Surviving the endless ocean in 100 Days at Sea demands a sturdy vessel. While a basic wooden raft serves you in the early days, knowing how to get metal raft in 100 days at sea is essential for tackling dangerous zones like the Ice Region and Rival Rigs. This guide explains how to get metal raft in 100 days at sea by breaking down the necessary materials, workstation upgrades, and strategic steps based on player experiences and community reports. Unlike official recipes, many of these details come from repeated testing by the game’s dedicated community, so use this as a reliable roadmap for your upgrade journey.

Why Upgrade to a Metal Raft?

Your starting wooden raft will crumble under the pressure of late-game threats. Here’s why the metal upgrade makes a difference:

  • Increased durability – Metal hulls withstand hits from sharks, cannon fire, and environmental hazards.
  • Damage reduction – Enemies deal less damage to metal structures.
  • Exploration access – Some areas like the Ice Region and Rival Rigs are nearly impossible to survive with only wood.
  • More storage – Metal rafts allow larger deck expansions and extra chests.

The official 100 Days at Sea FAQ notes that raft building is confirmed, but exact build steps and material counts are not yet listed because they require gameplay screenshots. That means much of what we know about the metal raft is the result of community experience. Players have consistently reported that surviving past Day 50 without a metal raft becomes extremely difficult.

The table below summarizes how the metal raft compares to earlier tiers.

Players aiming for the Ice Region or Rival Rigs should set the metal raft as a priority. According to community reports, even a fully reinforced wooden raft can break apart in a single encounter with a Fire Golem or during a raid.

Materials You’ll Need for a Metal Raft

The exact recipe for the metal raft is still unverified officially. The FAQ advises treating recipe names, material counts, and workstation rules as tentative until in‑game UI confirms them. However, the following list is based on repeated player experience and reported by multiple sources in the game’s community.

MaterialEstimated QuantityCommon Sources
Iron Ore60–80Mining islands (breakable rocks)
Coal30–40Mining islands, loot crates
Scrap Metal40–50Shipwrecks, Rival Rigs, floating debris
Wood Planks20 (for smelting fuel)Chopping trees, crafting from logs
Nails30–40Crafted from Iron Ingots at Workbench
Stone10Shorelines, mining islands

Note: Quantities vary based on raft size. Smaller solo rafts may use fewer ingots.

“How do I collect iron ore efficiently?” – Use a pickaxe (crafted from wood and stone) and head to small rocky islands. Smelt the ore in a furnace to produce iron ingots. One ingot typically requires 2 ore + 1 coal.

If you are looking for an efficient resource loop, prioritize the harpoon. The FAQ emphasizes using the harpoon/resource flow to gather materials quickly. Many players set up a “resource station” where they farm logs, ore, and scrap in the first 20 days.

Step-by-Step Crafting Process

Before you can build the metal raft, you need to set up the right workstations. The progression follows the survival priorities outlined in the FAQ: resources first, raft base second, defenses and weapons third. This means you should have a solid wooden raft, basic weapons, and armor before investing heavily into metal.

1. Build a Furnace

MaterialQuantity
Stone1
Wood5

The furnace lets you smelt iron ore into ingots. Place it on your raft.

2. Smelt Iron Ingots

Fuel the furnace with wood or coal. Wait for the smelting animation. One furnace load can produce 4–5 ingots at a time if you keep it running.

3. Craft a Metal Workbench

MaterialQuantity
Iron Ingot5
Scrap Metal3

The Metal Workbench is required to craft metal raft components. Without it, you cannot shape the ingots into usable parts.

4. Build Metal Raft Parts

Using the Metal Workbench, craft the following (community estimates):

ComponentIron IngotsScrapNails
Metal Foundation855
Metal Wall633
Metal Railing422
Metal Door311

You will need to replace your entire wooden hull or add metal sections. Many players build a metal floor first, then gradually upgrade walls and rails.

Expert tip: Do not dismantle your entire wooden raft at once. Keep a core wooden section afloat while you construct the metal frame beside it. This prevents your whole base from collapsing if something goes wrong.

Common Mistakes to Avoid

Based on community experience, here are the biggest pitfalls when attempting to get a metal raft in 100 Days at Sea:

  • Rushing metal without a secure food/water supply. The FAQ warns that the first 10 days should be treated as a survival setup window. Focus on basic needs before investing time in smelting.
  • Forgetting about the Advanced Forge. Some players report that an Advanced Forge (10 iron ingots, 5 scrap) is needed to unlock certain metal raft upgrades. Check your workstation menu to see if you need one.
  • Neglecting defenses. A metal raft only helps if you survive the journey to build it. Craft weapons and armor first. The FAQ recommends defenses and weapons as a third priority after resources and raft base.
  • Overcommitting resources too early. Save a backup set of tools and materials in a chest before you start upgrading. If your raft sinks during construction, you won’t have to start from scratch.

Metal Raft Maintenance and Expansion

Once you have your metal raft, you will need to maintain it. Unlike wood, metal does not catch fire as easily, but it can still be damaged by explosive attacks. Keep a repair hammer and spare metal parts on hand.

Suggested Expansion Order

  1. Replace the floor planks with metal foundations.
  2. Build metal walls around your bed and chests.
  3. Add metal railings to prevent being knocked off.
  4. Install a metal door for extra protection during raids.

Some endgame players also add a second floor or a crow’s nest using metal supports. These advanced builds are still being tested by the community.

FAQ

How to get metal raft in 100 days at sea quickly?

Focus on mining iron ore and scrap during the first 20 days. Build a furnace immediately after you have a stable food supply. Smelt ore whenever you have coal. Many players skip unnecessary crafting and dedicate a full session to resource gathering. According to community reports, you can finish a metal raft by Day 25 if you work efficiently.

Is the metal raft necessary to finish the game?

Yes, for most players attempting to complete the “Day 100” badge and explore endgame areas. The FAQ notes that bosses like Fire Golems, Lord of Lava, and raids require stronger equipment. A metal raft gives you the durability to retreat and reposition during fights. Solo players especially benefit from the extra protection.

Can I upgrade to metal raft without a furnace?

No. A furnace is required to smelt iron ore. You must also build the Metal Workbench to craft the parts. Skip the furnace only if you find already‑smithed ingots in loot, but those are very rare. The FAQ reports that community gameplay checks are still needed to confirm loot tables.

Where can I find more verified information?

Final Thoughts

Learning how to get metal raft in 100 days at sea is a milestone that opens up the full game. While the official recipe list is still pending, the community has pieced together a reliable path through repeated testing. Stick to the resource priorities from the FAQ, set up your workstations in order, and gradually replace your wood with metal. Your raft will become a fortress capable of weathering any storm – and any raid.
