We did the 5 hr halibut trip, We had 2 boats. So we were into this experience for $4k.
I am also a licensed fishing guide in WI, and did a lot of deep sea fishing when we lived in FL for 7 years. So I probably have high expectations.
The good:
1. Nice rigs- the boats are good quality boats and well laid out for this kind of fishing. They can handle big water, have a reasonable toilet, and a nice closed cabin if you get cold or want to get out of the weather (this is probably true for most all charter groups too).
2. Nice people- the captains on both of our boats were really nice and interesting people. They were cordial and happy to talk about Alaska and all that goes on in their world in the estuary.
3. Reasonably good equipment- the rods and reels are just fine and the first mate was careful to sharpen hooks before we fished- something that is easy to neglect. A sharp hook at 315 feet is pretty important because of the delay in the hook set and the long distance between you and the fish. They use braided line which doesn't stretch and conducts feel well.
4. beautiful country and wildlife - Bumping into wildlife is normal. You can see a whale and other thigs on fishing trips so bring binoculars!
5. There are fish- it's a good estuary and there are definitely good fish populations.
6. The deck/first mate was really personable and talked with us a good bit.
The not awesome:
1. You are likely to fish in over 200 ft of water without electric reels. We were in about 315 ft. This will tire you out if you are only checking bait reeling up a 24 ounce weight. Make sure to ask the deck hand how to reel with both hands so you can switch when reeling up. Some guides have electric reels if they fish Halibut a lot. It doesn't make as much sense for guides switching back and forth between salmon and Halibut.
2. We didn't work hard to get on fish- We went out to one spot, anchored up and stayed there the whole time we fished. I get that it's 315 ft of anchor to pull up, but I would never do this to one of my clients or anyone I took fishing. If the fish aren't there, I'm moving. This is true for all species I've fished. This is also true for people I know that fish halibut on the AK panhandle. For me this is a BIG issue, and it's not something you can rally negotiate on the boat. My wife broached the topic and our captain said "nope. This is our spot. We got fish there yesterday." But we had two boats on a spot, and reading the contours, we were in the inferior location. I was sure to tell the captain we did not want to stay together at the expense of the spot we were fishing on. Productive fishing zones are often small, and it seemed like we were just not in a productive place. I found this really disappointing. Even if we had fished one more spot, I would have felt a lot better about it.
3. It's a drag not to be able to do anything with your fish if you're on a cruise ship. You can have it processed and shipped, but it's REALLY expensive to have it overnighted home.
4. Guides do a good bit of the fish hooking- the method used is to really load the hooks with dead bait. This makes the bait more enticing, but the hook harder to drive into the fish because the bait is partly in the way. So setting the hook right is clearly important, and the guides do it well. But they can't get on every bite, and it means you aren't doing the most exciting part of fishing when they are doing it. They also didn't give a lot of instruction on this part.
I would not do this again as a function of cost. At not cost, it was fun and I'd do it as an excursion. But if I could go back, I would have only done one excursion and spent it all my money on the helicopter to the glacier. And that's saying a lot. I'm a diehard fisherman.
