If you use the 3/16 aluminum you won't need any extra support for a 14" span.

Buy a rivet tool and you'll be set for aluminum. It's not hard to work with but if you do go with wood do not use nails, use screws only.
Get on "tiny boat nation.com" and see what those guys are doing. I would use aluminum angle and square tubing for the frame and 3/16 aluminum plate for the deck.
