By sending a ship to these shipwrecks, players will collect a treasure reward.
Collecting treasure from shipwrecks also progresses the task "Treasure hunter" in the achievements, however it appears not all shipwrecks are counted towards the achievement. Treasure piles also do not count towards "Treasure hunter" .
Each Event offers more wrecks in a day, but those are not counted in the tasks Achievements.
The reward doesn't seem to be based on the capacity of the ship or the number of sailors the ship can carry but only on the number of sailors the wreck requires, which increases with the player's level.
Rewards are based on the level of the player, but seem otherwise completely random.

In addition to the materials, players will always receive experience that increases with their level.
The crew cost of salvaging a shipwreck will vary depending on the player level. If a high crew requirement becomes an issue for a player, 'La Pensee', a scouting ship with extremely high crew but very low capacity is a good choice, also worth it for exploring in general.
