I have worked in the Bering Sea and I know the Alaskan fishing business so please listen to me son...
Very simply, there is NO place up in Alaska for some 20 something green kid on a fishing vessel...especially a crabber! The skippers of those boats DO NOT want a guy like you. Any of the nonsense you have seen on Deadliest Catch is only made up for the show. Fishing in Alaska is NOTHING like what you see on that stupid effing goddamned made for cable bullshit. What you are seeing there is fucking make-believe "reality TV"! Deadliest Catch is the worst thing to have ever happened to Dutch Harbor and the REAL fishermen of the Bering (not "baring") Sea!
The only thing you can do is like every other stupid kid without an "in" who wants to become a roughneck Alaska fisherman is to go to work for one of the seafood processing companies like Trident, Icicle, Unisea, etc... as a processor working on the "slime line" for long miserable hours at pathetically low wages but let the master or mate or deck boss know that you want to become a deckhand and if you show that you are a buttkicker out there in the plant, then they'll see a guy who is worth moving out to the deck. Then you'll have to do it all over again out there but now it will be in the wind and snow and numbing cold. You'll have to do horrible jobs like offloading the crabbers by climbing down into the tanks(holds) of the boats, crouching for hours and then literally hand tossing the live crabs into a big brailer net. If you survive that for a couple of seasons, then you might to be seen by the crews of those crab boats as an asskicking deckhand and maybe...just maybe one of those guys one day would say "hey, I hear that so and so boat needs a new hand...do you want be to tell them you're interested?" You are looking at a minimum of four long years to get there "IF" you're lucky!
FOR GOD'S SAKE....PLEASE DO NOT LEAVE YOUR CURRENT JOB. DO NOT SPEND MONEY ON SOME "HEADHUNTER" TO GET YOU A FISHING JOB IN ALASKA. DO NOT MOVE TO ALASKA. DO NOT MOVE TO SEATTLE EVEN!
Do this...Google "Alaska Seafood Processing Company" and look at the newhire level job descriptions of each company. Then decide if you still want to chase something that is only a dream and in no way reality. If you do, then come back here and I'll give you some pointers on how to make your track to the goal line a little easier for you, but read everything you can first so when you come back you can ask informed and not stupid pointless questions!
If I have managed to avoid you doing anything horribly stupid then I will know that I have done something truly useful here in all this time other that to be the resident malcontent always yelling at all the "goddamned kids to stay off my effing lawn...bunch of lousy punks!"
