If I were you, I'd head
down to Hampton or Little Creek and wait for a front to come through. After the front passes the winds usually clock to the SE and are light as a High moves in, so you can motor-sail out of Hampton Roads
into the Atlantic. If you leave at noon, you should be across the Gulf Stream
by sundown the next day. Make sure to check the forecasts for what may be coming next, because the next front will likely catch you before you get to Bermuda
. I recall
seeing systems with winds up to 100 knots out there in March a few years ago--sent 15' swells all the way down here to Nevis
. Your IP 35 should able to handle the "normal" weather
you might see in March; just watch out for the extra-strong systems.
The Gulf Stream current
and the cold eddies east of the Stream are factors to consider. Pick a narrow point in the Stream to cross, if you can. Once across, you can gain or lose a couple of knots in the eddies. There are a number of sources of info. You can hire Jenifer Clarke to come up with a custom route
for you, or you can try to figure it out for yourself.
