The challenge: make this thing here look good and make sense. In looking up what other scuba websites, I found that design really isn't a priority for many of them. Look no further than
www.stcroixscuba.com:

That's pretty par for the course. Bubbles, blue, red/white flag, photos of people diving, photos of sharks/fish/turtles/coral reefs/palm trees, and BAD TYPE are all top scuba web design fetishes as far as I can tell.
Here's more scuba-related links:

SeaWorldand now for some pretty websites:
Virgin Mobile Music FestivalWe really like the dynamic graphics on the homepage, plus it's nice that you don't have to click on anything to see the line up, which is probably the number one thing people want to know.
This American Lifeso simple - doesn't hide anything from you or distract you. i love it.
Delicious Design Leagueglobal nav really pops here, design is simple and bold.
Fire Belly DesignTheir homepage is basically a very clean, simple newsletter.
Slow Food USAHomepage has blog highlights, news, events, and lots of beautiful pictures that don't distract. You don't have to search for the important news items.
The MothNice type and color palette, global nav already shows some of the breakdown, which is nice if you want to get straight to a particular show.
3stpictures rather than global nav: works good for showing images. homepage becomes a grayed-out background when you click on something.
