How to Get Upgrades
Once you start repairing the ships, you will unlock the renovation table in the shipyard. Interacting with it pops up a menu to buy upgrades and unlock skills. These upgrades are for the items that you have in the game.
Buying the upgrade for the Deck Length allows you to extend its length. This will enable you to purchase larger ship licenses.

The level 2 Rag boosts the speed of cleaning surfaces, allowing you to clean more ships quickly. Tobacco Pipe level 2 gives more relaxation and increases the effectiveness of removing madness.

The goal is to optimize the mechanics to get more work done faster and save time, which will help you make more money.
Best Upgrades To Buy
Below are the five best upgrades we recommend purchasing first in Sunken Engine.
1. Garbage Bin

Garbage Bin is the best upgrade to purchase first in Sunken Engine, as it boosts the amount of garbage the bin can carry. You will be carrying the trash while repairing the ship, and having more capacity of your garbage bin allows you to carry more garbage.
This will lessen your work to clean the ship, as you will carry more garbage at a time.
2. Rag

Buy the level 2 upgrade for the Rag to enhance the speed of cleaning surfaces. You need to clean the surface of the ships when you repair them.
Cleaning them with the Rag takes much time, so purchasing this upgrade will save you time and allow you to repair the ship quickly.
3. Tobacco Pipe

This is a fun upgrade, and it allows you to relax and enhance the effectiveness of removing madness.
Your character will be frustrated while repairing the ships and selling the items at the bazaar, but having the upgrade for the Tobacco Pipe relaxes you.
4. Kitchen

You can sell pearls at the bazaar to gain more money. Although oysters give you good money, you should see pearls as a free bonus. Furthermore, the Kitchen upgrade allows you to crack open oysters.
You can go to the cracking station in the kitchen to use a hammer and point it at the oyster placed on the table, and click LMB to crack it. Hit it a few times, and you can try opening the oyster for a chance to get a pearl.
Leveling up in the game boosts the chance of finding the pearl. You have to make more sources of income in Sunken Engine to earn more money.
5. Deck Length

Unlock the Deck Length upgrade to increase its length to purchase a larger ship license. Earning the bigger ship license means you will earn more money and XP, which is crucial to level up in the game.
