Coastal or Ocean Currents -  Do you know the difference?

Posted by Penny Haire on 27 October 2020 6:25:43 AM

Whatever craft you sail, currents can have a significant effect on your transit times across an ocean, particularly where the major ocean currents such as the Kuroshio and Gulf Stream flow. However, the beginning and end of most ocean crossings transit coastal waters, where there can be strong tides. Understanding how and why each type of current forms and where they occur increases the likelihood of a successful passage - whether it be a 'just-in-time' arrival on a ship or a podium finish in a yacht race.

New! Narragansett Bay high resolution tidal model

Posted by Penny Haire on 23 September 2020 10:12:43 AM

Due to high demand we have released a limited edition high resolution tidal model for Narragansett bay and Rhode island Sound in time for the Rolex New York Yacht Club Race Week.  The region covered includes all racing areas in the Bay and to the South at 110 m resolution at 60 minute intervals.

Data is available as GRIBs or PDF images like the ones below, for the North and South race areas.

The Best Weather Data Sources Available

Posted by Penny Haire on 27 August 2020 3:10:14 PM

For anyone that wants to start out using meteorological data for a planned application, it can seem daunting to look through all the different sources to try and figure out which one is best for your circumstances. A wide variety of options includes government-funded models, models from research institutions and also commercial and private institutes. So which is the best model?

Navigating the Strait of Gibraltar Tides

Posted by Penny Haire on 27 August 2020 3:10:10 PM


Suppose you're familiar with oceanography and some of the more treacherous shipping routes of the world. In that case, you'll know about the challenges for the shipping industry that the Strait of Gibraltar poses. This narrow passage that connects the Atlantic Ocean to the Mediterranean Sea has many elements that contribute to the complexity of tides and currents in this area, and this article explores how it all works.

'Won and Lost' in the Derwent

How tricky currents play a part in the closing stages of the Rolex Sydney to Hobart Race

The last few miles of a Sydney to Hobart race has often determined the ultimate winner. Capricious, shifty wind and 'bullets' - gusts that come screaming down the steep hillsides lining the course are often to blame. Not to mention the notorious night time 'shut-down' - where the wind disappears entirely.

The role of currents here has been overlooked - most likely because little information has been publicly available. This is set to change thanks to a new hydrodynamic model produced by the Coastal Environmental Modelling Team at CSIRO which Tidetech will be making available for the Sydney, Melbourne and Launceston to Hobart races this year as part of a package of Grib files and analyses.

Tidetech joins DNV GL’s Veracity

Posted by Penny Haire on 3 June 2019 3:35:00 PM

Tide and current data will be available to users of DNV GL’s Veracity web service after Hobart-Australia-based metocean data specialist Tidetech joined Veracity.
Tidetech will make its metocean data available to Veracity users as data or via an API, enabling shipowners and managers to optimise their fleet operations, save fuel and increase vessel efficiency. Tidetech is the only provider high resolution forecast modelling of coastal tides and currents, including in critical locations such as the Malacca Strait and English Channel where there is a significant influence of tidal currents.

Fuel efficiency and emissions bring next generation weather routing into the mainstream

Posted by Penny Haire on 2 February 2018 3:39:00 PM

 


Shipowners are embracing a new generation of weather routing tools as they look to optimise vessel performance in the face of higher fuel costs and looming environmental regulations. Metocean data provider Tidetech reports that owners are increasingly requesting high resolution data for regional trading patterns and coastal waters where tides and currents can have a greater impact on fuel consumption than on an ocean voyage. The renewed take-up of interest in weather routing is b
