The DREADMOOR best boat upgrades for the documented opening demo route are the required hull-protection pieces and upgraded engine. John directs you through both before sending you toward The Throat, making them concrete progression priorities rather than a speculative endgame ranking. Storage and lighting are also developer-documented options, but the available material does not support a universal best build or a numerical comparison of every component.

Complete maintenance before spending on optional parts

Boat improvement starts before the research tree. Repair John's still to obtain the dry-dock key, restore the dock's power, bring the boat inside, clean the polyps off, and patch the damaged sections.

Those tasks establish a functioning boat and unlock the next conversations. Crafting an optional part does not substitute for an unfinished repair objective.

The demo player experience recorded by Mr. Feudal follows this maintenance-to-upgrades sequence. Use it to understand the progression order, while checking your own build's recipe quantities in the current interface.

Prioritize the quest's hull-protection pieces

After the boat is cleaned and repaired, John points you toward Chromatic Scales. Ask the merchants for the Wind-up Tin blueprint, craft the lure, catch the required Softgrazers, and process them.

Return to John to receive Scraps of Knowledge and study the hull-protection and upgraded-engine blueprints. Then craft the protection at the lathe and physically install it on the boat's armor slots.

Why prioritize it? The hull work is a required step in the documented progression, and John's dialogue ties a sturdier boat to harsher travel. That is a supported practical reason; it does not establish an exact damage-reduction percentage.

Gather more Coral Fiber or Bug Slime if the recipe is short. Research supplies the blueprint, not the finished module or unlimited crafting ingredients.

Follow with the upgraded engine and Carburetor chain

John's next engine task sends you to Gil and Bozer for a Carburetor. Their request introduces the predatory-fish lure and Harpooner catch.

Follow the sale objective carefully: the Harpooners in this chain need to be sold to the merchants, not processed like the earlier Softgrazers. Buy the Carburetor, return to the dry dock, and follow the engine-removal and installation steps.

The recorded route removes the old engine, places it in module storage, crafts the upgraded engine at the lathe, and fits the new component. Report the installation to John to finish that stage.

The player reports a noticeable speed improvement afterward. That is a demo player experience, not a measured speed test or evidence of a particular percentage increase. The engine earns its priority here because it advances the opening route and improves the documented vessel progression.

Weigh other options against the trip you are planning

The official demo announcement lists Hull Armour Mk I, two engine options, fish-storage improvement, and a roof-mounted lantern in the boat-upgrade offerings. The official Steam page also describes propulsion, hull, fuel-carrying, lighting, and burst-speed features for the broader game.

Use these as reasons to inspect your unlocked options, not as a shopping list of modules guaranteed to be craftable immediately. The developers' trawler dev diary emphasizes preparation while warning that even an improved boat does not remove the world's danger.

FAQ

What should I upgrade first in the demo?

Complete cleaning and repairs, then follow John's required hull-protection and upgraded-engine chain. Those are the supported opening progression priorities.

Does researching an upgrade install it?

No. You still need to gather materials, craft the component, and fit it to the appropriate boat slot in the dry dock.

How do I get the engine's Carburetor?

Follow John's conversation to the merchants, complete the Harpooner sale objective, and buy the Carburetor before crafting the upgraded engine.

Is there a proven highest-speed or invincible build?

The selected material supplies no complete numerical module comparison or invulnerability claim. The recommendation here is tied to the documented demo progression.
