Grand Blue Roblox: How to Get a Bigger Ship

The rowboat you pick up in Anchor Town gets you across the early water, but it has no weapons, no customization, and no way to park it. The larger vessel fixes all three, and it is sold in one place only.

Quick answer: Sail to Maple Village, find the ship dealer Mary at the Marine Dealership, and buy the larger vessel with money saved from quests. You cannot buy it on any earlier island.

Requirements before you buy the bigger ship

Three things gate the purchase: island access, a boat to get there, and enough money in your pocket. Nothing else about your build matters here.

Requirement	Detail
Island	Maple Village on Maple Island, reached from Clown Town’s port
Level range	Maple Village is the level 70+ stage of the main route
Starter vessel	The Rowboat from Anchor Town’s Boat Shop, unlocked by “Setting Sail” at level 30
Seller	Mary, at the Marine Dealership in Maple Village
Currency	Standard in-game money, earned from quests

There is no reason to rush the upgrade. The starter boat handles every crossing on the early route, so treat the bigger ship as something you buy once Maple Village is already open to you rather than a goal you grind toward at level 30.

Getting to Maple Village

Push the main quest line through Clown Town until it points you off the island. The route runs Anchor Town, then Clown Town, then Maple Island, and each hop opens through story progress rather than exploration.

Spawn your boat at the ship wheel on the dock. Boats appear at the wheel itself, not at random points along the shoreline, so standing on the beach and waiting will not work.

Sail east from Clown Town’s port until Maple Island comes into view, then dock. Set your spawn point in Maple Village once you arrive so a death does not drop you back across the water.

Saving money for the purchase

Quests are the reliable income source. Repeatable quests on each island pay out every time you turn them in, and Maple Village has its own repeatables from Gus and Nell alongside the main story rewards.

The mistake that stalls most players is spending on gear they will replace anyway. Skip mid-tier swords and cosmetic buys while you are banking for the ship, and hold onto Celestial Coins for Fruit Chests instead of converting your progress into short-term upgrades.

Buying the ship from Mary

Walk into Maple Village and locate the Marine Dealership. Mary is the NPC stationed there, and she is the only vendor who handles ship upgrades.

Press E to talk to her and choose the option about buying a new ship. The dialogue opens her stock, where the larger vessels sit alongside the basic option you already own.

Confirm the purchase. The larger vessel replaces your starting boat as the ship you spawn at the wheel, and you can check it worked by spawning it at the dock and looking for the mounted cannons on deck.

Note: if the option is greyed out or the purchase fails, it is almost always money. Grind another round of repeatables and come back rather than hunting for a second seller.

What the bigger ship adds

The upgrade is not just a bigger hull. It brings three functional systems the rowboat does not have.

Feature	How it works
Mounted cannons	Climb onto a cannon to aim it manually and fire at targets on the water
Anchor	Hold E while steering to drop it and bring the ship to a stop
Customization	The larger vessels support appearance options the starter boat does not

The anchor is the one worth learning early. Without it, a ship left drifting will wander off while you are on land, and holding the interact key is the only way to lock it in place where you docked.

Grand Blue is still in Early Access, so ship stock and prices at the Marine Dealership can shift between updates. If the vessel list looks different from what you expected, check Mary’s dialogue again after a patch rather than assuming the upgrade moved elsewhere.
