Avoid the Hydro Cannon attacks. Use the Dragonator as often as possible (and don't miss!). Use all of the Ballista shots that each of you can collect from the item piles near the two Ballistas. Give yourself Health+50 through the Felyne meals. Keep your health near maximum. Bring Shakalakas with healing dancing abilities. If Goldbeard swims unnaturally up to the top, it's going to fire its Hydro Cannon.

Not all of this may be useful, but I hope that some of it is.
