Winthrop was one of twenty sisters built at Bath Iron Works. They were given to the French government under the Marshal Plan to make up for losses to the fishing fleet in World War II. Winthrop is sister to Laita, cousin to Bad Bob's Big Boat.

I have been unable to determine which of the original sisters ended up as the Winthrop:

  • Charles Massot - 1948
  • Gris Brumaire - 1948
  • Jean-Pierre Robert - 1948
  • Lucien Marie - 1948
  • Lucien Gougy - 1948
  • Marcel-Peyronnie - 1948
  • Jean-Marthe - 1948
  • Massabielle - 1948
  • Kerolay - 1948
  • Steyr - 1948
  • St. Pierre Eglise - 1948
  • Edouard Goughy - 1948
  • Men Gwen - 1948
  • Laita - 1948
  • Pierre Descelliers - 1948
  • Armand Crespin - 1948
  • Ker-Ysa - 1949
  • Saint Joachim - 1949
  • Doux Frimaire - 1949
  • Patron Roger Dupuy - 1949

At least I know which one it isn't.

An Explanation of Professor A.A. Buhlmann's ZH-L16 Algorithm

by Paul Chapman

Note to new divers and potential new divers:

This information is presented for general interest. Don't be scared off by what you see here - you don't need to learn any of this to become a safe and competent scuba diver. You will however need to understand dive planning.

The following is a summary of the decompression algorithm described by Dr A.A. Buhlmann in the fourth edition of his book Tauchmedizin ( diving medicine ) published in 1995 ( only in German. ) the book contains a considerable amount of other information and is published by Springer-Verlag ISBN 3-540-58970-8. Rumor has it that at the time of writing ( November 1999 ) an English translation is being prepared for publishing, so hopefully, in due course, this document will become redundant.

The algorithm is simply a "recipe" for modeling the behavior of inert gases, which diffuse in and out of our body tissues when breathed under varying pressures. The intention is that if the recipe models the actual processes in our bodies accurately enough, it can be used to plan dives ( and other pressure exposures ) with a view to avoiding decompression sickness.
