Itís roughly 175 nautical miles straight through. Iíd break it up into four legs: Portsmouth to Deltaville, Deltaville to Solomons, Solomons to Annapolis
, and Annapolis
to HdG. That divides it into segments of a little more than 50 nm each, which is doable in 10-12 hours if youíre able and willing to maintain 5 knots over ground as a minimum average cruising speed. This time of year itís possible to do 12+ hours in full daylight but soon it wonít be and I wouldnít be keen to cross the Susquehana flats and go into the HdG channel at dusk/dark. An alternative would be to drop the hook in Still Pond or the Sassafrass and do the last 12 nm on the fifth morning. This all assumes good weather as a moderate to strong northerly blow will make this trip quite a bit more difficult.
