Hope (or Nadeshda) was a three-masted sloop, the ex-British merchantman Leander, launched in 1799. Private Russian parties purchased her in 1802 for the first Russian circumnavigation of the world (1803-1806), and renamed her. Although it is common to see references to the "frigate Nadezhda", she was a sloop, not a frigate, and she was never a warship. Leander was launched in London in late 1799 as a c.430-ton (bm) merchant sloop. On 3 December 1799, her master, C. Anderson.In 1802 Yuri Fydorovich Lisyansky purchased Leander and another merchantman, Thames, for his planned voyage of exploration. The two vessels left England for the Baltic in May 1803, docking at Kronstadt on 5 June. There the Russians renamed Leander to Nadezhda and Thames to Neva. Czar Alexander 1 chose their names, but the two vessels were never part of the Russian navy.The two ships took part in the first Russian circumnavigation of the world, with Nadezhda serving as Admiral Krusenstern's flagship. The expedition failed, however, to achieve two of its main goals, to establish diplomatic relations with Japan, and to secure trading rights to Canton. As part of her circumnavigation she delivered RAC cargo to Kamchatka, and the first Russian embassy under Nikolai Rezanov to Japan. After visiting Japan, Nadezhda sailed to China and Macao. Nadezhda and Neva briefly reunited, then Nadezhda rounded Africa and came back across the Baltic Sea to Kronstadt, arriving 19 August 1806.In 1808 an American merchant, D. Martin, chartered Nadezhda to transport RACo cargoes from Kronstadt to New York City. During the trip, in December she became ice-locked near Denmark and was destroyed Lloyd's List reported that the "Nadeshda...is captured by the Danes, and is lost off Malmoe".

About Volvo Ocean Race 2017-2018 - Alicante port of departure.
Alicante has been the Port of Exit of the World Tour to Vela in the last four editions of what is considered the longest and toughest competition of professional sport. On October 22, 2017 the city fired the fleet that traveled more than 45,000 nautical miles around the planet with stops in eleven cities to finish in The Hague (Holland), where it ended on June 30, 2018.
Alicante has also hosted the regatta since 2010 and since 2012 the only World Museum dedicated to the Volvo Ocean Race, one of the three major events in the world of sailing together with the Olympic Games and the Copa America.
For more than 40 years, the race has exerted an almost mythical influence on some of the best navigators in history, many of whom have spent years, and even decades, trying to win it.
The regatta is located at the exact intersection between the human adventure and the pure and hard competition, which turns out to be extreme and does not forgive mistakes. In the current era, in which you compete on board of monotypes (equal boats), the only way to win is sailing with more tenacity and intelligence than your rivals. The race is won in the water, not in the design phase.
There is no economic prize for the winners, but seeing your name engraved on one of the silver rings that make up the Volvo Ocean Race trophy is a reward that is unmatched by sportsmen who grew up dreaming of emulating the feats of the legends of the regatta Heroic figures who dedicated their lives to pursue victory, such as Blake, Eric Tabarly, Conny van Rietschoten, Magnus Olsson, Grant Dalton or Ian Walker.
The concept of the regatta is simple: it is the definitive ocean marathon, a race around the world in the anti-clockwise direction in constant pursuit of your rivals in which the best sailors in the world measure their forces across the oceans wildest of the globe.
The stamp shows a photograph of a moment of the competition where several boats appear on the high seas.

The yacht on the right is the BRUNEL.

Upwind sail area 468m² mainsail and 296m² mainsail and working jib. Downwind 578m²’

TURN THE TIDE ON PLASTIC was launched in 2014 as VESTA WIND and is a Volvo Ocean 65 yacht.
As Team Vestas Wind, she finished seventh in the 2014–15 Volvo Ocean Race skippered by Chris Nicholson.

On November 30th 2014, during a night navigation, the yacht grounded on a coral atoll of St. Brandon. This happened 10 days after leaving Cape Town, on the way to Abu Dhabi. The yacht was damaged and repaired the race for the last 2 legs. The grounding was because the atoll was not visible on the low scale chart. The crew was rescued by the Mauritius coast guard the next morning. The cause of the grounding was a combination of human error and the features of the navigation software. The software did not show the atoll on the route planning display at low or medium zoom levels, while the atoll would have been shown in the navigation chart display at those zoom levels. The crew on watch did not notice there was a wrong chart display on.

Following the race, the boat was refitted for the 2017–18 Volvo Ocean Race and renamed in TURN THE TIDE ON PLASTIC. Sailing under the flag of the United Naties.
She finished under skipper Dee Caffari 6th in the 2017-18 Volvo Ocean Race.
