Two works by the German sculptor Karsten Klingbeil (1925–2016). The Berlin sculptor Karsten Klingbeil created this sculpture of a fisherman sitting on a lobster trap at the marina in Quiberon Port Haliguen, gazing out to sea. Karsten Klingbeil, of German descent, created it and donated it to the town. It is very personal, as the sculptor gave the fisherman his own features. He gazes across the harbor entrance at the sculpture of a beautiful mermaid who is just freeing herself from a fishing net.

Real racing boats are often moored here. Lots of speed, little comfort.
