Not bad. If what I gather from a quick browse from the site, it's sort of a SCUBA-blog-review type thing for you.
One thing I can tell you from working on tons of websites and media, UPDATE CONTENT REGULARLY. Keep on a solid schedule for releasing content, and if you can't do that, you'll lose visits fast.
Also, a news update feed type thing would be convenient to see on the front page and also streamline the look of the site. Also, run spell check through the whole thing.
That disclaimer HAS to go. You aren't teaching SCUBA or offering any tutorial videos, so putting a disclaimer up would be useless waste of space.
If you need any help regarding the design or media of the website, or would like some graphics let me know. I wouldn't charge you for anything.
