The Bright family on their cutter-rigged sloop Yindee Plus left the UK in July 2009 and cruised around the world for seven years, returning to the UK in 2016. Their twin sons were six years old when they left. Their blog has lots of interesting reports from the 45 countries they visited with blogs by the twin boys as well. There are also useful reviews of marine products and services.
Their boat was sold in 2018 and the Bright family now live ashore.
