⚠️ Alpha: not fully tested yet. The boats are brand new (real ships that find their own way over the water) and the mod has not been played through in a long game yet. Expect rough edges, try it on a copy of your save first, and please tell me in the comments what goes wrong.

🎣 Fishing Fleet

Fishing Fleet

Fishing harbours on your coast, from a fisherman rowing out in his boat to a factory port with two stern trawlers. The boats are real ships: they sail out, fill their holds at the fishing grounds and bring the catch home, and you can click them like vehicles.

A fishing harbour in five levels, from 1 rowboat with a hold of 20 fish to 2 stern trawlers with 500 fish each, fish stocks in the sea that grow back when you leave them alone, and three new fish foods plus fish meal for your animal feed.

Five harbours, one spot

βš“ The harbours

  • 🚣 I Β· Fishing jetty: a wooden jetty and a fisherman's hut. The fisherman rows out, casts his rod and rows back. No fuel, 2 workers
  • πŸ›₯️ II Β· Fishing hut: a net shed and a motor boat with rods and long lines, reaching 70 tiles out to sea
  • 🚒 III Β· Cutter harbour: a quay, a fish hall and an ice machine; 2 beam trawlers drag their trawls on both sides
  • πŸ›³οΈ IV Β· Trawler harbour: a cold store and a quay crane; 2 side trawlers haul their nets with gallows and a net drum
  • 🏭 V Β· Factory trawler port: a refrigerated warehouse and gantry cranes; 2 stern trawlers haul their nets up the stern ramp, reaching 220 tiles out
  • ⬆️ Upgrade in place: every level grows wider on the same spot
  • β›½ What they need: workers, diesel for the motor boats (pipe port F), power for the ice machine and cold store, and maintenance from level II on

Five boats

🌊 Out at sea

  • πŸ–±οΈ Click a boat like a vehicle: what it is doing (and why it waits), the fish in its hold, the diesel in its tank, how far out its fishing ground is, a button for its harbour and one to follow it with the camera
  • 🧭 They find their own way over open water, around coasts, islands, piers and anything standing in the water; only one boat manoeuvres in the harbour at a time, the other waits off the harbour
  • 🐟 They earn the fish: a boat sets out only for a ground with a full hold of fish and takes its catch from the sea there
  • βš“ Landing: back in its berth, the harbour unloads the catch at port X and refuels the boat with diesel from port F
  • 🎬 All animated: the fisherman rows, the boats drift or tow their trawls, booms come down, net drums turn, the crane and the gantry lift the net with the catch
  • 🌱 Fish stocks that regrow: fish the grounds hard and they run low, leave them alone and they grow back
  • πŸ—ΊοΈ Bigger boats go farther: each level reaches farther out to fresh grounds
  • πŸ“‹ Fishing grounds and Boats panels in the harbour window: the fish within reach and what every boat is doing
  • πŸ•ŠοΈ Seagulls follow the boats, closest when they haul or bring the catch home

From the sea to the table

🍽️ Fish foods

  • πŸ”ͺ Fish processing plant: 24 fish + water β†’ 16 fish fillets + 8 fish meal
  • πŸ”₯ Smokehouse: fillets + wood β†’ smoked fish
  • πŸ₯« Canned fish in the vanilla food processor: fillets + water + salt
  • πŸ„ Fish meal β†’ animal feed in the mixer, for your chickens or the farms of Livestock Farming
  • 🍣 Three new protein foods for your settlements: fish fillet, smoked fish and canned fish

How to start

  1. Research Fishing (after Basic farming) for the fishing jetty, the fish processing plant and fish fillets.
  2. Place the fishing jetty from the Food toolbar on the coast: the buildings on land and the berth (the dark blue tiles) in open water; the coastline can run anywhere under the quay in between. Keep the sea in front of it open.
  3. Take the fish off port X to the fish processing plant and the fillets to your settlements.
  4. Motor fishing boats (after Basic diesel), Fishing cutters (after Cargo depot), Trawlers (after Cargo depot III) and Factory trawlers (after Cargo depot IV) unlock levels II to V, the smokehouse and canned fish.

Good to know

  • 🌍 Speaks all 21 languages of the game.
  • πŸ–οΈ Fits real coasts: of the 34 tiles from land to sea, the first 8 need land, the last 8 open water, and the 18 in between can be either.
  • Leave room on both sides of a harbour if you want to upgrade it later: the levels are 4, 6, 10, 14 and 16 tiles wide.
  • Harbours close to each other share the same fishing grounds.
  • Upgrading a harbour gives it the new level's boats; what the old boats carried is lost.
  • Can be added to existing saves, but not removed once you have built its buildings or products.
  • Made for Captain of Industry 0.8.7.

* The boats ride the game's waves: they rise and fall with the sea and pitch and roll with it, so they no longer sink into big waves (small boats follow every wave, big trawlers only the long swell)
* The boats keep clear of the game's own ships (the main ship, cargo ships): they plan their way round them, find a new way when one comes into it, steer round a ship that lies still and stop for one under way
