Look up Atkinson Grimshaw, he did some amazing night scenes of harbours and the sea such as:
'Scarborough Bay'
'In Peril'
'Nightfall Down the Thames'
'At Anchor'
'Lights in the Harbour'
'The Lighthouse at Scarborough'
Also Turner painted some breath-taking water scenes:
'Fishermen at Sea'
'Fishermen upon a Lee-shore, in Squally Weather'
'Ships Bearing up for Anchorage'
'The Shipwreck'
'Keelmen heaving in Coals by Night'
'Slavers throwing overboard the Dead and the Dying, Typhon coming on'
'Peace - Burial at Sea'
'Rough Sea'
'Snow Storm - Steam-boat off a Harbour's Mouth making Signals in shallow Water, and going by the Lead. The Author was in this Storm on the night the Ariel left Harwich'
Two of my favourite artists.
