OK, I digested that, and got my answer from SSV:
"* Offer the most thorough in-water hull inspection service"

I have never inspected from a submersible, but have done so with SCUBA. For me, the sub would not replace the intimacy I associate with grabbing onto gear or laying hands on the antifouled surface of a hull.
Wish you the best of course...
I can see contractors such as yourself being hired to patrol major harbor waters sometime in the future, but I can also see small, inexpensive (well relatively) robotically guided surveillance subs being implemented in the not too distant future.
Harbors like Norfolk come to mind for implementation of such subsurface assets...
