Here are a few deck marks copy-pasted from my Vancouver pictures <img src="http://www.physics.helsinki.fi/~awallin/files/Image10.jpg"> (two cockatoos, an italiko and a gadget.)

Downloadable Drawings
Charles Detriche has kindly allowed me to publish two of his IOM designs "Arrow" and "Sliver". :D They are available at: http://www.helsinki.fi/~awallin/iom/ These are scanned versions of the paper drawings. I intend to produce CAD drawings of at least the hulls when I have time. A hydrostatics anal...
