18th Century Dutch Oil on Canvas Depicting a Harbour Scene

A good Dutch 18th Century painting depicting a busy harbour with a sailing ship flying the Dutch flag.
It is skilfully painted with much detail in bright colours and an early evening sky.
This very atmospheric painting is in good condition with no damage or paint losses.
There is some age related crackling but the paint is all stable. It is housed in a later gilded antique frame.
Circa 1780
