Dredge: Research Trees and Secret Cargo Hold Locations

The recent release of Dredge has been met with mostly positive responses. Players become fishermen and navigate a dangerous ocean while catching creatures deep underneath. You will also have several mysteries and puzzles to solve alongside ‘Research Trees.’

These will be helpful as you progress into the game to improve your understanding of how to battle adversity and win rewards. In that regard, the following guide will help players know about the Research trees in Dredge and how to navigate them. 

Dredge: What are the Research trees, and what they do

The Research trees will have specific research costs and objects that can be researched with their stats. Players must purchase the stuff they research, which should be easy. 

Research tree: Nets

A lot of fish can be caught through nets, which in turn means a great deal of side income for players.

Research tree: Rods

The ship’s base value is 50% of the fishing speed, with the fishing speed of the rods being added. The tree in the top right corner (lines with no bottom and Fathomless Winch) will get unlocked after you get the Sampling Device from the Researcher.

Research tree: Pots

Players will rely on pots to capture crabs, but there are some more benefits to them. You will be able to use them parallelly to mark clearly, the pathways between rocks at night. You can also keep them as markers at various places that you think are important since pots are visible on the map.

Research tree: Engines

The essential speed of your ship is 10kn, so any more engines will only increase your speed. You want to keep an eye on the number of slots your updates will take up. The Peculiar Engine has a total speed of 14kn through two slots, meaning there is 7kn for each slot.

Here is the complete list of engines and how much speed they provide for each slot.

  • Peculiar Engine: 7kn each slot
  • Rusty Outboard Engine: 5kn each slot
  • Weak Valve Engine: 6kn each slot
  • Improved Outboard Engine: 7.5kn each slot
  • Refined Outboard Engine: 8.3kn each slot
  • Twin Prop Engine: 8.75kn each slot
  • Jet Drive Engine: 9kn each slot
  • Twin Jet Drive Engine: 10kn each slot
  • Engine Stack: 10.6kn each slot

While it may look like the best engine is the last one, players can also try out some of the middle-ground engines for the other slots as they will give your variety and protect you from a total malfunctioning of the same engine across every slot.

Dredge: What items to buy and the location of the secret storage

Players should get a great rod in the beginning as you go from Great Marrow and go left to the lighthouse. You will come across a shrine and will listen to devious tunes. Bring 5 cods here.

After you fit them in, the deep ones will give you the Sinew Spindle fishing rod. It is helpful in shallow waters and provides more income right from the start.

Players have to start early on in the morning as it is a whole day’s journey for the engine to find and, eventually, the secret hold. The island is in 5L, so go right from Greater Marrow with your focus being between the rocks and two islands only.

You will encounter a shipwreck with its cargo hold containing a Weak Valve Engine and a fishing rod. Do not fit in the engine instantly as it will delay your journey, so keep it in your storage by clicking the mouse’s middle button. Once you have found all the objects present, do make sure to keep something behind.

This is the only way to ensure you can return to this storage hold in the future. Otherwise, it will seal off permanently, and the 12 slots will no longer be accessible. After you are done, go back to the marrow, and players should be home by late evening to avoid dangerous monsters. 

Thus, that is all the information players will need regarding the Research trees, along with the secret hold and found the fishing rod early on. All of it will be helpful as you move deeper into the game, with the early searches being worthwhile.
