Gulf of Finland: how the place works

From December to March there is ice that drifts with the wind and packs into fields. The gulf freezes from the east, and a change of weather can close an open lead within a day. Icebreakers keep the ports clear, not the water between them.

Gulf of Finland: what breaks there

Drifting ice cuts into the hull, and the pressure at the waterline is the real problem: GRP takes an impact but not sustained pressure. At the berth the ice presses boats against pontoons and piles.

Gulf of Finland: what this means for your policy

Ice pressure and drifting ice are excluded in many sets of conditions or tied to requirements such as a bubbler system. Anyone leaving a boat afloat there over winter needs explicit written agreement.
