IMO, the bevington object is an outboard powered skiff, stern to in the photo, with the outboard tilted up to clear the reef. But then again in the lengthy ROV video/still thread, I cannot make anything out of the pics shown there.
although this may drift my own thread, if anyone wants to play around with your digital photos, there is a program out there called Photofiltre. Not as capable as photoshop and watch out for add-ons if you decide to install it, but the price is right.
