I weighed the BlackCat tonight on the scale at the post office. Came in at 13.6 oz. without tie-out lines.
I still have a LITTLE bit of stitching to finish, plus seam sealing, so those aren't included in the weight. I can't imagine they'll add much, though. I expect it'll end up around 13.8 oz., the same weight as Brian's Deluxe model.
Not bad, considering the BlackCat is a foot longer and two feet wider than the Deluxe. Of course, I didn't use the really nice grosgrain trim or the Kevlar corner reinforcements that Brian does, either. But I'm happy with it!
