Sailing in Turku Archipelago by Visit Finland, via Flickr - Finland has, depending on the method used, somewhere between 55,000 and 188,000 lakes, and nearly 3000 miles (4830 km) of coastline, off which lie more than 80,000 islands including the Åland archipelago. Cruising opportunities are infinite, either through the many islands or on the lakes, the larger of which are navigable.
Interesting lighting idea. Projection on scrim? Could move at the end? (The Ghostship (by Torben Höhn))
