Net A Fish Boats: Hulls, Upgrades and Catch Rates

The hull determines your maximum catch rarity and the available levels for Trawl Net, Engine and Sonar. Choose your next hull around the rarity you want to catch or the component cap you need to raise.

The early progression runs Rowboat → Motor Skiff → Trawler → Catamaran → Ironclad. Abyss Leviathan is hull stage 8, followed by Sunforged Dreadnought at stage 9. Hull stage and component level are separate: a stage-4 Catamaran allows the three main components to reach level 8.

A higher rarity limit makes a hull useful even before you finish its component upgrades. For more fish per minute, budget for those upgrades too. If a Rebirth requirement blocks your next purchase, use the Rebirth guide to plan that milestone.

1. Reach Rebirth 1 and save $25,000.
2. Go to Boat Dock and press E at the boat interaction to open the Boat menu.
3. Buy the Rowboat. Its component buttons become available once you own the boat.
4. Let it trawl automatically while you continue fishing or doing other activities. The boat circles near your dock, shows a return countdown and unloads each haul into Fish Cooler.
5. Reopen the Boat menu to check the catch-rarity limit, fish per trip, trip interval, luck and cumulative catches.

With all three main components at level 0, the Rowboat starts at 2 fish per trip, a 70-second interval and ×1 luck, with an Epic rarity cap. You can improve it immediately or save toward the $500,000 Motor Skiff, which opens Legendary catches and level-4 components.

Open the Fish Cooler to manage the fish your boat brings back. For combining the boat with your other automatic fishing equipment, see the online AFK setup.

Choose an upgrade for your goal

• Trawl Net: Increase the number of fish brought back per trip. Prioritize it when each haul is small, especially if you have upgraded Engine while leaving the net behind.
• Engine: Shorten the interval between trips. It improves how often you receive the entire haul, so its value grows alongside your Trawl Net.
• Sonar: Improve rare-fish luck. Choose it when catch quality matters more than raw fish count; the hull still sets the normal catch-rarity limit.
• Cold Storage: Increase the size of boat-caught fish by 4% per purchased level. Scroll down in the Boat menu to find it. Rebirth 5 opens the first level, and each subsequent Rebirth opens one more purchasable level, up to level 10. For example, after buying level 1, level 2 requires Rebirth 6.
• Lucky Figurehead: Add 2 percentage points per purchased level to the chance of receiving an extra fish one rarity tier higher. Its first level opens at Rebirth 10; each subsequent Rebirth opens another purchasable level, up to level 10.

For an early catch-volume purchase, Trawl Net level 0 → 1 costs $3,000 and raises the haul from 2 to 3 fish. Engine level 0 → 1 costs $3,600 and shortens the interval from 70 to 66 seconds. The net gives the larger immediate volume increase in that starting configuration. Sonar’s first level costs $4,500 and raises luck from ×1 to ×1.25 instead.

What NEXT HULL means

The three main components each have an overall level limit of 34, but your current hull limits how far you can upgrade them now. NEXT HULL means that individual component is at the current hull’s cap.

1. Check the next hull’s cash price and Rebirth requirement in the Boat menu.
2. Meet those requirements and purchase the hull upgrade.
3. Return to the component rows and buy the newly opened levels.

Changing hulls does not fill the new levels automatically. Other components that remain below your current hull’s cap can still be upgraded. Cold Storage and Lucky Figurehead follow their own Rebirth-based level requirements.

Component upgrades also change the boat’s appearance: Trawl Net adds a winch and buoy line at level 1, a third buoy at level 4 and a fourth at level 7. Engine adds a foam wake at level 1, exhaust smoke at level 4 and speed trails at level 8. Sonar adds an antenna at level 1 and sonar pulses at level 4.

Upgrading from Trawler to Catamaran costs $300 billion and requires Rebirth 7. It raises the catch-rarity limit from Apex to Monarch and opens component levels 7–8. With all three components still at level 6, the Catamaran keeps the same haul, interval and luck as the previous Trawler setup.

Use fish per minute = fish per trip × 60 ÷ trip interval in seconds to compare configurations. Take both inputs from the same setup. The rates below are calculated from the listed haul and interval; compare luck and rarity separately.

The Motor Skiff comparison shows why Engine and Sonar cannot replace Trawl Net upgrades: the interval and luck are identical, but upgrading the net from level 0 to 4 triples the haul.

For Catamaran, buy the hull first when Monarch access is your goal. For a substantial catch-volume improvement, also fund the component levels: reaching level 8 raises the listed rate from 10 to about 14.6 fish per minute. The first steps from level 6 are:

• Trawl Net, $3B: 8 → 9 fish per trip.
• Engine, $3.6B: 48 → 44 seconds per trip.
• Sonar, $4.5B: ×2.5 → ×2.75 luck.

For raw volume at that starting point, Trawl Net offers the stronger first purchase: a larger haul increase at a lower price. Choose Sonar first if rare-fish luck is your priority.

Abyss Leviathan configuration example

An Abyss Leviathan setup with all three main components at level 16 has panel values of 31.5 fish per trip, 22 seconds and ×5 luck, with an Empyrean rarity cap. Those values calculate to about 85.9 fish per minute. Use this as a configuration example, including its active bonuses, rather than a base rate that comes with buying the hull.

Ship Shape, in the Skill Tree’s Crew & Dock branch, increases boat trip speed. Its successive bonuses are 2%, 4%, 6%, 8% and 10%, with each upgrade costing 1 skill point. These are the successive total bonuses: moving from 2% to 8% takes three more points. If the button reads REBIRTH FOR POINTS, you need more skill points before buying another level. See the Skill Tree guide for the branch progression and broader builds.

Two helper game passes also affect boats:

• Turbo Helpers: Makes Boat, Fisherman and Spear Gun work 50% faster and bring back double the fish. It targets catch volume across those helpers.
• Helpers Luck: Gives Boat, Fisherman and Spear Gun ×2 luck. Choose it for rarer catches rather than a larger stated haul.

When comparing a boosted boat, use its current haul and interval values. Keep bonuses already included in those values in the calculation once; do not multiply them in again. A “50% faster” benefit also does not mean a trip takes half as long.
