-The Shark is set to attack the raft every 5 minutes, but should you enter the water, the five-minute timer will be paused until you exit.
While it's entirely up to you, having space in-between your collection nets is completely fine. Not only does it save you resources, but the actual chance of items slipping between the gap is very unlikely.
While you may want to explore the islands straight away, we recommend waiting until you've at least crafted an axe and have the ability and means to reach the higher points of the island. One of the only reasons you will want to visit an island early on in the game is to search the shallows along the beach for resources.

-When leaving your raft, always use an anchor, even if it's just for a short period. Not only is it easy to lose track of your Raft should it get swept away by the current, but being left stranded with a circling shark hot on your tail, you'll quickly learn just how vital an anchor can be.

Bonus tip
When moving around your raft, especially when picking up debris and rubbish, it's surprisingly easy to fall into the water. When you're first starting out, falling into the water can be one of the worst possible situations, as your chance of death is significantly higher. Not only will you lack many of the necessary weapons and skills to survive a Shark attack, but there's a good chance you'll also be fatigued due to a lack of water and food consumption. If this is the case, you'll want to get back onto your raft as quickly as possible; otherwise, you'll become shark food.
