"The days are getting shorter and Scarlet is getting closer. At almost 200 days at sea and over 7,000km flown she is over 95% across the Atlantic and less than 100km to the Spanish EEZ. It is simply amazing to look back over the past 6 months and see literally how far we have come. Preparations are under way for her recovery mission as well as for her trip home. It's a very busy time for everyone back at Rutgers.

If that wasn't enough, we also have 5 other gliders out to sea with a 6th on the way. Last week RU15 was successfully recovered after a stellar flight down the MURI line with the new BAM sensor on board. During her recovery we also helped deploy the "Blue Hen" from the University of Delaware. The four gliders off the New Jersey Coast make up the Observing System Simulation Experiment team. All four gliders have been flying well and Oscar has been keeping us up to date with his blog entries, which can be seen here. In addition to Scarlet and the OSSE team, Drake is holding steady and we continue to find deep gliders easier to pilot. They are more ship like than drifter and easier to fly from point to point. Lastly, this week will be the first Antarctic glider deployment. Sometime between Wednesday and Friday we are planning on deploying RU25, which is our deep glider. Bringing our weekend total back up to 7 gliders! For additional news from Antarctica check out the blog. "

So, a glider already crossed the Atlantic. But no sailing robot yet.
What about a sailing glider? :)
Protei design so far is mostly submersed, very similar to a glider - a sail would probably be a stronger propulsion supplier than a propeller in the water anyway. The trajectory here shows that they really chose the option of low energy being very dependent on currents. More energy = more control = more useful for research.
But I'm very impressed by this already :)
