Islebound

From Board Game Geek:

Set sail in a mystical archipelago filled with bustling towns, sea monsters, pirates, and gold! Compete to build the best sea-faring nation with up to three friends by collecting treasure, hiring crew, and conquering or befriending island towns.

In Islebound, you take command of a ship and crew. You sail to island towns, collecting resources, hiring crew, and commissioning buildings for your capital city. Each building has a unique ability, and your combination of buildings can greatly enhance your strength as a trader, builder, or invader. You also recruit pirates and sea monsters to conquer towns, which, once conquered, allow you to complete the town action for free, and charge a fee to opponents if they want to use it. Alternatively, you can complete events that give influence, which can be used to befriend towns.

There are many routes to success. Will you be a ruthless conqueror, careful diplomat, or shrewd merchant in your race to the top?

The player with the most wealth and most-impressive capital city will win the game!
