You might want too also use some of my other beach videos from my nudebeachmovies site under BVCash

As far as the term Beach Tube, all i can picture is a rubber innertube at the beach for some reason.
It's a good name for branding tho.
I would definitely put a good variety of content on there from other beach sites. (hit me up if you need a list)
Make it a kick ass beach tube site.
beach girls
thong girls
candid beach
bikini girls
girls in thongs
these are the types of words and phrases you want to focus on seo wise
also,
if you want anything special made up, like a special banner or logo just ask and I will make you one.
Cheers,
BV
