In Stranded Deep, you must find a way to survive on an island without basic commodities. One of the first things you'll need to craft is a Coconut Flask. In the guide below, we go over the basic instructions on how to make one.
The first thing you need to do is gather the necessary materials. You'll need to get one Lashing and one Coconut, and both are fairly easy to find. Lashings can be crafted from four fibrous leaves (or found in shipwrecks, survivor remains, and other lone containers), and Coconuts can be found on palm trees. Once you have these, use the image below to proceed.
With the Coconut and Lashing in your inventory or on the ground near you, open your crafting menu (Press C on the PC or the right bumper on consoles) and go to the consumables tab as shown in the image above. On this menu, select the option to craft the Coconut Flask with the primary interaction button.
That's all there is to crafting a Coconut Flask! Once you have it, you can fill it with water from the Water Still.
