The hull is the only thing you cannot replace mid-trip

Dreadmoor's risk model is unusually concrete: your boat carries the catch, and if the boat is destroyed, the catch goes with it. Everything else — bait, harpoons, medicine — can be replaced at a dock. The hold cannot.

That makes hull condition the single most important number on the boat, and it is a number the game does not put in a neat health bar. You read it from the state of the vessel, the noise it makes, and the visible damage.

Official material frames it as one of two things to watch: "keep an eye on the hull and fuel". That is the whole instruction, and it is enough once you understand what degrades it.

Two kinds of damage

Polyps. The contaminated water grows things. Polyps accumulate on the hull between trips and have to be scraped off at the dry dock. They are the routine maintenance job, and the demo introduces them before it lets you install anything — a deliberate ordering that says maintenance comes before improvement.

Impact damage. Creatures strike the boat, and obstacles do too. This is the damage that turns a trip into an emergency, because it happens fast and it happens when you are far from the dock.

The two interact. A hull covered in polyps is a hull you have not inspected, and a hull you have not inspected is one where impact damage goes unnoticed until it matters.

How repair actually works

Repair is a physical job at the dry dock. You bring the trawler into the slip, deal with the growth, and patch what is broken. Materials are consumed — the store description lists survival tools and repair materials as separate categories, and the demo's early chain has you collecting metal plates and rope before you have a boat worth repairing.

The dock itself has to work before any of this is possible. In the demo, the dry dock is dead on arrival and needs its own repair sequence before the slip functions. That gating is not padding: it is the game telling you that infrastructure in the Submerged Lands is always broken and always someone's problem.

Two practical rules come out of this.

Repair at every dock visit. Not every failure — every visit. The marginal cost of a patch while you are already moored is a fraction of the cost of a failure at sea.

Never leave with visible damage to save time. The trip you are rushing is the trip where the hull opens.

Upgrading the hull is a different job

Repair restores. Protection improves. They are separate steps and the game treats them separately.

The demo requires hull protection as one of two upgrades before you can attempt The Throat. The actual requirement is a crafted material made from three Softgrazers, processed into Chromatic Scales, then installed at the dry dock.

That is worth spelling out because it is the step players miss. The objective asks for a reinforced hull; the answer is a fish. Nothing in the objective text tells you to go fishing, and players who look for a crafting recipe instead of a fishing spot stall here for a long time.

The wider component list — engine, propeller, spotlight, afterburner, canister rack — is covered on the boat upgrades page. Hull protection is the one to do first, because it is the one that stops a bad encounter from becoming a lost hold.

Reading risk before you commit

The useful skill is not repairing faster, it is knowing when the boat is no longer fit for the trip you are on.

Signal What it means Action
Polyps visible but no impact damage Routine wear Repair at the next dock visit
Metal-on-metal noise, sluggish handling Hull compromised Return now, by the shortest route
Hull damaged and night approaching Two risks stacking Sleep or dock; do not push out
Hold full and hull damaged Maximum exposure Dump low-value fish to save weight, go home
Creature actively striking the boat Immediate danger Manoeuvre away, do not fight back

The fourth row is the one players resist. Dumping fish feels like throwing away profit, but a lighter boat is faster, and a full hold on a damaged hull is the exact situation the game punishes hardest.

Why this matters more in Early Access

The studio has said the trawler's progression is one of the things it intends to rebalance during Early Access: "from the balance of the economy and the progression of your trawler to the risks of nighttime expeditions". That means costs, durability and repair requirements may all move.

What is unlikely to change is the rule underneath: a destroyed boat loses the catch. That single sentence shapes every decision in the boat silo, and it is the one thing worth building habits around now.

If you want the full picture of what the boat can become, read the upgrades page. If you want to know when the water gets worse, read night survival. And if you are still in the first hour and none of this is available yet, the beginner guide covers the order the demo expects.
