Re: Current Position of Gulf Stream Question
Wed May 5 16:01:00 EDT 2010

George and Hank, many thanks for the information on the Gulf Stream position.

For anyone else who is interested, here is the info:

(1) [email protected] Frank Bohlen is a Professor of Oceanography in the Department of Marine Sciences at the University of Connecticut. For the past forty years he has been studying ocean and nearshore currents and transport. He won the Mixter Trophy as navigator of the winning yacht in the 1986 Newport Bermuda Race.

(2) [email protected] Professional Satellite Oceanographer Jenifer Clark and professional Meteorologist Dane Clark, both with over 30 years supporting the marine community, invite mariners to take advantage of their real-time ocean charts and weather forecasts for sailboat racing, boat deliveries, ocean cruising, and offshore fishing. Using infrared imagery, satellite altimetry data, and surface isotherm data, oceanographic analyses are produced and available for the Gulf Stream area and all the major currents of the world. Waypoints are also provided for taking advantage of favorable currents and for avoiding unfavorable ones.

(3) David Burch and Luis Solterto and Lee Chesneau would be people to ask and they are all associated with Starpath. There are also several other's that are part of Marine Wx education at StarPath [email protected]

(4) Herb Hilgenberg [email protected] Would be worth listening to see if he might be talking to vessels transiting a similar route to yours.

South Bound II, Herb, provides a daily ship-routing/weather forecasting service, as a hobby, on marine HF/SSB frequency 12359.0, starting at 2000 UTC until 2200 UTC or until completion of traffic. 8294.0 and 16531.0 are used as alternate frequencies as announced from time to time, subject to propagation Vessels are welcome to check in between 1940 and 2000 UTC, and should then stand by, until contacted again once their area gets covered. New check-ins should provide a short description of their location on checking in for the first time. At 2000 UTC, Herb will acknowledge all readable check-ins. Once on the South Bound II log, stations are encouraged to check in and stay in contact daily, until completion of passage. As part of the service each vessel is requested to provide current latitude and longitude to the nearest minute, when called back; also to provide true wind speed and wind direction, the barometric pressure, sea state and other pertinent data, such as sky conditions/squalls. Each vessel will receive daily, an extended four to five day route forecast, including way points, if necessary, to assist in avoiding potentially unfavorable conditions. Individual vessel forecasts are prepared in advance of air time, utilizing and editing numerical forecast models and other available data and products. Forecasts are provided as value added information, not as a copy or duplication of otherwise available or published offshore/high seas forecasts.

Fair winds, George Ray

Navy stuff is not as available as once was BUT the NOAA Ocean Prediction Center does provide a USN GS graphic at:

The graphic includes north and south wall locations as well as warm/cold eddy locations and sst.

In general,in my opinion the best ocean info on weather, currents, SSTs, high seas, etc are on the OPC site: see:

Let me know if I can be of further assistance. Hank

Current Position of Gulf Stream Question
Wed May 5 13:01:00 EDT 2010

If anyone knows a source of information about where the Gulf Stream is now (the center and width vary), or where it is forecast to be, please post a comment (blog comments are forwarded to me at sea now) or email me via the blog (my normal email address does not get to me at sea).

I thought this information was part of the (USA) National Weather Service High Seas Forecast, but I don't see it there now. Possibly Herb Hilgenberg mentions it on his broadcasts (12353kHz at 2000 UTC, I think), but I haven't been able to pick those up yet.

I am looking for something that preferably describes in words (ie, lat/lon) the current position of the Gulf Stream, or, if nothing else, a small (50kB or less) picture showing it.

hope this helps:
Maceió Ferryboatman
Wed May 5 12:01:00 EDT 2010, Maceio, Alagoas, Brazil

Aboard a Maceió ferryboat, Issuma is in the background. Only one oar is used to propel the boat. The motion of the oar takes a while to learn (I spent about twenty minutes learning, at the end of which was just able to move the boat along slowly), and is hard to describe in words. Rowing is always done standing up, to be able to put more force into it. Note the cigarette in his left hand--he has been doing this for years, so he is able to smoke and row at the same time :).

Maceió Ferryboat
Tue May 4 12:01:00 EDT 2010, Maceió, Alagoas, Brazil

Sturdy wooden rowboats like this one are used to ferry people, ice, fish and supplies to and from the fishing boats moored in Maceió harbor. Note the notch in the transom (back of the boat) where the oar goes--only one oar is used to row these boats.

The Colorful Waterfront of Maceio
Mon May 3 10:01:00 EDT 2010, Maceio, Alagoas, Brazil

Maceio, mainly known for its beautiful beaches, had a colorful harbor. The harbor is mostly full of small fishing boats, but also has tankers and cruise ships docking in it.

The sail on the right is on a traditional type of boat, still used for fishing today, called a jangada. More about these later.

I am a long way from Maceio, still enjoying the good winds of the stationary front I am near.

Some Wind and a Dolphin
Sun May 2 10:01:00 EDT 2010

Got some very welcome wind the last couple of days, passing thru a stationary front. The wind is getting lighter today, but it was very nice to sail quickly for a change.

The Lifting Keel
Fri Apr 30 10:01:00 EDT 2010

Rather than describe again that the winds are still light, I thought I'd mention some details of Issuma's lifting keel. Lifting keels are not common, but are somewhat popular on offshore and expedition-type sailboats. At the price of additional complexity (and cost), they allow the boat to motor into shallow water when the keel is up, and to keep the ballast (weight) low when sailing (when the keel is down) so it can still sail well.

Here is Yann's picture of the keel before being installed in the boat. The keel weighs 4.5 tons and also carries up to 600 litres of fuel.

On the lower left is the pin on which the keel pivots when raising and lowering. The upper left corner is the top of the keel (or the top aft corner of the keel when the keel is lowered all the way). The square shiny things are pieces of zinc, welded onto the steel keel to prevent corrosion.

Light Winds
Tue Apr 27 10:01:00 EDT 2010

I've had mostly light winds for the last several days, hot, sunny skies, and seas like this.

One Hundred Dolphins
Mon Apr 26 10:01:00 EDT 2010

This is a picture from about when I was crossing the Equator, and what seemed like one hundred dolphins swam by the boat. Some stayed as long as an hour, playing nearby. I've never seen so many dolphins together before.

Wow, must have been an awful sight, so when am I to expect you in Iceland ?
Trade Winds Tired Out
Sun Apr 25 0:01:00 EDT 2010

The Trade Winds have been great, gentle to moderate breezes from behind, pushing the boat along pleasantly. Today the Trade Winds got tired and decided to rest, so the seas are calm and I am doing a bit of motoring.

Welcome back to the Northern Hemisphere! How was your crossing of the ITZ and did you have a particular strategy for the crossing?
