Dunmast runs in your phone's browser. Put it on your home screen and it opens like an app, and it can tell you when your fleets are home.
You are playing from your home screen already.
The Port
Mills, mines, stills and powder works produce around the clock. Log in to full stores, start an upgrade, and the harbour grows a level while you sleep.
The Drydock mends wrecked command ships. The Breaker's Yard breaks what you took for parts.
Lumber Mill
Shipyard
Drydock
Breaker's YardThe Shipyard
Sloops, brigantines, frigates, galleons and men-o'-war, then found blueprints for hulls no yard draws on its own.
Light beats heavy, heavy beats medium, medium beats light. A fleet of one kind gets caught out.

LightThe Sea Chart
Pick the hulls, name the fleet and point it at a port, a wreck, a school of fish or a town. Scout first, or go in blind.
The timers are just the sailing time.
Raids
Broadsides, fireships, boarding parties and shore guns, round by round, against pirate strongholds or another captain's port. Every battle has a link. Send it.
Raid enough and the pirates come for you. A Notorious port draws a Reprisal fleet.
Cannon Battery
Harbour Chain
Fire Tower
Coastal FortressTowns
Quests from the people on the quay, a market for the catch, a smuggler who pays for what nobody else wants.
A fishing rod for the wait. Some fish have a bottle in them, and the bottle has a name in it.
Harbour Cod
Bluefin Tuna
Giant Squid
OarfishThe Delves
Caves on the Frontier, run by the captain in person with a class and a row of abilities. Bears, colliers, things with too many arms.
What comes out goes on the captain: coats, boots, a charm for the class.
Scallywag
Shieldmaiden
Norseman
WitchThe Frontier
Past the home oceans the chart keeps going: garrisons, raid captains, pirate fleets roving a tile a minute, and fights in the hundreds of hulls.
Alliances hold ports out there, build them together and raid together.
Man-o'-War
Ironclad
Marchwarden
Leviathan HunterCampaigns
The Black Flag puts a pirate captain in front of you every day, wave after wave. Bring your own fleet or join another captain's crew.
The captain's talents and gear count in every fight, at sea and underground.
Spoils
Chests, recipes, blueprints, gear for the captain: hats, rings, belts, charms. Relics that pay a bonus for good.
None of it is for sale. All of it is won.
Epic Chest
Captain's Spyglass
Officer's Baldric
Ship's BellStanding

Keepers of the old sea law. Exploration and cartography.

Master shipbuilders. Salvage and construction.

Raiders and privateers. Combat and subterfuge.

Fishermen, whalers and sea scholars. Fishing and the deep.
Membership
All of Dunmast is free to play. Members pay $5 a month for a port that builds more at once, more quests a day, bigger stores, a second daily campaign and a few hulls of their own.
Nothing in the game is bought with money except that. Everything else is earned at sea.
