This unusual vessel was developed in the middle of the 20th century and manufactured until the 1970s.
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes.
Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.
The one seen here, which resides in a ship graveyard near Perm, was used in a fleet along the Russian waterways.
Visitors hiking along this 133 mile circular trial, which begins and ends in Killarney and can be completed in nine days, will eventually pass a stone structure that has been almost completely reclaimed by the surrounding forest.
Its current state tells of story how long it's been abandoned, as well as hinting at how old it truly is and what it must've been like when it was still inhabited.
It makes sense that someone would build a home amongst such stunning scenery, but there's no official record of who lived there or why it was left.
Guido Galletti created this amazing figure, whose original cast now sits underwater.
Various other casts of the statue are located in other places worldwide. This one was placed off San Fruttuoso, between Camogli and Portofino on the Italian Riviera on August 22, 1954.
It rests at 56 feet deep and stands at around 8 feet tall. Galletti used the statue and its placement to depict Christ offering a benediction of peace, with his head and hands raised skyward.
Back in 2003, it was taken out of the water, restored, and put back a year later with a new base.
