surging through the bridge arches of the main Dublin to Belfast railway line, across the estuary, through which the Broadmeadows river flows. During a full moon, the high tide causes a nearly 4mtr high wall of water, a standing wave, although we don't see that here this time. However we had fun surfing the waves and practicing your balance, until I took a swim that is. With no 'river bank' to get to, it was a 20 min swim before I got back in the boat!! ... kayak roll eskimo silverbridge club ...
