Haven't updated this thread since 2012. She is currently called "Impromptu" and is now up for sale. Although she was built in 2010, the yacht had a refit this year where she was fully resprayed. The interior is 490 GT keeping it under the all-important 500GT threshold. Twelve guests can be accommodated in 6 cabins. Top speed is around 20-knots using CAT marine diesels.
