Gilt framed dutch seascape oil painting

An antique oil painting on canvas featuring several Dutch ships at sail. Superbly painted and bearing the signature F Greef lower left hand corner. The painted details of passengers on board the ships is amazing and you can see a village with church steeple on the distant shore. Nicely framed in a modern French rococo giltwood frame. The painting is most probably Dutch 19th century or earlier and is mounted in a gilt 20th century frame.
