Chapter 2 introduces Honolulu and Madlantis, the game's main hubs. Exploring these areas and recruiting crew members is vital for ship upgrades and story progression. During the main quest, you'll meet Julie, a mechanic who runs GearWorks in Honolulu. She upgrades the Goromaru, and you can revisit her shop (and even recruit her!) to upgrade your cannons.
Various materials are needed for cannon upgrades, obtained by defeating enemies. These include:

Speak to Julie, select your cannon, and upgrade. Then, equip them in your ship's crew formation menu. Here are the cannon types and their upgrade requirements:
Shark Cannon

The Shark Cannon offers elemental damage and a fast reload, but lower damage. Consider prioritizing stronger cannons initially, perhaps acquiring this later to recruit Julie.
Egesta Cannon

This cannon deals consistent damage and is strategically versatile, allowing for different cannon types on each side of the Goromaru. Its dual-shot compensates for its slower reload.
