I think it would be cool to have ships be able to make offline revenue in another way that is not Trade fleets. And the solution would be voyages.
There would be multiple types of voyages that yield different rewards and require different ships (this would make a use for Fluyts or Galleons)
Something like "Chart an Unexplored Island - Looking for Sloops and Galleons" It would take 8-16 hours depending on how good the ships you send are, meaning the better the ships you send, the more time it will take (but better rewards too ) so for this example, The Voyage wants sloops and Galleons, so a fleet full of level 10 sloops and galleons will get you the most rewards. Rewards will come in the form of gc and cargo
REWARD TABLE
no wanted ships, all less than level 10 - 3k gc no chance at cargo
no wanted ships, 4 less than level 10 - 5k gc no chance at cargo
no wanted ships, 3 less than level 10 - 8k gc no chance at cargo
no wanted ships, 2 less than level 10 - 8k gc no chance at cargo
no wanted ships, 1 less than level 10 - 10k gc no chance at cargo
no wanted ships, all level 10 or up - 18k gc no chance at cargo
1 wanted ship - gc TBD - medium chance at cargo
2 wanted ships - gc TBD - better chance at cargo
3 wanted ships - gc TBD- 100% cargo
4 wanted ships - gc TBD 100% cargo
5 wanted ships - gc TBD 100% cargo
I still need time to work out a lot of the gc values so post below what fair amounts of gc for voyages would be
Cargo would be different for each voyage, so
(side note, only two ships would be "wanted for a voyage so it would be random between the listed ones)
"explore uncharted island" = Wood | Ships wanted: Fluyt, Brig, Howker, Cutter
"salvage a sunken ship" = iron | Ships wanted: Merchantman, Trade Galleon, Sloop, Large Fluyt
"meet a famous blacksmith" = tools | Ships wanted: Sloop, Cutter
"raid a plantation" = cotton | Ships wanted: Sloop of war, Brigantine, War galleon, Merchantman
"go on a hunting trip" = food | Ships wanted: Galleon, Large Fluyt, Frigate, Cutter
"party at a tavern till you drop" = rum | Ships wanted: Sloop, Trade Galleon, Galleon, Howker
"destroy a merchant convoy"" = tobacco | Ships wanted: Large Frigate, Sloop of war, Brig of war, Flag galleon
"Fight and plunder a notorious pirate" = gold bars (you get no cargo from this specific voyage unless you have 5 wanted ships in your fleet, and if you have 5 wanted ships, each ship gets 10 gold bars) | Ships wanted: SoL, Frigate, Large Frigate, Sloop of War, MoW, Flag Galleon
Cargo from voyages would only be stored on ships that are wanted for the voyage, so if the voyage wants sloops and your fleet only has 3 sloops, those sloops are the only ships that will get cargo from the voyage. Looking at the table for the wanted ships, there are no levels... this is because the level of the wanted ship determines how much cargo you get.
level 1-4, 35% of total ships cargo
levels 5-9, 55% of total cargo
level 10, 90% of total cargo
level 11, full cargo
I think this would be a good way to make money and cargo without having to set up a trade fleet. There would be consequences to this of course, you can't be a pirate and expect everything to go great!!
Here are some events that could happen instead of you completing the voyage
explore an uncharted island - "your explorers went to the wrong island!" gain nothing, lose nothing, "your explorers were met by a hostile tribe" gain nothing, lose 5 crew on each ship of the voyage, "your explorers narrowly escaped an enemy fleet" keep all cargo and gc from voyage, fleet gains 10 danger
salvage a sunken ship - "another crew got here before you" Gain nothing, lose nothing "A kraken was living inside the ship and attacked your fleet!" gain nothing, all ships on voyage lose 5 crew and take 50% damage" "A storm struck your fleet" keep all cargo and gc, each ship takes 25% damage
meet a famous blacksmith - "the blacksmith was not interested in meeting with you" gain nothing lose nothing "The blacksmith was dead when you arrived!" keep cargo form voyage but don't get any gc
raid a plantation - "The plantation was heavily guarded, so your crew didn't attack" gain nothing lose nothing "the plantation was heavily guarded but you attacked anyways" each ship goes down to 15 crew, but you keep all cargo and gc you would normally get "The plantation was abandoned" only gain half the cargo and gc you would normally get "the plantation had ships protecting it" All ships take 15% damage, and the last ship in your fleet either loses a level, or sinks, no cargo or gc gained
Party at a tavern - "you got so drunk you forgot about the mission" gain nothing lose nothing "the rum you got wasn't even fit for a dog to drink" keep gc lose all cargo
Go on a hunting trip - "The butcher didn't want your meat" keep cargo, lose gc "the crew was lazy and didn't hunt" gain nothing lose nothing "the animals fought back!" each ship loses 5 crew keep gc keep half of the cargo
destroy a merchant convoy - "Our intel was off! This fleet didn't have the cargo we wanted" lose the gc, but get half the wood instead of tobacco "we made peace with this convoy and let them be" gain nothing lose nothing "we made peace with the convoy so they shared some cargo" get half cargo, half gc
fight a notorious pirate - "This pirate was stronger than I expected" Gain nothing, tail ship loses 1 level or sinks "this fleet was a decoy! the real fleet got away" gain nothing, lose nothing "The pirate's flagship was loaded with gunpowder and we hit a sweet spot" Gain extra gc, but lose cargo and each ship take 10% damage
This took long to think of and write so let me know if I should change anything or add anything
