About Tidetech

Tidetech is an Australian ocean‑data company specialising in high‑resolution tidal and metocean intelligence. Since 2008, we’ve worked at the point where rigorous science meets real‑world maritime operations — helping navigators, hydrographic offices, port operators and technology providers make better decisions in a changing ocean.

Where we began

Tidetech grew from a simple problem: despite decades of oceanographic research, the maritime sector still lacked reliable, accessible data — especially tidal currents.

Co‑founders Penny Haire, a professional mariner, and Dr Roger Proctor, a coastal oceanographer, saw first‑hand how that gap affected operations. Bringing together practical seamanship and scientific depth, they set out to turn under‑used research capability into operational tools.

We began in high‑performance sailing, where precision matters most, before expanding into enterprise‑grade metocean services for commercial shipping, hydrographic agencies and maritime technology firms. Today, our data supports users worldwide — from national hydrographic offices and shipbuilders to optimisation technology providers, Olympic and America’s Cup teams, and chart producers (and a very large technology company with wearable devices...)

What we do

We provide scientifically robust, operationally practical metocean data — built for organisations that rely on accuracy.

Our core capabilities include:

Hydrodynamic and tidal modelling — high‑resolution models, observational data assimilation, tidal constituents and predictions
Data analysis and transformation — turning raw scientific datasets into navigational, operational or regulatory‑ready formats
Cloud‑based data infrastructure — resilient systems, automated pipelines and multi‑region model orchestration
Data delivery services — APIs, high‑volume feeds and S‑100 aligned services for enterprise customers

Everything we build is designed to be dependable: scientifically validated, operationally tuned and scalable.

How we work

We stay deliberately focused. Privately owned and headquartered in Hobart, we’ve grown organically — building a team that blends oceanography, engineering and software expertise. Our approach is collaborative and understated: keep the science strong, keep the data reliable, and support partners over the long term.

Who we work with

Our data powers applications across:

Hydrography and chart production
Shipping and vessel optimisation
Coastal planning and risk assessment
Marine technology and digital navigation
Elite and professional sailing

From global tech platforms to national hydrographic offices, we support organisations that need consistent, high‑quality ocean intelligence.

Why Tidetech

Ocean data only becomes valuable when it’s usable. Our role is to make complex science operational — to bridge research, technology and day‑to‑day maritime decision‑making.

That mission sits behind everything we deliver — modern modelling systems, S‑100 aligned services, and tools that help ships, regulators and coastal communities navigate with greater certainty.

Meet our team

We are oceanographers, data and systems specialists and sailors.

Penny Haire

CEO and Co-founder

Penny has had a long career in the maritime industry, as a sail trainer and Chief Instructor for the Royal Yachting Association before founding Tidetech with Roger in 2008. Having grown up near Liverpool UK which has one of the largest tidal ranges in the world, she has always been fascinated by tides. Her passion is to be able to make scientific research about weather and oceanography more accessible and usable for everyone in the maritime world and for Tidetech's data to be used to help reduce harmful emissions from shipping.

Dr Roger Proctor

Chief Scientist and Co-founder

Roger is a coastal oceanographer with more than 40 years’ experience. Prior to Tidetech, he worked for over two decades at the UK Natural Environment Research Council’s Proudman Oceanographic Laboratory (now National Oceanography Centre). He lead the Modelling and Observation Systems for Shelf Seas programme and created the Liverpool Bay Coastal Observatory.

He developed POLCOMS — one of the most influential shelf‑sea modelling systems of its era — and was later director of the Australian Ocean Data Network (AODN) within Australia’s Integrated Marine Observing System (IMOS).

Sebastien Mancini

Scientific and Technical Director

Sebastien is a physical oceanographer with two decades of experience in coastal and regional modelling, marine data management and digital infrastructure. His career spans engineering consultancy, scientific data operations and national marine observing programs.

At AODN he led technical strategy, rebuilt the national marine data architecture, implemented data standards, and managed a team of 25. At Tidetech he guides scientific direction, infrastructure development and the next generation of global modelling systems.

Dr Christelle Auguste

Senior Oceanographer

Christelle is an ocean engineer and coastal modeller specialising in hydrodynamics, sediment transport and climate‑change impacts. Her doctoral research developed detailed 2D/3D models for Banks Strait, and her work at Tidetech focuses on storm‑surge dynamics, tropical cyclones and global tidal systems, with a strong emphasis on climate resilience and coastal risk.

Other team members include talented oceanographers and specialist developers.
