I also added weather and wave observations from the API of the Finnish Meteorological Institute. Clicking on a track brings up these details, provided the closest weather stations and wave buoys are within 30 nautical miles from the track. They are therefore only approximations, and can vary from the conditions actually experienced on the boat, depending on its location relative to the stations/buoys and nearby islands.

It should also be noted that the tracking accuracy of Moves is lower than that of proper chart plotters, which is only natural considering battery consumption. There are also clear errors when close to shore, as Moves has a tendency to place the location on known roads. Tracks and all values should therefore be taken with a grain of salt.

Zooming in on the tracks brings back memories from all those legs and marinas, of great sailing and even better company. It lets me relive moments like these.

Great story of a great race.

Pretty cool visualization.

Suddenly Aldridge was flying backward, tumbling across the deck toward the back of the boat, which was wide open, just a flat, slick ramp leading straight into the black ocean a few inches below. Aldridge grabbed for the side of the boat as it went past, his fingertips missing it by inches. The water hit him like a slap. He went under, took in a mouthful of Atlantic Ocean and then surfaced, sputtering. He yelled as loud as he could, hoping to wake Sosinski, who was asleep on a bunk below the front deck. But the diesel engine was too loud, and the Anna Mary, on autopilot, moving due south at six and a half knots, was already out of reach, its navigation lights receding into the night. Aldridge shouted once more, panic rising in his throat, and then silence descended. He was alone in the darkness.

It’s hard to explain, but when a man’s within sight of sailing it’s as though he’s already gone, and the distance between him and those he’s leaving behind widens by the moment.

If you want to build a ship, don’t drum up people to collect wood and don’t assign them tasks and work, but rather teach them to long for the endless immensity of the sea.

A school library without this book is incomplete. It should be part of the education of every English or American boy. — Boys who do not like this book ought to be drowned at once.

I agree.
