The sailors journey

On October 19, 2014, a brave sailor determinedly set out to sea. His goal was to sail around the world alone, without the help of any fossil fuel or additional supplies, other than what he brought with him for the entire 50,000 nautical mile journey. What would a sailor bring along in order to survive such an ordeal? This sailor, the Italian Matteo Miceli, decided on a fishing rod, two chickens, a plot of dirt to grow vegetables, a machine to desalinate drinking water and three Leica Geosystems’ GNSS GR25 receivers and three Leica AS10 antennae.

世界各地航行前后垫teo’s motivation for undertaking this journey, however he was just one member of a group working together on the project, “Rome Ocean World”, and they had other goals as well, such as being the first sailboat to accurately record the water and boat’s movement throughout the trip using GNSS technology.

At the end of the journey, Professors Paolo di Girolamo and Mattia Crespi from the University of Rome and Allessandro Pezzoli from Polytechnic Turin, would analyse the data that would hopefully validate the UK-based MET (meteorology) numerical models by calculating wave heights on the Eco40 route; improve the structural design of the Class 40 boat by calculating the dynamic stress and durability of the vessel during the trip and finally, to produce a polar diagram of the boat’s speed after recording wave characteristics, which will be especially useful for future Class 40 racing boats.

从罗马附近的Di Traiano港口起航后，Matteo有三天的天气，使他能够与他的团队一起回到罗马，他每天接触。然而，当冈萨洛飓风的残余物以大雨和大风的狂风袭击地中海时，他很快就面临着许多海洋道道测试中的第一次。After several intense and expectant hours of lost contact, the Eco40 team received an automatic data transmission on the boat’s position, confirming it survived 80 km/h (50 mph) winds and six metre (20 feet) high waves, and that it was on its way towards Gilbratar.

这场风暴使Eco40，水手和他的鸡的状况不佳。花园被毁了，里面充满了咸水和蔬菜死亡。鸡已经受到创伤，一段时间不会产卵，而且海仍然是如此暴风雨，以至于钓鱼是不可能的。仅在这种紧急情况下，水手将100袋冷冻食品放在船上，Matteo在100 g（0.22磅）的碳水化合物中幸存了几天暴风雨命中。

After the storm passed, Matteo had time to think. A professional sailor by trade, it was a challenge for him to stop and fix damaged boat parts. Matteo wanted to push the high-performance Eco40 to set record speeds but instead, he had to wait, either for the repairs to dry, or for wind. The sailor had time on his hands and was confronted with the commitment he had set for himself when agreeing to take part in this adventure. The lack of wind got to him, and even with the daily tasks of running a boat, data collecting or just plain day-to-day survival, he was sometimes lonely and often doubtful. Luckily the chickens, whom he nicknamed Blondie and Brunette, needed encouragement to lay eggs and they became fast companions. He also had daily support from his Facebook fans to cheer him.

Data was collected by the Leica GR25 GNSS receiver and the Leica AS10 antenna and sent via GEO stationary satellites without any problems. And the Eco40’s hydro, wind and solar energies supplied as planned. The real problems of this journey were more mundane concerning human nature and the purpose of existence. For instance: The sailor could only get a few hours’ sleep before being awakened by gusts of wind, which caused severe jolting of the boat; or the auto-pilot’s voice waking him to tell him of some route change. If he could sleep more than 20 minutes at a stretch, he had to nevertheless keep his eye on the barometer since his life depended on knowing if a storm was approaching. Food was of course always a big concern – just to catch a fish or grow bean sprouts on a wet paper towel were major victories. Fish, sprouts or maybe an egg, this was Matteo’s diet for months – if he was lucky – and he was happy to have it. The companionship of Blondie and Brunette helped to distract Matteo from loneliness and it was a sad day for the sailor when, for no apparant reason, Blondie passed away. Sometimes he was lucky enough to be accompanied by birds or dolphins, however he was alone on this journey and for him, it was the little things in life that mattered most.

