Why use Tidetech in the Sydney to Hobart and other Offshore Yachting events?

We introduced our GRIB products one week before the start of the 2008 race. Of the 17 yachts which used the technology, 10 of them placed in the top 20. Quest's navigator, Bruce Baker said "We have found Tidetech’s info to be very accurate. This meant that on the Sydney to Hobart race we could use it in our tactical routing software with confidence and we believe that the information made a big difference to our overall result.

Will Oxley says: "The East Australian Current (EAC) often plays a large role in success in the Hobart Race. For years, an SST image from CSIRO has been an essential piece of information for navigators. Now Tidetech's commercial product takes this to a new level and Grib files for SST and current can be seamlessly imported into Expedition. I’ve been using Tidetech’s info about the East Australian Current for the last year and have found it provides a significant advantage. For a Sydney to Hobart race I consider the Tidetech product to be an essential part of the navigator’s arsenal."

We have learned a lot since we introduced our first current files . Since then we have had numerous boats use and win with our information for Australia, sourced from the highly regarded CSIRO.

What was new for the 2009 Race?


Building on what we learnt in 2008 from working with top navigators through the year, we developed a brand new technique to find the exact position of the fastest current using Sea Surface Temp.
For the 2009 race we offered:
  • Custom GRIB files for S2H race area
  • Full analysis of the expected current
  • A Briefing with Penny Haire and Oceanographer Dr Roger Proctor on the 24th Dec
  • Two months Free Subscription to all Tidetech's web products included
Or
  • Files Only
Why do you need the analysis and briefing?

Because the position and speed of the current changes continuously, even over a small area. Although the CSIRO Ocean current data is the best available information for Australia, it looks backward in time and only gives a 15nm res overall picture of where the current flow and major eddies are.

In the Lord Howe Race 'Charlie's Dream' found a 30% SOG advantage over just 4nm from faster current by being the right side of a temperature break (sharp change in sea temperature). More details here.

Only our near-real-time High res SST can show you where these breaks are and we will show you how to use this in your Nav Software to gain a competitive advantage.

Three of the top four champions after handicap used Australian Ocean current GRIB data from Tidetech including overall winner Quest, third place-getter Wot Now and fourth placed Yendys.

Navigator on Quantum Racing (which won their division and came sixth after handicap overall), Bryan Northcote said the current GRIB file provided by Tidetech is the most accurate he has used.

'I was able run the Optimum route using Expedition software for Quantum Racing using the Current GRIB in combination with four different Wind GRIB files. In reality the SST and current position & direction enabled us to confidently make tactical decisions regarding wind speed & direction that are more susceptible to change.
'At sea, the information contained in the current GRIB was very accurate. Any navigator or tactician using routeing software such as Expedition could not confidently use the Optimum route program without using a current GRIB file produced by Tidetech when comparing effects of wind and current to produce an optimum route.'

Lord Howe Race Temp

Charlie's Dream found the SST to be crucial. The latest data seemed to tie in well with what was seen from the temperature gauge and COG and SOG. As a temperature break was approached the current was at its' fastest, but dropped off rapidly as they went into colder water. What was clear was that even an image a few hours old would not show the position correctly, as the image below shows (it was 8 hrs old at the time). This is why we are producing files for S2H that are much more frequently updated. (Every 2 hrs approx, depending on recent satellite passes).
