yes they have been geeting them out near the hooter south of the vineyard, but this are is refered to as the islands (south shore is hingham to plymouth etc.)
Blue Oyster, Baitcaster and I hit that area yesterday and it was quite, but they have been showing in that area from time to time. Give it a shot, there were some bigger bluefish out that way so if you don't see the tuna at least there is something there to play with.
