I'm used to the cape cod canal. Interesting thing theres is the tidal difference between the buzzards bay side and the cape cod bay side is 3.5 hours so the current can be dead calm 4 times a day IIRC and it just rips thru there when it's not. Sailboats with diesels wait the tides to time it right. I think the minimum out board rating allowed is like 35 hp and at the wrong tide it's everything they could do to stay at a stand still fighting the currentnope, no anchoring involved, although there was a boat and an odd mooring setup. So, I'd say you are getting warmer...
You noticed the current, good catch. It goes by at ~7knots for much of a big tide cycle, quieting down for only an hour or so during slack tide. Bit of an interesting spot in a small boat.
Pulled a boat off the buzzard bay end. They were feet from the rocks and scared, they were gonna go down if we didn't yank them out. They had no clue what they were doing and didn't belong there luckily everyone was fine.
Amazing stripper fishing and blues there bonito and false Albies in the fall.
I've heard it claimed once a year some one surf casting from the shore in the canal will hook a tuna. Same out come everytime stripped bail snapped off. I usually run 40 lb braid surf casting there with a 6' 25 mono leader for shock and to snap off. I'll jig head and rubber eel the bottom feeling for holes or run a big Gibbs darter. Some times a yozuri crystal mag.
We head off the vineyard hedges fence to jig black sea bass. Out in the boat if were chasing strippers and blues we're often just chasing terns they're the fishermen we just follow lol
Did perhaps an overly aggressive Male or males decide you were a threat??
