GRIB Tidal Currents for Chesapeake Bay

Posted by Penny Haire on 4 June 2021 12:31:51 PM

We are very pleased to release a new model of Chesapeake Bay in time for the Annapolis to Newport Race! Sourced from NOAA the model covers the entire bay in incredible detail, showing for the first time the complexity of the currents everywhere in the Bay from Annapolis to Cape Charles, including the Potomac River.

Did you know that 90% of coastal seas have no tidal data available?

Posted by Penny Haire on 26 January 2021 9:59:55 AM

Traditionally, there has been little tidal information available to the public other than height predictions for major (standard) and minor (secondary) ports; even fewer tidal current predictions are available to Mariners other than a limited number of tidal diamonds and tidal stream atlases. These data have traditionally been published by official sources, such as Hydrographic Offices.  

Although useful for indicating conditions at the start and end of a journey, this data on its own doesn't provide the level of detail that mariners need for their chosen waterborne activity. In this article, we cover the traditional methods for tidal measurement and their shortcomings and modern technological advancements that can revolutionise the maritime industry in terms of tidal information.

The Currents in Singapore Strait are Extremely Complex. Here's Why.

Posted by Penny Haire on 25 January 2021 2:49:35 PM

At 16km wide, and stretching 105km long between the Strait of Malacca and the Karimata Strait, the Singapore Strait is a crucial gateway between Asia and Europe. Due to the high number of ships transiting the area, the Singapore Strait can become incredibly congested and requires a tight traffic management system to ensure that vessels are coming into port at the right time, every time.

36th Americas Cup - Auckland Tidal Currents

Posted by Penny Haire on 10 December 2020 3:20:15 PM

Like many sailing fans, we can't wait for the action to begin in the 36th Americas Cup in Auckland. Wind speed and direction, as you'd expect, will be the main factor that determines sail and foil choices, and of course, tactics on the course. What about tidal currents? With the speeds that these boats go, you'd be forgiven for thinking that current will be irrelevant.That's not the case though. Here's why:

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.

'Won and Lost' in the Derwent

Posted by Penny Haire on 6 December 2019 8:47:37 AM

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.
