Well, I'll be. That hull number is, indeed, for a '05 260DA. Honestly, I thought it was going to come back as a 240DA and a previous owner had renamed the boat! It's also the first '05-'09 260DA that I've seen with the tank up forward. I think B Arrington might have a good explanation for it, as it he pointed out. FYI, '99-'04 260DA's had the tank in the bilge... well, at least every one I've ever seen!
