Just spoke to my friend again and here's the story of the fight:
For the first 1 1/2 hours the fish went deep (approx. 800ft), stayed there and wouldn't budge. He locked down the drag (80lb tackle) and tried to plane it up whilst retrieving line. This worked and they got him to the boat three times, though each dive became shallower. The last time, they managed to get a Flying Gaff into him and he went beserk and was actually towing the boat backwards at one point.
By the time they boated him the gaff had torn a huge hole in his belly and some of his guts were missing. So maybe he would have weighed a few pounds more.
