Harvester

High tech,low hassle

An autonomous, electric ocean harvester built to lift sargassum out of the water before it reaches the shore.

Currently in concept development

The problem

Coastlines are being overwhelmed

Climate change is taking its toll on our coastlines. Nations around the globe, from Puerto Rico to Barbados, are witnessing record amounts of sargassum choking their shores. These invasive blooms devastate wildlife, threaten tourism, and even affect the health of locals.

The solution

Turning sargassum from a hazard into a resource

The Ocean Harvester is a scalable, autonomous vessel designed to collect sargassum offshore — before it hits the beach, decomposes, and becomes a public-health and ecological problem. Environmentally friendly, economical, and efficient, it's built to plug into a community-led sargassum management approach.

The Ocean Harvester, explained

01

Big impact, small emissions

Electric propulsion using proven aquatic technology — harmless to marine life and quiet in operation.

02

Stable at sea

Purpose-built for rough water conditions where most surface harvesters struggle.

03

100% autonomous

Unmanned operation, remotely controllable from the beach or from anywhere in the world.

04

High tech, low hassle

Designed for scalability, so a fleet can take on the capacity a region actually needs.