Unpredictable weather patterns were also a major concern. One night, a sudden wind change caused the boat to do a death roll. Matteo woke to an almost capsized boat, halfway under water. Alone, in the dark and with water rushing into the cabin, the sailor had to think fast. It’s a situation many of us wouldn’t want to be in. Sometimes the boat sat in fog for days on end. Another time, a massive wave hit the boat while the sailor slept, causing a very bad head injury and severe anxiety. Nonetheless, Matteo had to go on tending the boat in order to survive.

He journeyed through cold polar air and icy waters of the Sub Antarctic, with the unseen dangers of icebergs looming ahead. Severe waters for a boat to be in and it was during this part of the trip that the Eco40 lost its auto-pilot. It was damaged along with much of his electrical equipment after being struck by lightning. Luckily, his team (Cecilia Angelelli, Valerio Brinati, Allesandro Farina with Leica Geosystems’ technical support Pierpaolo Pecoraro) “walked” him through this part of the journey, restoring his PC software, the boat’s instruments and helping with battery problems via satellite calls. This damage needed to be rectified as quickly as possible, even if only temporarily.

With icy rain and freezing temperatures, Matteo remained strong. But stress took its toll on the sailor. At this point, he had been sailing alone for over 100 days. Lack of sleep, too little food and constant cold had its effect. He endured near-fatal storms and heavily damaged electrical equipment – and was very worried. This was certainly a bleak part of his journey – and it was somewhat noticeable in his communications. He started eating chicken feed to survive and had to pull out his own tooth. Yet, he did what he had to – to survive.

In early March, Matteo discovered the Eco40’s rudder under 300 litres (80 gallons) of water. These bushings holding the rudder and almost caused the journey's end however Matteo had managed to repair them. This time bolts holding the boat's keel in place caused Matteo to lose the keel in March, on Friday the 13th, and wind capsized the Eco40. Alarm systems warned Matteo and alerted the Italian Coast Guard, who then sent word to the nearby merchant ship, Aramon, to pick up the sailor, who patiently waited in an inflatable raft he managed to fish out of the Eco40 before it sank. The sailor also tried to rescue Brunette but sadly, he was too late.

Yet Matteo was lucky. The area where the boat capsized was known for its calm waters and he had, eight hours earlier, closed the double-crossing of the equator. He accomplished what he had set out to do. He rounded the Cape of Good Hope, Cape Leeuwin and Cape Horn; crossed the equator twice and crossed all the meridians he planned to. The Eco40 travelled, from start to its tragic finish, roughly 25,000 nautical miles (approx. 46,000 km /28,600 mi) and at the time of its capsizing, was approximately 965 kilometres (600 miles) from the Brazilian Coast.

Matteo also succeeded in accomplishing his goal to sail non-stop, all alone, around the world, from point of departure to point of arrival and maneuvered the Eco40 several times across oceans for 112.4 days at an average speed of 7.4 knots. After being rescued by the Aramon, Matteo was pampered by its crew. He had lost more than 30 kilograms (66 pounds) and spent his time relaxing, eating and making use of the ship’s gym.

马特奥Miceli一rrived back in Italy on March 19th at Rome’s Fiumicino Airport. Upon seeing the professors for the first time since he left Rome, the sailor presented them with the all the SD cards containing the data that the receivers collected during the trip with the exception of the very last cards that were still in the GR25 receivers as the ship went down. These cards were last exchanged on February 28, when the Eco40 was off the Argentinian Coast.

教授和水手几乎立即开始计划如何恢复船。卫星跟踪器仍在从船上发出信号，该船只在水下流中漂流。追踪器的电池很快就会空了，因此只有很少的时间可以腾出时间，团队飞回了巴西，组织了一艘船进行营救，同时还计划稳定，一旦重新铺设了Eco40的运输。不幸的是，在到达恢复区域前约30小时，跟踪器停止发送信号。该地区太大而无法搜索，4月4日，搜查被暂停，车队回家。

但是，旅程还没有结束。就在七天前，言语传到了教授，一艘西班牙渔船发现了被认为是浮出水面的Eco40，该船只漂浮在巴西海岸，距团队期望找到这艘船350海里。拍摄了一张照片并将其发布在Twitter上。

Unfortunately since then, no one kept track of its position, but according to the professors' calculations, it was headed out to sea …
下一个什么?旅程还在继续。敬请期待……
Good winds to all!
