Kooltrak Marketing Director Cornelia Stenz recently sailed a yacht  around the island of Elba in the Mediterranean, departing from the Italian port of Piambino and sailing as far as Corsica. Naturally she took the opportunity to fit Kooltrak data loggers around the boat, and brought back temperature records made during the trip.

On Corsica, Cornelia overnighted in the old pirate harbour of Bastia.  This harbour and its walls jetties and buildings are built from huge stone blocks, and doesn't look to have changed in hundreds of years. But amazingly enough, modern engineers needing to run a highway along the coast have tunneled beneath the town and harbour without disturbing anything, and traffic runs unseen and unheard beneath the harbour while the medieval town slumbers on in the sun, lost in its own time.

Kooltrak data loggers were located on the yacht in the galley, the engine room, in Cornelia's cabin, and on her wristwatch (see photo above). The logger on her wrist went everywhere, and also records the water temperature when she went swimming.

The following graphs, produced by Kooltrak 1.3.7 on Cornelia's return to the office, show what temperature conditions were like on the boat.
