What kind of design do you prefer? Funny or some serious?

We are really open to both, but considering it is a boat, we would probably want some thing fun and light (i.e. a guy pumping fuel into the letters) as opposed to dark and serious (i.e. an oil spill in the water with birds covered in oil)!

For the "RiVA House" idea, there is probably less to work with. We really want it to have the RVA logo look (see http://rvacreates.com/gallery.php for examples) but somehow get the "i" between the R and V. Maybe making the i something nautical, such as a piling with a seagull on it, or a buoy... just some thoughts.

Ok, thanks... :)

Can you tell me what is the sticker size in inches or feet? Also do you know what process will be used to print the sticker?

It's really more of a vinyl decal. The space we have is roughly 58 inches long by 20 inches tall. There will be transparent background so that the white of the boat shows through.
