Sharkbuoy PPK & PPP GNSS Tide Buoy

The Sharkbuoy is a state-of-the-art buoy designed for measuring GNSS tide in Australia's tough conditions. It is built by surveyors and metocean specialists who understand the importance of reliable and accurate data collection. With the Sharkbuoy, you can log raw GNSS data for post-processing, or receive Marinestar G4+ for real-time PPP tides.

We've designed the Sharkbuoy with a focus on reliability, toughness, and ease of use. Its solar power with battery backup ensures endless logging, and its durable construction can withstand even the harshest of weather conditions.

The newly developed Sharkbuoy MkIV

Sharkbuoy tough...

Developed based on years of experience

The buoy can be attached directly to a mooring or, in high-current scenarios, a Norwegian buoy can be rigged to take any load off the Sharkbuoy's GNSS sensor (as shown). Every buoy comes with a 12kg counterweight chain that should always be used to maintain a constant buoy draft.

To ensure easy recovery via a grapple or hook, we recommend rigging the twin small floats at least 20m from the Sharkbuoy. For optimal performance, we suggest using a 15-25 kg anchor or 100kg clump weight (depending on currents and seabed type).

The Sharkbuoy can be ordered as a standalone unit or with a mooring system customized to the required water depth. Our buoy and mooring system are designed for easy recovery using a capstan or drum winch, with quick-release floats that enable the entire mainline and chain to pass through a wide block or onto a winch drum.
