Sailing to Bermuda this fall? Get your weather information wherever you like; there is a huge amount available for free on the Internet.
Maybe it would be a good idea to hire a weather router; we have used three different ones over the years and they have all been helpful, within certain limits.
But get your primary Gulf Stream information from Jenifer Clark. Weather and ocean current analysis is a lot about pattern recognition and nobody, but nobody, at least as far as I know, has been looking at the Gulf Stream for as long or as often as Jenifer. Don’t leave home without one of her Gulf Stream charts—one of the best ways to spend forty bucks out there.
By the way, Jenifer and her husband, a meteorologist, also do weather routing and although I have never used that part of their service I would guess that they are pretty good at it.
