Boat trips to Ven with friends and colleagues

Summer 2000 with Jack Dongarra and Martin Gander on board "Den Gule Enke" (The Yellow Widow), a 28" Bianca sailboat. Jack took the nice pictures.

The Captain and Chef almost blinded by the sun. (Click on the picture to see a large version)
Martin having gotten to the cheese and had too much wine??
