The best experience I had was I played a healerbrand with a viper scourge then the rest doesn't matter but DPS. I found that's the best combo because healerbrand offers lots of aegis heals and boons while a viper scourge uses the Epi and adds closeby are just deadmeats, on the other hand the scourge offers barriers when doing shards, a major relief when the healer is on the cooldowns. And the rest DPS monsters just do what they are born to do, fast and neat. Even with birds, slippery, or outflanked. This boss cannot be full DPS unless you are a group of SnowCrows. Aegis actually can counter the shark, and the boss's wind blow (not the side blows), then one thing to consider is, if your pug cannot do good with the wind blows, the best way is let it blow you from the middle of the ship, just the adds but you won't get down to the water and get eaten lol.
