Finalizing our initial itinerary. Need to get to northern side of Tortola. Quick math puts me 11 Nm downwind to Sopers the 5 up to CGB. Aboard a 52Cat, assuming 7 knots speed.

1.5 hrs to West End, 1 hr up to CGB (motor), estimating up puts me at 3 hrs sail time.

Assumptions correct? Hows the downwind ride in the channel end of March?

Thanks.
