New model - Key facts
After the disappointing outcomes of the COP26 meeting in November to address the IPCC 6th Assessment requirements over the coming decades, a potentially more immediate existential threat to global sea level rise was discussed in a press conference at the American Geophysical Union Fall Meeting in December. Titled “The threat from Thwaites: The retreat of Antarctica’s riskiest glacier”, the hour-long presentation discussed the mid-term status of the International Thwaites Glacier Collaboration (ITGC) 5-year study into the stability, or rather instability, of the Thwaites Glacier or ‘Doomsday Glacier’ in popular terminology.
Are you entering the 2021 Vineyard Race?
The complex strong tidal currents at the eastern end of Long Island Sound can be challenging for even the most experienced race navigators.
Key questions need to be considered. Will you depart Long Island Sound via The Race, Plum Gut, or The Sluiceway? What are your tactics for the return back into Long Island Sound on the way home? How you negotiate these complex and strong tidal currents could be the difference between a good race and a Great Race.
Fortunately, Tidetech has accurate high-resolution tidal current forecast models for the entire course available in GRIB format. This allows you to make the best navigation decisions giving you more time to simply sail fast and gain an advantage over your closest competitors.
The prestigious Rolex Fastnet Race is just a few weeks away, and competitors who have the most accurate data on hand will be able to make the best possible decisions for the fastest route.
The Fastnet is genuinely a navigators' race, as it challenges competitors to negotiate some very tricky tidal situations - such as whether to head offshore for pressure or tuck inshore to avoid the worst of an adverse tide. This year's race is exciting because it's finishing in France for the first time, and the last section involves negotiating the notorious Alderney Race, with currents of up to 9 kts.
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.
At approximately 110 miles long, with a large population base on its' shores and abundant natural beauty, Long Island Sound is one of the busiest waterways in the United States. As you can see from the image below most vessels navigating the Sound are recreational, although there are also numerous passenger vessels and fishing traffic.

The creation of ocean current maps depend on the measurement of sea level, which is the base level for measuring elevation and depth on Earth.
The English Channel is home to some of the strongest and most complex tides in Europe. It is one of the most heavily trafficked locations in the world, with many different types of vessels transiting east and west through the Channel or crossing between ports in southern England and Europe.

No matter how advanced technology becomes, weather forecasting will always carry a degree of uncertainty. Nature is unpredictable, but by combining powerful technology with data, we can produce reasonably reliable evidence-based forecasts for up to ten days.
