The Jackdaw is Edward Kenway's brig and the player's primary vessel in Assassin's Creed Black Flag Resynced. Naval gameplay has been rebuilt alongside the rest of the game, with new weapons, a more dynamic enemy ship ecosystem, reworked side activities, optional companions, and significantly expanded ocean exploration.

Naval Combat
The Jackdaw gains two new secondary weapons: shrapnel barrels that damage enemy sails and reduce their maneuverability, and 8-pounders that open weakpoints in enemy hulls for follow-up attacks. Both weapons expand the tactical options available in ship-to-ship combat. Enhanced alternate fire modes are available across the Jackdaw's armament, allowing players to switch between different approaches mid-engagement.
Enemy Ship AI and Alliances
Enemy ships in Resynced maintain alliance and enmity relationships with each other. These relationships affect how ships behave in the open ocean, including their willingness to assist or attack other ships, their patrol patterns, and the loadouts they carry. A ship's allegiances are part of its identity rather than a static label.
Kenway's Fleet
Kenway's Fleet, the system that lets Edward assign captured ships to a secondary fleet, has been reworked in Resynced. The updated system generates passive income over time, giving players a meaningful economic return from fleet management without requiring constant attention.
The Playas
The Playas, which are the island stops scattered across the Caribbean, have been reworked with new rewards and encounters. These locations provide reasons to explore beyond major city hubs and tie into the larger naval and exploration loops.
Ship Pets
Players can recruit a pet to sail with the Jackdaw. Two options are available: a cat or a monkey. Ship pets are a cosmetic and companionship feature that adds personality to the Jackdaw without affecting combat stats.
Underwater Exploration
Underwater exploration has been expanded in Resynced. The rebuilt Anvil engine's water rendering and simulation create a more detailed and reactive ocean environment, and expanded diving sections give players more to discover beneath the surface.
Dynamic Weather
The Anvil engine's atmosphere system drives dynamic weather across the open ocean. Winds, wave heights, and storms change in real time and affect ship handling in ways that require adjustment during navigation and combat. Calm seas and squalls behave differently, and sailing into a storm is a tactically different proposition than an open engagement in clear conditions. Destructible environmental objects in the world also interact with weather and combat.
