Rowing past Mercury marina I spotted an unusual craft, which turned out to be the Derek Kelsall designed trimaran Freedom of Norwich.
From what I've read she was home built by a doctor some 35 years ago and certainly for a while was based in Chichester harbour.
Interesting detail on the struts which link the hulls, there are two circular section struts forming a triangulation covered a separate deck section above the upper member. It's looks very strong and after 35 odd tears seems to be holding up well given the significant forces which apply there.
Great to see a unique piece of our recent sailing history up close, I'd love to go for a sail.
