This thread is a perfect example of how expensive this fishery is. Most people don't have a clue until they do a run. Those boats posted WILL burn a 1000 per day in fuel fishing for long fins. It's not just in and out 60 miles its trolling around at 6.5-8 mph. This isn't just trolling around the sound with your old 9.9 lol. My boat is one of the smallest in the fleet and I was running 500 dollar days in fuel and oil during the shootout. The runs where very far however. The other thing mentioned is tackle for this fishery. This isn't 30lb mono a bunch of bargain bin hootchies lol. As the OP stated a very small box out the door is expensive. I just did the same thing at PNT a month ago. I don't even want to know how much money I have invested in rods, reels and tackle. Probably to the tune of 5 grand. Then you get into all the extra safety equipment etc. required for this fishery. So again, the guy's putting in the effort and money to get into this fishery are not asking a lot at 750 per crew person for the size of boats posted IMO.
It's hard finding crew members that are committed, seaworthy, understand the costs associated with the fishery, and are willing to fork out their fair share of those costs. I am fortunate to have a handful of those crew members that like to come out with me and I enjoy their company. Good luck to the OP. It sounds like a very cool trip
