100 Days at Sea: How to Drop Items

Surviving the unforgiving ocean in the Roblox hit 100 Days at Sea requires quick reflexes, strategic planning, and flawless resource management. As you navigate the mysterious waters of the Bermuda Triangle, your inventory will quickly fill up with driftwood, scrap metal, and wild island materials. Knowing 100 days at sea how to drop items is essential to prevent your inventory from clogging, allowing you to prioritize high-value resources like iron, platinum, and rare companion chests.

Managing your inventory revolves around two main systems: your hotbar (which holds active tools and weapons) and your storage sack (which holds bulk materials gathered from the sea). Dropping items from these two systems requires different controls.

Dropping Items from Your Sack

The sack is your primary storage unit for raw resources. When you use your Harpoon to hook floating boxes or pick up materials on islands, they automatically go into your equipped sack.

To drop these items back onto your raft or the ground, follow this method:

  1. Press the corresponding number key on your keyboard to equip your Sack from your hotbar.
  2. Press the F key on your PC keyboard. If you are playing on mobile, tap the Unstore or Drop button that appears on your screen.
  3. The sack operates on a Last In, First Out (LIFO) system. This means pressing the drop key will discard the very last item you picked up.
  4. Continue pressing the key to drop items sequentially until your sack is empty.

Discarding Tools and Weapons from Your Hotbar

If you need to free up hotbar space or share a weapon with a crewmate, you can drop active tools directly:

  1. Press the hotbar slot number to equip the tool or weapon you wish to drop.
  2. Press the Backspace key on your keyboard.
  3. The item will drop directly in front of your character, allowing you or another player to pick it up.

Instead of dropping items onto the floor of your raft, stand directly next to your Grinder or Campfire. Pressing the drop key while facing these stations will automatically deposit the materials directly into them, saving you valuable time.

Sack Upgrades and Class Buffs

When you first begin your journey, your default starter sack has very limited capacity. Hoarding low-tier resources like basic wood planks will quickly max out your slots, forcing you to constantly drop items to make room for rare ores. To avoid this bottleneck, you should prioritize upgrading your sack as early as possible.

Upgrading your inventory capacity is tied to two main progression mechanics: unlocking specialized Classes using Pearls and purchasing physical upgrades from the Traveling Merchant.

Inventory-Focused Classes

Unlocking specific classes grants permanent passive buffs and equips you with superior starting gear at the beginning of each run.

Camper2 Stars70 PearlsGood Sack (+10 Slots)+10% Max Health
Adventurer3 Stars250 PearlsGiant Sack (+15 Slots)+15% Max Health, Less Hunger

The Traveling Merchant

If you do not have enough Pearls to unlock high-tier classes, keep an eye out for the Traveling Merchant who periodically visits your raft base. They sell the Good Sack and Giant Sack directly for Doubloons, allowing you to upgrade your inventory mid-run.

Starter Sack

  • 5 Inventory Slots
  • Default starting bag
  • Fills up within minutes of harpooning

Good Sack

  • 10 Inventory Slots
  • Unlocked via Camper Class
  • Great for early-to-mid game stability

Giant Sack

  • 15 Inventory Slots
  • Unlocked via Adventurer Class
  • Essential for late-game island exploration
Losing Your Gear

Be careful when dropping high-tier weapons like the Flintlock or Machete. If you drop them directly into deep water, they may sink and despawn, costing you valuable resources to craft them again.

Step-by-Step Inventory Management

Keeping your raft organized is the secret to reaching Day 100. A cluttered raft floor makes night-time raids from Ghost Pirates and sharks incredibly difficult to manage. Follow this step-by-step strategy to optimize your inventory flow.

1

Filter Your Harpoon Grabs

Do not blindly reel in every piece of debris you see. Target high-value floating crates and plastic barrels first. If your sack is nearly full, ignore single wood planks and prioritize metal scrap.

2

Process Raw Materials Immediately

As soon as you return to your raft, walk to your processing line. Unstore your gathered wood and scrap metal directly into your Sawmill and Grinder. Processing raw materials immediately keeps your sack empty and ready for your next island trip.

3

Utilize Organized Chest Storage

Craft several wooden storage chests and place them in a designated crafting area. Group your items by type: keep one chest for building materials (wood, stone), one for crafting components (gears, scrap), and one for food and medicine.

Build a Recycler structure on your raft. If you have excess low-tier items or old tools that you no longer need, drop them into the Recycler to convert them back into valuable Doubloons.

Chests and Crafting Integration

Your crafting workbench automatically detects resources stored in chests on your raft, provided they are placed within a close radius. You do not need to manually unstore items from your chests to craft new defenses!

Automating Resources with Companions

If you find manual looting and dropping tedious, you can automate these processes by equipping Companions. Companions are helpful allies obtained by purchasing specialized chests from the game's shop using Pearls. Several companions possess unique buffs that directly assist with resource collection and inventory management.

CompanionChest SourcePearl CostDrop RateInventory Utility Buff
OctopusWarrior Chest80 Pearls16%Automatically brings nearby materials every 120 seconds

CrowMagma Chest120 Pearls30%Searches surroundings and brings food every 120 seconds
SeagullPirate Chest120 Pearls30%Brings food items to prevent starvation during long voyages

By utilizing these companions, you can focus on building defenses and exploring islands while your pets handle the tedious task of gathering and organizing dropped loot.

Daily Survival Checklist:

  • Verify tool durability before leaving your raft base [1.1.1]
  • Empty your storage sack completely before docking at a new island
  • Smelt raw ores into ingots to maximize chest space
  • Equip a resource-gathering companion like the Octopus or Salamander
Companion Stacking

While you can own multiple companions, you can only have one active companion equipped at a time. Choose a gathering pet during the day and switch to a combat pet like the Shark or Magma Golem before nightfall.
