Unknown cat

[Bluevelvet]

Hi first post on this forum. I saw a cat today in Cartagena Marina Spain and really liked the look of her. Her name was Dr Martin or Dr martun with a German flag around 35-38 ft, she had a aft cockpit that ran across the full width of the boat and had three separate entrance ways, it looked like the bridge deck cabin was self contained, she was steered by a connected bar, had transom rudders that lifted. Wish I had taken a picture.To my eyes a very sea going boat. Can any one help with model type. Thanks
