|New NWS link on our home page|
We have added a link to our home page (or will do so shortly) from which you can conveniently find your local weather both on land—which is what shows up—and on the water. If you are near the water there will be a "Marine" link to the left of the land data and you can click that to get local marine weather.
There is an advantage to going straight to the NWS with a link like this rather than just looking for weather at your location in a search engine. The latter will end up with tons of commercial sites that have simply taken the NWS data and embedded into their ads, and often in not as convenient a format.
|New portal to nautical chart products|
Now it is easier than ever to locate and view nautical charts, either for paper purchase or for the free download of the electronic versions. See nauticalcharts.gov/viewer. There is a new online viewer and links to new catalogs online and now in pdf format organized by state. Very nice indeed.
We still need to go to the chartmaker site to get the electronic downloads, and we can still look forward to them streamlining that process some, but there is clearly much motion in the right direction here.
Also try www.nauticalcharts.gov for links to several new services and products, and note these web addresses are in transition.
|New shortcut to NWS weather page|
There are many webpages for NWS marine weather and some are complex links. One new shortcut that forwards to a main index page is weather.gov/marine. This is also a good link to remember for finding "city weather" for various places and get straight to the NWS data rather than the overprocessed presentations of various companies.
For some reason it does not link to the Ocean Predictions Center, but you can quickly find it from google OPC+NWS. Likewise you can get to National Hurricane Center by google to NHC+NWS and to the National Data Buoy Center with NDBC+NWS... but the main index given above will get you to links to most of the NWS marine data.
It pays to keep this index in mind and to check it frequently, especially the FAQ section, since they keep this up to date. For example you will learn that the Dial a buoy system is now down (Oct 14) and that the ftpmail for buoy observations is also not working at the moment. See item 3 in the FAQs to learn about ftpmail.
Other good links to note are oceanweather.com/data for a quick overview of conditions around the world
franksingleton.clara.net for an excellent set of up to date worldwide links, including much on grib data, sources and viewers.

|New World Record for Seattle Rowers|
Four Seattle rowers have just entered the Guinness Book of World Records as the first team to ever row unassisted across the Atlantic from mainland US to the mainland of UK. They completed their (just under) 69-day voyage on Sunday, August 20, 2006. The four rowers, Jordan Hanssen, Dylan Le Valley, Greg Spooner and Brad Vickers, rowed from New York Harbor to Falmouth Harbor and in the meantime won first place in the inaugural Transatlantic Rowing Race. The finish line to the race was a 42-mile meridian segment, whose north end was 4 miles south of Bishop Rock Lighthouse. The midpoint of the line (06 27 W, 49 27 N) is about 72 miles from Falmouth Harbor. They crossed the finish line within one mile of the precise center of the line, with the nearest competitor 250 nmi behind them and the next nearest back 550 nmi.
In fact, they could actually claim a more encompassing rowing record as the first vessel in recorded history to ever row across the Atlantic and end up precisely where they said they were going. All rowers headed for England in the past ended up in Ireland or took a tow before ending up in France, or they just stopped wherever they crossed the Bishop Rock meridian and took a tow to UK.
After following OAR NW closely over the past two months, it is easy to see why it has been so difficult to maintain a chosen course in the past. These ocean going rowboats are very sensitive to wind and waves, not to mention ocean currents. Ocean currents though just some 0.5 to 0.75 kts on average away from main streams, do not normally affect larger vessels, power or sail, but they mean a lot to a boat whose average speed in a seaway is only 2 kts or so. And contrary to areas like the Gulf Stream where predictions are remarkably good, these random ocean currents cannot be predicted—despite all the efforts of the super computers and extensive satellite data.
The OAR NW team managed to succeed where others were less successful because, first, they are exceptional rowers (a champion rowing team in college) with exceptional conditioning and training, and, second, they took careful advantage of all the latest weather and oceanographic resources available to them, many of which were simply not available just three or four years ago. They did it technically right and they were well prepared, but it still must boil down to exceptional courage, stamina, and comradery... and it can never go unsaid when crossing the ocean in any small vessel, they were blessed with more good luck than bad.
We are especially happy about their achievement because the four rowers studied navigation and weather tactics in great detail at Starpath School of Navigation for a long period in preparation for this race. Besides GPS and the latest satellite communications and weather resources, they also each learned celestial navigation and ocean routing, including in depth studies of the Gulf Stream, which they negotiated admirably to great advantage. They also took the uncommon position that each would take an equal part in the navigation and tactics, so each one studied all the topics. It was a good philosophy for such a venture, as they did not know who would be required to do what, when, with two rowing at all times.
They obviously learned their lessons well. We are immensely proud of this team. They had adverse conditions throughout much of the race and in fact had "Hurricane Alberto" pass directly over the top of them—it was not technically a hurricane because of its high latitude at the time, but by the time it reached them it had documented winds of over 70 kts, far more than it had as a tropical storm in FL and the Gulf of Mexico (it takes just 64 kts to be a hurricane in lower latitudes).
They also had the bad luck of a totally unusual High pressure system centered just west of UK once they got close, which brought north winds for the last two weeks of the voyage. They had to fight for every mile to guard against being pushed below the Finish Line. Had they not had to pass through that latitude gate of the finish line of the race, they would have had the chance to set still another record of the fastest 4-man row across the Atlantic finishing "anywhere" on the longitude of the Bishop Rock Lighthouse. The record for that is 60 days and 16 hr set in a similar vessel in 2005, which crossed the meridian far south of the newly imposed latitude gate, off the coast of France.
At the time the Seattle vessel was positioned to go for that record they could have blasted off in a SSE direction to cross the line roughly where the record holders had crossed it, but they had to tread water and claw their way north in preparation for a forecasted long period of strong northerlies. If they did not do that, they would not have been able to get through the latitude gate of the finish line.
So the record to the Bishop Rock meridian had to be given up in lieu of the bigger prizes of winning the race and being the first to go where they said they were going. It was good navigation discipline. It is, after all, a basic tenet of good navigation to arrive at your intended destination.

|OAR NW doing well in Transatlantic Row Race|
Four Seattle rowers and students of Starpath School of Navigation are doing well in the first ever Transatlantic Rowing Race. They are the only American entry, and are now leading the closest boat by about 200 nautical miles. They have about 900 miles to go as of July 22. You can follow the progress of the race at official row race web page and read about the Seattle team at OAR Northwest. We wish them the best and we are very proud of our students and friends. They are doing a super job.

|Translations of Emergency Navigation|
Our textbook on Emergency Navigation has been in print in the first edition for more than 20 years. Work on the second edition is now in progress in collaboration with McGraw Hill (available in Mar, 2008).
Work on the French edition has been underway for some time now and first half of that book is available as an ebook. When the American editors learned that there may also now be a German translation, they sent us a short movie about maritime communications as a reminder about translations.
