Tidetech in Port Technology International: bringing water forecasting into port planning
Tidetech’s Penny Haire and Seb Mancini speak with Port Technology International about how high-resolution water-level and surface-current forecasts can help ports plan vessel movements with greater confidence, from S-100 trials to just-in-time operations.
S-100 gains momentum — what’s driving adoption, and what’s still missing
S-100 is gaining real momentum, though plenty of work remains before it becomes the global standard it's designed to be. We look at where progress stands, and the gaps still to close.
S-100 is a team effort — why hydrographic data standards depend on industry collaboration
S-100 adoption depends on more than standards alone. From data pipelines and validation to real-world testing, Tidetech explores why collaboration between hydrographic offices, technology providers and data specialists is essential to making S-100 work at scale.
Tidetech named Tasmanian Small Business award winner at 2026 Export Awards
Australian ocean data company Tidetech has won the Small Business award at the 2026 Tasmanian Export Awards.
S-104 and S-111 explained – how real-time tides and currents change voyage planning
Real-time water levels and surface currents are reshaping how navigators plan a voyage. Tidetech's chief scientist Roger Proctor explains why S-104 and S-111 treat tides and currents as live information rather than background context.
Tidetech named a Tasmanian Employer of Choice for 2026
Tasmanian ocean data company Tidetech has been recognised as an employer of choice by the Tasmanian government, one of a select group of organisations acknowledged this year.
Why “our data is 50 percent more accurate” does not mean anything in ocean modelling
How accurate is a hydrodynamic model? Tidetech's chief scientist Roger Proctor explains why the answer is never a single number, and what actually matters when judging model quality.
What S-100 means for ECDIS: from static charts to live navigational displays
S-100 is set to turn ECDIS from a static chart into a live, layered picture of the sea ahead. We explore how better bathymetry, water levels and current data will sharpen decisions on the bridge and in port.
Reading the current – our takeaways from the Australian Commercial Marine Conference
Two speakers stood out at last month's Australian Commercial Marine Conference — an economist with a frank read on Australia's fuel security, and an industry chief with the numbers to finally put commercial marine's economic case to government. Here's what caught our attention.
S-100 explained: what the new hydrographic data standard means for maritime navigation
The IHO's new S-100 data standard is moving from theory to practice, with live trials already underway in the UK, France, Canada and New Zealand. We look at how it's set to sharpen situational awareness on the bridge.
Whitsunday Islands tidal model now available for Airlie Beach and Hamilton Island Race Weeks 2026
Tidetech is pleased to release its high-resolution Whitsunday Islands hydrodynamic tidal current model for the 2026 Airlie Beach and Hamilton Island Race Weeks.
Newport-Bermuda 2026 — the Gulf Stream isn’t where you want it
Everyone who has raced to Bermuda knows the race is rarely decided by the straight line. It’s decided by the water moving underneath it.
A live step forward for S‑100 navigation in Australia
A live trial brings Tidetech's S‑100 navigation onto the bridge in Sydney, turning dynamic tidal and current data into real‑world decisions.
Hydrospatial 2026 — from standards to operational reality
Our scientific and technical director, Sébastien Mancini, was in Wellington for Hydrospatial 2026 in March 2026. Here's what he learned.
S‑100 readiness is bigger than any one data layer — that’s good for ports
The shift to S-100 is part of a wider rethink of how ports manage constrained water space, share information and make operational decisions.
How 2025 Sydney to Hobart winning navigator Andy Green uses Tidetech to win races
When Masterlock Comanche won the 2025 Sydney to Hobart, in the background was the quiet, methodical craft of Andy Green, the boat’s navigator.
Sydney to Hobart 2025 — will the Derwent decide it again?
The Sydney to Hobart is shaped by more than wind and sail strategy, with evolving ocean currents and eddies influencing conditions along the route. Discover how the East Australian Current and complex currents around Tasmania and the Derwent Estuary can affect race tactics, routing and the final approach to Hobart.

Whitsunday Islands tidal model for Airlie Beach & Hamilton Island race weeks
Tidetech’s high-resolution Whitsundays tidal model takes the guesswork out of navigating complex local currents. With 200m resolution and 30-minute time steps, the model reveals critical features such as back eddies, giving sailors the detailed data they need to make smarter strategic and tactical decisions during Airlie Beach and Hamilton Island Race Weeks.
Climate change: One slipping under the radar, the Thwaites Glacier
Thwaites Glacier is retreating rapidly, raising concerns about future sea level rise and the stability of the West Antarctic Ice Sheet. Discover what recent research reveals about the glacier’s accelerating melt and fractures, the potential impacts on global sea levels, and why improved ocean and sea level modelling is increasingly important.
GRIB tidal currents for Chesapeake Bay
