L.L.  Bean

Answer 2

Pretty much every sporting goods store will have some version of a cupholder for boats.  Some attach with suction cups, some with a hook that hangs over the gunnel, some are screwed to the gunnel.

Walmart and Kmart carry them in the summer, Sport Chalet, Big 5, Gander Mountain, Cabelas, Bass Pro Shops, Boater's World, Overton's, West Marine...
