The folks at Russell Marine ( Acle ) Ltd ta Marine Tech were helpful but had little further information: Russell Marine own Acle Marina which was built on the former Easticks Yacht Station site. Most of the Easticks records were believed destroyed in a fire.
I also got a reply from John White the - Deben and Orford Haven Honourary Port Pilot suggesting Gesine had been down at Felixstowe Ferry around 25 years ago. I am looking forward to receiving more information.
So .. was my yacht formerly called Gesine?
