Raft drinking method:
1. when holding food or water: click the left mouse button-> drink/eat.
2. You can replenish water by distilling seawater or eating baked goods (the effect is not obvious) and coconuts.
You need to eat in order to fill your stomach. You can eat potatoes, fish, shark meat and coconuts. The first three foods have little effect before cooking, which will reduce moisture, so try to put them on the cooking table before eating.
