Ahoy: New Horizons - The expansion we needed!

About Ahoy: Rivals & Renegades, from BoardGameGeek:

Ahoy: Rivals & Renegades is an expansion for Ahoy, featuring the Blackfish Brigade and the Shellfire Rebellion. This expansion adds two new factions to Ahoy. You can use them in place of the Bluefin Squadron and Mollusk Union in the core game, or add them all together in a two-versus-two team mode! Blackfish Brigade: Fierce orcas who menace the seas with their roving whale pod. Shellfire Rebellion: Tenacious turtles who use catapults to launch comrades far and wide.
