What a moored buoy really costs
The buoy is the small part. Once you add the anchor and mooring hardware, a vessel to deploy and recover it, seabed permits, and the maintenance visits a mooring needs over its life, a serious metocean or oceanographic buoy runs from hundreds of thousands of pounds into the millions. And when the question moves, the mooring does not: repositioning means a fresh deployment campaign.
What you get instead
A Scout USV measures wave height, period and direction, wind, sea surface temperature, pressure and salinity, and carries acoustics and your own instruments in an open payload bay. It holds position as a virtual anchor for months, then motors to a new site on command. No mooring permits, no anchor infrastructure, no maintenance dives, and no dedicated deployment vessel: one person launches it from a slipway, beach or boat, large or small, and Scout transits to the site under its own power, even thousands of miles offshore.
When a moored buoy still makes sense
A fixed mooring is the right tool when you need a permanent reference station in exactly one place for years, or a surface-piercing structure to host instruments that must stay put. A relocatable USV is the better tool when coverage needs to follow the work: multiple sites in a season, campaign monitoring around a wind farm or vessel, or filling gaps between fixed assets.
