I am sure that sailingfool has pegged this, but let me try to confuse you; I will use the chart at Tide Charts | Cape Cod Canal, RR. Bridge | Jun/2017 | Massachusetts
On June 1, 2017 High Tide at the Railroad Bridge at the WEST end of the canal is at 3:12 am, Low Tide is at 11:33 am, the second High Tide is at 3:46 pm, and the second Low Tide is at 11:47 pm. The canal is approximately 7 miles from Wareham to Sandwich. Floods East means that when the tide is coming in, the water flows toward the east.
DO NOT try to bring your new boat through the canal between 2:12 am (because it takes at least an hour to transit the canal at slack tide) and 11:33 am, as you will encounter a current that is against you. You can transit the canal after 11:33 am, but before 3:46 pm and the current will be helping you. For a really fun ride, plan to begin your transit at 12:30 pm so that you will be transiting the canal between low and high tide (maximum flood). You should see a 5+ knot boost to your SOG under power.
On the Sabre 28, mentioned in my earlier post, we transited the canal going west AGAINST the current. While we were making headway, I distinctly recall two women strolling along the canal next to us sipping out of Dunkin Donuts styrofoam cups. The Sabre's Volvo MD7a was running WOT, yet these women walked past us like we were standing still. I believe that this transit took us well over 2 hours.
We encountered two mating sharks at one point, and a sudden squall, later, while approaching the railroad bridge. Visibility in the squall dropped to under ¼ mile as we approached Mass Maritime Academy. I had ski goggles on when out of the wall of mist and rain appeared a car carrier less than ¼ mile in front of us! After all the excitement, we put into Onset harbor to collect ourselves and spend the night.
