Depart Cape May an hour or two before low tide to ride the flood, or at slack in the Cape May Canal.
Cape May Ferry Terminal low tide 10:39 AM
Artificial Island high tide 7:09 PM
Reedy Point high tide 7:44 PM
So ride the tide for about 9 hours to Reedy Point.
Maybe overnight at Delaware City or behind the Reedy Island shoal then ride the next flood tide through the C&D early the next morning.
September 18, Reedy Point low tide 2:32 AM and high 8:13 AM.
Or just motor through on Friday night, sunset at 7:08 PM, but the canal is fully lighted.
Assume for planning purposes motoring all the way from Cape May, then time under sail will be an added bonus.
The Hunter 31 if weather cooperates should make Reedy Point under 10 hours.
Cape May to Delaware City is two days for me with an overnight at Cohansey Creek.
