Sailboat Routing 2020

We made it to the mouth of the Chesapeake Bay at 9:30 am on Friday and
made a 40 mile run for it to the Regent Point Marina near Deltaville and
we got there about 6:30 PM before the nasty wind started. Your guidance was perfect and the results were great.

Thank you and you can count on me using your service many times in the
future. You did a great job! … Kent Reidling

Super Gulf Stream Maps

Many thanks for the Gulf Stream maps and return routing suggestions. They helped out 2nd in class victory and a 5 day trip back. I look forward to meeting you (MB race).

“Surfing” the Waves

Good Morning! Can’t tell you both how wonderful it has been to have the use of Jenifer’s Gulf Stream and Dane’s wind all night long. Had the place all to ourselves too, no ships. We have been averaging about 10 knots and we see ourselves touching into the mid twelves when we surf ahead on a wave now and again. Thank you once again for your help. Chuck and Janet

Marion-Bermuda 2019

Jenifer, thanks again for an excellent read on the Gulf Stream. Your charts are must-haves for us when we set out on one of our races, and we always seem to do pretty well! Especially this year! Cordelia placed first overall, first celestial, and first in the short-handed division. Dane’s weather forecast was also spot on.

– Gail Greenwald

Will use you guys again!!

Of all the forecast tools we had available, yours was the ONLY one that nailed weather at our arrival, as well as weather enroute. It gave me a lot of confidence in you two to see thunderstorms, high winds and high seas between the GS and our destination. It also gave me ulcers and a lot more grey …

Thanks for your professional product and EXCELLENT customer service! I’ll definitely contact you two for our next trip up the ‘Stream. Gratefully, TD


Bermuda 2018

I’ve raced to Bermuda 6 times and each time we’ve had Jenifer and her charts with us. If there was ever a year to have “The Queen of the Stream” on board, 2018 was the year to do so. With so many features to the stream, especially south of the stream, it was incredibly helpful to have Jenifer’s charts and expertise. There were a number of very fine features and by and large, pretty darn close to where they were plotted by Jenifer. We were able to fine tune our way by carefully watching temp changes, speed through weather vs GPS speed and also by looking for clouds. A great help. Also of great value were her charts and analysis leading up to the race. It helped us define our strategy early on and then overlay wind/weather as race day approached. I have also found that many of the publicly available Gulf Stream resources are no longer available which makes Jenifer’s analysis all the more valuable.

I’ve been receiving Gulf Stream information from Jenifer since 2002 and would not attempt a trip without her support. Her routing has been far more reliable than any other source and she helps shave hours or days off of passages.

Ocean Charts

The stream crossing is, of course, the most critical…. and your information has been enormously helpful.  We have had remarkable experiences that prove that.  (On one)… we were running north on Egraine and crossed a 65 foot boat on the rhumb line.  He was chatty and assumed we would be left in his wake, given his longer waterline and more powerful rig.  For three days, following your chart, we zig zagged and crossed him several times, eventually popping up in front him by several miles.  By the end of the third day he wouldn’t answer our hails and didn’t want to talk to us.

Couldn’t have done it without you

Jenifer & Dane, we made it safely to Cuba after a wild ride across the Florida Straights! We are happy to report that we came in second in our division as well as second overall in our class (10 or so boats)! Thanks for everything, we couldn’t have done it without you two!

– Chad Knaepple

Very comfortable

We are comfortably resting in Cork, Ireland. Thank you for your excellent forecasting (across the Atlantic). It was a long and sometime rough trip but we all are in good spirits. With the crew returning home. Thanks again to you both

– Blair Pyne

Thanks again!

Thank u for all your help. your routing was excellent and in the final analysis it was the “blue line” as u predicted that helped us achieve our 3rd place in our class w/in our division.

– John Hummler

Very crucial

The ocean current and weather forecasts were essential in our winning!

Jenifer Clark’s Gulfstream produces standard ocean and weather charts and forecasts (from a purely science viewpoint) and produces waypoints as general guidance to the mariner indicating where favorable ocean currents are located. Each participant and crew understands and agrees that the decision to sail, start, select a course, or continue with a sailing race or voyage rests entirely with that boats skipper and crew, that sailing, particularly in an ocean, is an inherently risky venture and that no assurances are being made as to the safety of the event or trip as to the conditions that may be encountered, the seaworthiness or condition of any participants boat, the decisions made by each skipper and crew, or any other matter of any kind that could relate to the safety of each person participating and the property thereof.
