Ask Your Virtual First Mate

Ask anything about your trip. Your Virtual First Mate answers from your own briefing, for you, your boat and your limits.

What will the current be doing along the way?

Current works against Vista for most of the run, then turns favorable near the end. On Leg 1 (Annapolis Harbor to Eastern Bay), a flood running N costs about 0.2 kt of speed. On Leg 2 (Eastern Bay to Miles River), a flood running NNE costs about 0.5 kt. On Leg 3 (Miles River to St. Michaels), the flood runs SW, with the current, adding about 0.6 kt to Vista's speed.

What should we expect at arrival?

Arrival at St. Michaels is forecast for about 10:47 am (allow 10:32 to 11:39 am), with NW wind 10 kt and seas under 1 ft. The briefing notes runs like this finish late more often than early, so the allowance runs long.

Where can we get in if plans change?

According to the briefing, Matapeake public pier, MD is available, 2.1 nm off the track on the Annapolis Harbor to Eastern Bay leg.
