinary action as a result of the capture by…


NAUTICAL LOG has on previous occasions discussed the SS El Faro VDR in a Post titled RELUCTANCE TO RECOVER and two other Posts about the VDR (Voyage Data Recorder) of the SS El Faro

The Ship sank in Hurricane Joaquin on October 01, 2015 off the Bahamas.  There has seemed to be a reluctance by all parties involved to continue the attempt to recover the VDR from some 15,000 feet - admittedly a considerable depth.  However because of the importance of possible data on the recorder such an attempt must be made.

Finally the NTSB has contracted with the USN Supervisor of Salvage to assist in the recovery of the VDR.  The USNS Apache will depart in early July 2016 together with USCG, Phoenix International and an underwater operating vehicle the CURV-21.

Once the VDR is recovered it will be brought ashore to the NTSB laboratory and thoroughly studied to download and analyze the information.  With these results in hand the USCG will conduct a two hearings to investigate the sinking and questio…
