If 8kts was good ~9kts is better if you are in a hurry to make #COP25 by 02DEC19. La Vagabonde is making ~200nm/day now with the potential for more, as the storm moves up the Eastern Seaboard of the United States. That LOW is literally pushing La Vagabonde along, as you can see from the wind charts. Now North of Bermuda (the little dot to the South), La Vagabonde isn’t going to waste this wind; it will ride the Storm as long and as far as it can.
This catamaran, La Vagabonde is one sturdy , well-fitted yacht. Well-fitted in the sense it is, itself, in tip-top shape. In addition, her crew has sailed the Atlantic more than once, and around the World. And finally, it was a perfect fit to take Greta and her Dad back home, and to Madrid on time.
Every hull has a hull speed, yet La Vagabonde is a catamaran and has reached boat speeds of ~22 kts in 28kts winds during its short lifetime. It can “surf”, or not displace water, similar to Malizia coming to America with Greta. It is still possible for it to travel faster than ~9kts, even faster than the true wind, in other words.
With this chart, I have zoom-in for the purpose of showing, in perspective, how much distance has been covered from NA, and how much is to go to the EU. Remember, the storm La Vagabonde is riding is heading NE up the coast, so will be with it for a few days. And Ms Greta Thunberg reports “sunshine,” via Twitter. Looks like a very happy an d good voyage to be on, for sure!
