Ship upgrades and utility tools
Combat encounters and survival reward sailors with resources to strengthen their floating fortress. By using keys 5 – 7, captains can allocate attribute points directly into ship capabilities to improve survivability against incoming fire. Additionally, players can toggle between different equipment using keys 1 – 3, switching between artillery weaponry for combat and a rod for maritime harvesting. Balancing offensive readiness with timely stat enhancements is essential to withstand prolonged ocean skirmishes.
Tips and strategy

- Keep moving during exchanges: A stationary craft presents an easy target for enemy cannon broadsides.
- Invest in stat upgrades early: Allocating points using keys 5 – 7 immediately boosts your chances in sudden encounters.
- Check your surroundings constantly: Hostile vessels can approach rapidly from blind spots while you engage another target.
