Great report! And very, very smart of you to recognize wrong thinking on your part. Bluefin fishing is very different from all other tuna fishing except really huge yellowfin. Hundred pound bluefin are every bit as tough as anything else with fifty more pounds to play with. Sixty pounders break our hearts regularly. Teamwork is the way to go. Sharing hookups is good karma, and accepting a hand-off is also a positive vibe.
And for your next trip, try hard to get into one of the double bunk rooms like B or C or E or F. Trust me, you will be even happier.
