Starsand Port Construction

Starsand Port Construction is a main quest in the Island Life progression system that tasks the player with helping Marston rebuild the Maritime Bureau at Half-Moon Bay. Despite requiring only 15 Stone and 15 Softwood, it is one of the most impactful quests in the game because it unlocks the Merchant Ship (the best vendor for selling goods), yacht rentals, the Parrot Ship for deep-sea fishing, and is a prerequisite for the Building Starsand Station quest.

Step-by-Step Walkthrough

Step 1: Find Marston

Locate Marston at the run-down, dilapidated port in Half-Moon Bay. He is the dock manager and can often be found on the beach near the port area.

Step 2: Speak to Marston

Talk to Marston and agree to help rebuild the port. He explains what materials are needed for the Maritime Bureau construction.

Step 3: Deliver Materials

Gather and deliver the following materials to Marston:

Material	Quantity	How to Obtain
Stone	15	Mine rocks with a pickaxe
Softwood	15	Chop small trees with an axe

The material cost for this quest is notably low compared to other construction quests. Most players will already have these materials in their inventory.

Step 4: Wait for Construction

After delivering the materials, the quest objective changes to "Wait for port construction." The port completes construction the next in-game day (overnight). Simply sleep or wait until the following morning, then return to the completed port.

What Unlocks

Completing the Starsand Port Construction quest unlocks several major game systems, all accessible at the rebuilt Starsand Port:

Merchant Ship

The Merchant Ship docks at Starsand Port and operates from 08:00 to 22:00. It is the most profitable vendor in the game:

Item	Details
Sells items at premium prices	The Merchant Ship buys player items at 200% of normal vendor value (double the standard sell price).
Buying orders	The Merchant Ship posts weekly buying orders for specific items at an additional markup. Pickled goods are frequently requested.
Stock refreshes every Monday	The ship also sells rare items including food recipes and special goods.

Yacht Rental

Rent a yacht for 150 Coins per hour to explore the ocean and fish manually.
Boats are found on the left side of the dock near the Parrot Ship. A speedboat rental is available at the end of the pier.

Parrot Ship (Deep-Sea Fishing)

The Parrot Ship captain at the dock offers fast travel to three specialized deep-sea fishing zones:

Zone	Notable Fish
Coral Sea	Rare coral fish species
Luminwave	High-value deep-sea species
Celestwave	Tuna, Mola Mola, and other premium catches

These zones contain rare, high-value fish that require upgraded fishing rods and specific bait. Access to these zones is essential for progressing the Angler profession beyond the Apprentice tier.

Angler Profession Progression

The port is essential for the Junior Angler Trial, which requires the player to acquire a boat. Without the rebuilt port, boat access and deep-sea fishing remain locked.

Tips

Tip	Details
Gather materials before visiting Marston	15 Stone and 15 Softwood are trivial to collect. Having them ready lets you complete the quest in a single visit.
Prioritize this quest	The Merchant Ship alone is worth rushing this quest for, as selling goods at 200% value is the best money-making method in the mid-game.
Save high-value items for the Merchant Ship	Once the port is built, hold onto pickled items, Golden/Silver Poop, and processed crops to sell at the Merchant Ship for double profit.
Check buying orders weekly	The Merchant Ship's buying orders refresh every Monday and offer substantial bonus income for specific items.

Known Issues

Item	Description
Material delivery may be skipped	Some players have reported the quest saying "Wait for port construction" immediately after speaking to Marston, apparently skipping the material delivery phase. The port still auto-completes the next day.
Marston unresponsive	Marston can occasionally get stuck talking to tourists and become uninteractable. Workarounds include taking the ferry, waiting a full day, or advancing to the next season.

NPC	Role	Location
Marston	Dock manager and quest giver	Starsand Port, Half-Moon Bay
Solara	Gives the follow-up Building Starsand Station quest	Community Center
Delphin	Fishing Mentor; Angler trials require port access	AquaBlue Outpost
Neona	G-Power Bike shop; sells boat blueprints	Main road near Half-Moon Bay
