Silversea Cruises has chartered a ship for late summer to the Kingdom of Saudi Arabia, four months after the royal state invested more than $400m in rival Carnival Corp.

The Royal Caribbean Group brand has fixed 608-berth Silver Spirit (built 2009) for two months starting 27 August to Red Sea Cruises, an initiative backed by Saudi Arabia's Private Investment Fund.

The fund plans to use the ship to offer short cruises throughout the kingdom to the Saudi market as part of Saudi Tourism Authority's (STA)"Saudi Summer" programme.
