How old the captain is?
|19 June 2013||Posted by Alex from Lagoon under Lagoon world|
The most frequent questions asked by future owners concerning our boats’ performance certainly are: How fast is a Lagoon catamaran? What are the maximum speed, the average speed, the engine cruising speed, the full throttle speed?
Answering these questions is not an easy task, as speed depends on a multitude of parameters* such as:
– The wind;
– The course of the boat (i.e. the boat direction relative to the axis of the wind);
– The state of the sea;
– The boat model;
– The configuration of the sails;
– The crew’s experience;
– And as we say in France: ”How old the captain is**”!
So here is a clear answer:
– Wind: 30 knots with gusts;
– Boat course: Downwind;
– State of the sea: 2 to 3 meter swell;
– Boat model: Lagoon 620;
– Sails configuration: Reefed staysail;
– Crew’s experience: Owner’s skipper training.
The speed reached at the time when the picture was taken is 19.2 knots in a surf. For those who wonder what SOG means, I speak about it here!
I would like to thank the Globe Skipper boat delivering company for sending me this picture. Their skipper training course is obviously really serious!

** Author-teacher Charles Jean explains that in a letter sent by Gustave Flaubert (famous french writer) to his sister Caroline in 1843, a trigonometry enthusiast. The author used this little story to reflect the difficulty of solving a problem via mathematical data only : “A ship sails the ocean. She left Boston with a cargo of wool and grosses 200 tons. She is bound to Le Havre. Her mainmast is broken, the cabin boy is on deck, there are 12 passengers aboard, the wind is blowing from East-North-East, the clock points to a quarter past three in the afternoon. We are in May. How old is the captain?”
