Not sure where you got the 83 cents/pound number. Red King crab prices have been fairly steady at $4 to $5 per pound. Years ago, they have been as high as $18/lb. You might be confusing Opi or Bairdi prices (you know them as Snow Crab). They pay less, usually $1 to $2 per pound.
The 8% figure is considered one share. It can range from 6% to 10%. On some boats, the crew pays into a kitty. That kitty pays for their share of fuel, food, gear problems, etc. You start at half share. Crew typically votes on whether you are promoted to full share. On some boats, you work up 1% per year. Regardless, a ballpark figure of 8% of dockside price is pretty accurate.
Right now, you're watching only the Bristol Bay red king season. There are several seasons and several targets. If you just worked the prime season for red king, opi, and bairdi, you'd pull down $100k. That's not too shabby. You can live off that easily. Lots of guys travel. Most work in the off-season at home. Part time stuff, just to pay the bills and keep busy. That way, your $100k is just gravy.
No shortage of work in Alaska. There is a shortage of workers. I never spent a day in port that I couldn't find part-time work. One time, we were stuck in port because of mechanical problem. Waiting on a part from Caterpillar can take a long time to reach the Aleutians. We were killing time at the Elbow Room, the bar in first episode. Captain of a tramper walked in with stack of 100s and said "I'm looking for strong backs". Boom. I spent the next 3 days loading it. He paid $25/hr for first 8hrs, then $35/hr for next 8 hours. We worked three 16 hour shifts, paid in cash.
The Alaska Fund dividend check is around $1,500/year. Free money, but nothing major. Most fishermen live in Seattle or Newport, Oregon so they aren't eligible.
Scariest thing was probably making ice. Boat accumulated tons of ice on deck, which is highly dangerous. So we smashed it with baseball bats for loooong time. There's a thread somewhere on texags describing that.
I had several injuries. Only one caused by jackass crewman. He was screwing around while moving a pot on deck and it got away from him. It rolled up on me and my knee. I hurt my MCL. Didn't require surgery, but still hurts. They've said it on the show several times, the injury rate is 100%. That's true. I've never met anybody that worked for a year that didn't get hurt. Not sissy stuff either, injuries like broken bones, dislocations, concussions, knife wounds.
I put on survival suits twice during horrible storms. We had wind steady at 125 knots for two days. When waves starting stacking up, we donned our Gumby suits and sat in wheelhouse. That was not a happy day.
Responded to a couple of distress calls. We were always the second or third boat to get there, so nothing heroic. We were backups. One boat was upside down with crewmen on hull. Another boat was saving those guys. We were alongside in case they missed a guy or a rescuer fell overboard. Had on our suits then too.
Rogue waves are real and not a welcome sight. Essentially, it's 2 or 3 waves stacked on top of each other. We were steaming into Dutch Harbor in about 30ft seas. Nothing too worrisome, but not comfortable. It's like being on rollercoast, but you get used to it. Everybody was asleep except captain. Then we got ROCKED! It broke damn near everything in the boat. Fridge door ripped off, gear all over the place, everything thrown everywhere. Bunkmate was thrown out of bed and broke his nose. It looked like a yard sale. Also had water everywhere, in engine room, on deck, and in our quarters. We waded through water up to wheelhouse with our suits. But it was over in 3 seconds. Just one monster wave.
Captain didn't estimate the size. He said it was the biggest wave he'd seen in 20 years. When we got to port we surveyed the damage. Our gantry was damaged. I climbed up there and measured it. It was 65 feet above the waterline. If I had to guess, I'd say 75 foot wave.
For Aggie students, go stand right next to dorm. Look up. That's a 40 foot wave. And there's another one coming 10 seconds later. And another.
For former students, stand next to telephone pole. That's a 30 foot wave. It doens't seem impressive from car, gotta get out and get next to it.
