Re: C&D Canal

It's faster than I remembered. I walked through a sampling of the current stations (there are plenty - I didn't look at every one, but plenty to avoid surprises) and came up with timing. Note that I assumed SOG = STW = 6 kts so I did not take credit for current boost. If you account for that the time will be shorter than I calculated:

May 31, 2013 Worton Pt slack before flood 0957 so say 1000 (May 28 slack before flood at 0630 and 2030).

26 miles to Chesapeake City - 4.33 hrs @ 6 kts, pass at 1420, about an hour after peak current +2.3 kts

12 miles to Reedy Island - 2 hrs @ 6 kts, pass at 1620, 15 or 20 minutes before slack before ebb (note - ebb is now Delaware River & Bay ebb, not Chesapeake ebb, also note - reduce STW a bit through the canal to keep SOG about 6 kts to avoid getting here too early or take the boost early and and a short while in foul current before the Delaware boost builds behind you - depends on a trade of fuel consumption (slow down) or minimum total transit time (take the 2.5 kt maximum boost in the Canal and buck 1 kt for about an hour on the Delaware)).

21 miles to Ben Davis Pt - 3.5 hrs @ 6 kts, pass at 1920, about an 1-1/2 hrs into ebb, say -0.5 kts fair.

26.5 miles to Cape May canal entrance - 4.4 hrs @ 6 kts, arrive 2345, 2211 slack before flood & 0042 max flood +1 kt so 0.5 foul (note boost down the Delaware with 6 kts STW and average SOG of 6.5 kts puts arrival at 2315(ish) and results in less time in less foul current. Get SOG up to 7 kts average on the Delaware and you won't see any foul current.

Worton Pt to Cape May canal is 14 hrs or less with a total time in minor foul current of half an hour or so.

sail fast and eat well, dave S/V Auspicious
