I saw her last year at Bursledon. She was in a bit of a state though. She is owned by the same guy who owns Ice Maiden and I think he has a website so you may find it through Google.
She was based in Milford Haven, (the marina nearest the railway station) last time I saw her. Try "http://www.maiden-international.com/" for info. The usual tourist-trap stuff [ARC, Fastnet, Round The Island... ] is typically over-priced but delivery sailing to and from her South Wales base was about £25/day.
