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 return to 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 the cannon you wish to upgrade, and equip them via the ship's crew formation menu. Here's a breakdown of the cannon types and their upgrade requirements:
Shark Cannon

The Shark Cannon offers elemental damage and a fast reload, but lower damage output. Consider this a later upgrade, perhaps prioritizing others first.
Egesta Cannon

This cannon deals slow, consistent damage, making it a strategic choice, especially if you equip different cannon types on each side of the Goromaru for varied damage types. Its dual-shot compensates for its slower reload.

The Super Laser Cannon is the ultimate upgrade, boasting incredible power and range. It requires rare components, making it a late-game acquisition, perfect for challenging battles in the Pirate Coliseum and against the Devil Pirates.
