Well, I made my first round-trip voyage up the Hudson river for the year.
Ice-out is already happening. The icepack that choked traffic on the river and threatened to make heating oil scarce for the good folks of the Poconos region is breaking up and heading to sea after a couple of days of above-freezing weather.
It's pretty, anyhow, but noisy. Sailing over growlers and pack ice isn't terrible- there's a white-noise sound, and up on our bow there's some vibration and rumbling. When the icepack is breaking up, there are sections of clear water, and then the odd 20-foot by 20-foot chunks of ice that are two feet thick, and you know when you hit one of those bad boys. It sounds like a shotgun going off the next street over, then the vibration hits, then the resonance vibration, as the shock waves run through the hull and make the dishes and plates in the galley clatter- once when the shock wave hits, then about a second later when the shockwave bounces back to the bow and reflects back a second time to the house on the stern it happens again, a little more mildly.
Also, every now and again we hit one of those chunks square, run it down, and it just scrapes the whole way down the hull, like riding over a tall hump in your car, where you look in the rearview and pray like hell that you don't see the fuel tank in the road. Those are the ones that you feel through your feet and make the 'ooooh face. '
