Here's a real inexpesive way to make a masthead float. Just get a few balloons, inflate them, and tie them to your masthead. A ballon with diameter of 8" will have a volume of about 250 in. ^3. This will provide bouyancy of about 9 pounds. Admittedly, the balloons aren't very aerodynamic, and they're only good for a day or two, but they're lightweight and cheap.
