Marchenko, unexperienced in building or operating sail boats, inspired by the "Pirates of the Caribbean" movie, has spent his free time on the ship for four years to achieve his childhood dreams of building a boat. He also uses the vessel as a mini-hotel for tourists, who wish to spend time in a wild nature place located in Siberian Taiga district between the Sayano-Shushenskaya and the Maynskaya hydroelectric power stations.

A Chinese man helps local residents carry an under-construction boat that will be used in sea cucumber fishing in Dublin, March 21, 2014. As evening falls over Sierra Leone's Banana Island archipelago, bats stream from their beachside roosts to circle in their thousands over the jungle village of Dublin. Below them a struggle is playing out over an unexpected commodity - the lowly sea cucumber, a fleshy, sausage-shaped creature that scavenges for food on the seabed. While the Banana Islanders have no use for sea cucumbers, in China they are prized for their medicinal properties and as a natural aphrodisiac. Picture taken March 21, 2014.

Men work on a boat on the river Clyde during a misty morning in Glasgow, Scotland January 14, 2014. The British shipbuilding industry has been through a turbulent time after defence contractor BAE Systems announced in November that it planned to lay off 1,775 ship workers across the UK. The cuts signal the end of more than 500 years of shipbuilding in Portsmouth on England's south coast. BAE is set to continue constructing ships in Glasgow, but showy entertainment venues, museums and new housing blocks have replaced many of the shipyards that once lined the city’s famous River Clyde. Long gone are the days when the area was an industrial powerhouse producing around a fifth of the world's ships. Now Glasgow promotes itself instead as a financial and commercial hub – although it still struggles with high unemployment. Picture taken January 14, 2014.

The Panama Canal Authority said late on Wednesday that the Spanish-led consortium expanding the major world waterway had agreed to restart work first thing on Thursday after a two-week stoppage. While workers gathered at the site on Thursday, works were still idle on Thursday afternoon.
