Left yesterday at around 4 in the afternoon. Full moon so we were able to run 30kts to the rigs the whole way. Chunked till our hands froze off with one one yellow about 70-80 pounds. Woke up and started trolling. Picked up a wahoo at around noon and around 115 the big girl came up! Fish hit the right short and started haulin! Took most the spool off the 50. Looked back and noticed her thrashing way way behind the boat and we could see she had some shoulders. Got her to the boat in about 45 minutes our wireman took one wrap on herand she didnt like that one bit! She was still really really green and the swivel got caught up and broke her off. We estimated her at 550- 600 pounds. Fish was caught at the steps in 500ft. of water.
