Swimmers Information

Thanks for your interest in our weather and ocean routing service. We have been providing professional advice to swimmers for nearly 40 years and have handled many Atlantic and Gulf of Mexico swim attempts and would be glad to assist you in your upcoming adventure. Most notably we were a part of Diana Nyad’s Team that supported her 5 attempts to cross from Havana to Key West from 2010 to 2013, with the final attempt in 2013 accomplishing her life-long goal.

Our service for swimmers includes pre-trip consultations for the selection of the optimal weather window (unlimited and usually by phone) and then right before you depart we provide catered weather forecasts, ocean maps, and recommended waypoints (sent by e-mail) to help you take advantage of favorable ocean currents and avoid unfavorable ones. We also offer enroute updates to keep your team informed on the latest weather and ocean conditions.

Jenifer Clark’s Gulfstream

Website Designed by
Wattz Web Design and Marketing

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. Therefore, each person participating in these type events assumes all risk and responsibility of participating and sailing, and to the fullest extent allowed by law, equity or admiralty, releases, forever discharges and forever waives each and every claim that each person may have or come to have, whether known or unknown, against Jenifer Clark’s Gulfstream (JCG) including Dane and Jenifer Clark, from any and all claims, suits, or causes of action of any kind, however denominated, whether sounding in law, equity or admiralty, arising out of or relating to the event.
