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:

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.

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.
