we have two on our docking system and they are the frame sitting on the bottom type. the better of the choices out of the way of ice. they are on a alternating time so not to run 24 hour straight every day for 4-5 months.
They definitely do not stop ice flow, but we had pylons put out in front of the docks in line with the slip fingers and we need to have some re-driven every year or so because they take the brunt of the damage but having free water around the docks instead of the ice softens the blows to the pylons and the docks for sure because there is room to move.
we are south east in Paugus bay in the corner near the Margate, always the direction of the wind either coming from Lakeport or across the bay, everything comes our way
