We have a 70 hour tuna and tilefish trip on 140' Viking fleet out of Montauk, NY in late Aug. The trip is limited to 20 guys and it cost only $600 per person. I know the Big E burns more gas as it run fast, but the Viking runs 120-150 miles offshore for tuna at night and come back to edge of canyon each day for bottom fishing. If the Viking doesn't think they can make money on the trip, they wouldn't sail.
