DARK Class-Survivor?

Dark Scout was the only all welded aluminium Dark build by Saunders-Roe to my knowledge. I suspect the one for Japan was not welded and may even have been composite as per the British Darks and Finnish 'Vasamas'. You need to check the hull construction internally to see if it's welded aluminium. From these later photos of Scuba Doo she certainly appeas to be welded from the shrinkage wrinkles of the hull skin over the frames and along the horizontal seams. Dark Scout originally carried the typical Dark side protection 'wedges' but uniquely had transom exhausts unlike her older sister with side exhausts. If this is a survivor with any hint of ever having side exhausts she can't be Dark Scout.
