Crystal Sail

You were surveying a planet when a malfunction caused your ship to crash. Everyone on the ship is gone and you are the only one left. You have no knowledge of spaceship design, but you can build beacons to send emergency signals. 

As a hobby you made toy sailing boats and this information with help survival and explore on this ocean planet.

Sail across the sea using crafted ships to find crystals and construct five signal beacons for rescue.
