Prehistoric Farm Boats: How to Upgrade Your Boat and Reach New Fossil Islands

Upgrading your boat access in Prehistoric Farm comes down to two verified stages. Your first boat needs no purchase — in a recorded first session, the player simply took a boat from the spawn area and reached a dig island in under a minute. The next step up is a bigger boat bought for 4,000 coins at the home island, which is your entry into sailing to new fossil islands. Beyond that purchase, boat names, higher-tier prices and island-by-boat unlock lists aren't documented yet — this guide sticks to what the sources actually show, so you can act on it today.

How boat progression works

Boats in Prehistoric Farm are player-owned vessels. They sit at docks, and you re-launch your own boat from a dock whenever you want to hop between islands — the recorded player spotted his at a dig island dock ("I think this is my boat right here"), relaunched it, and set course for the next island.

The upgrade price is the only purchase requirement mentioned in the recorded session; other requirements are not established. The game's official description lists "Buy bigger boats and sail to new fossil islands" as the first Explore action, confirming two things: boats are acquired by purchase, and more than one size exists. In the narrated session, the only gate on the upgrade was the coin price — no quest, no code item, no level requirement.

Here are the two stages the sources verify:

The starter boat: water travel from your first minutes

You don't unlock your first boat — you already have access to one. In the player's brief pre-recording session, all he did was "take a boat from the spawn area over to here, which is like it took me less than a minute." That establishes the starter boat's baseline job: the quick hop from spawn to a nearby dig island.

It also handles repeat round trips. After digging on an island, the player returned to the dock, relaunched the same boat, and sailed on toward Triassic Island and then Jurassic Island. Later, when he needed a better shovel, the same routine brought him back toward spawn. So the first boat already covers the inter-island loop a new player needs — it's just that its owner describes it as "extremely slow," which is exactly what pushes you toward the upgrade.

The next boat: 4,000 coins at the home island

The upgrade route shown in the recorded session:

1. Sail back to the home island. Your starter boat handles the return leg fine.
2. Check the next boat's price. It was quoted at 4,000 coins. The recorded session shows the price check happening at the home island; it doesn't capture the exact shop or kiosk interaction, so expect to find the boat offer when you look around there.
3. Close the coin gap by digging and selling fossils. The player had 3,600 of the 4,000 and planned to sell some of his fossils to make up the difference. Digging basics are covered in our Prehistoric Farm how to play guide, and dig spots live on the dig sites page.
4. Check the purchase offer once your coins cover the observed price. The session did not complete that boat purchase, so its full interaction is not demonstrated.

Two budgeting notes. First, coins have to stretch: in the same session the next shovel upgrade cost 12,000 coins, so plan your spending between boat and shovel priorities. Second, these prices come from a single recorded playthrough — it's worth rechecking the boat lineup and prices after economy or map updates on the Updates page.

What bigger boats unlock

The payoff of upgrading is stated consistently across three sources, including the game's own description: bigger boats open access to new fossil islands. That's the verified unlock wording — no source names which specific islands a specific boat size reaches, so treat any per-tier island list you see elsewhere as unverified.

The official Explore list frames the rest of the sea loop around the same boat-and-island travel: fishing the open sea and diving for rare catches, sneaking into the Sunken Grotto to steal sea reptile eggs, and teaming up to take down the giant Mosasaurus with spears. Those activities sit in the same exploration loop as your boat, but no source states that any of them requires one particular boat size — don't assume you must own a given boat before trying them. Start planning routes on our fossil islands and open sea pages, or see fishing, diving, the Sunken Grotto and the Mosasaurus guides for each activity.

Getting on the water while you save

If your boat still feels small or the 4,000 coins aren't together yet, there's a documented stopgap: an aquatic dinosaur. As one guide puts it, "if your boat is small or not ready, a sea dino that replaces it puts you on the water without the usual wait." Its duration is undocumented, so treat it as an alternative ride — nothing documents whether a sea dino matches a bigger boat's travel range, so it's a way onto the water, not proven equal access to the far islands.

Choosing when to upgrade

Upgrade when the starter boat's range stops matching your goals: if the trips out to Triassic Island and Jurassic Island already feel long, or the fossil sets you need come from islands beyond your current reach, head to the home island, check the boat price, and sell spare fossils until you can buy. If you're still filling your early period sets, the starter boat's nearby dig loop is enough to keep earning — pair it with the selling tips on our fossils page to build the coin stack faster.

Once the bigger boat is yours, the new fossil islands and the open-sea activities listed above are the places your coin investment pays off.
