The GNV Atlas is a Peter Pan-class cruiseferry currently owned and operated by the Italian shipping company SNAV. She was launched on 28 October 1989 by Schichau Seebeckwerft in Bremerhaven, West Germany as Olau Britannia for Olau Line. Following the closure of Olau Line in 1994, Olau Britannia was chartered to P&O Ferries and renamed Pride of Portsmouth. From 2005 to 2017 she has been operating as SNAV Lazio between Civitavecchia, Palermo and Olbia. Concept and construction Olau Line had been owned by the Germany-based TT-Line since 1979. Under TT-Line ownership, Olau Line had acquired two purpose-built ferries from AG Weser Seebeckwerft, Olau Hollandia and Olau Britannia for their Sheerness—Vlissingen service. During the mid-80s TT-Line acquired and , enlarged versions of Olau Hollandia and Olau Britannia design also from AG Weser Seebeckwerft, for their Trelleborg—Travemünde service. During the latter half of the decade, TT-line decided to order two more ships of the Peter Pan-type, again from AG Weser Seebeckwerft in Bremerhaven, West Germany as replacements for the two Olau ships. During the build the shipyard merged with Schichau Unterweser to become Schichau Seebeckwerft. The second of these vessels was delivered in 1990 as the second Olau Britannia, replacing her older namesake. History The new Olau Hollandia and Olau Britannia were more than twice the size of the old ships with the same names, and they soon proved to be too large for the route they were built for. Due to high operating costs the ships were taken out of the German ship registry and registered in Luxembourg in January 1993, but action from the German Seamen's Union forced the ships to be re-registered in Germany just a month later. In 1994 TT-Line made plans to move the ships under Bahamian flag, but when the German Seamen's Union protested again, TT-Line decided to close down Olau Line in May 1994. Following the closure of Olau Line, TT-Line chartered the two vessels to P&O European Ferries and Olau Britannia was consequently renamed Pride of Portsmouth to fit with P&O's branding policy at the time and re-registered to the United Kingdom. Initially both Pride of Portsmouth and the renamed Pride of Le Havre entered service on the Portsmouth to Cherbourg route whilst new deeper berths were completed at Le Havre. When these were completed, P&O transferred the two to the Portsmouth to Le Havre route on 22 June 1994. This service continued largely
