The bit of land on the east side of the junction of the river Hull and the Humber, where the Deep is now squatting, was once a large ship yard run by one Martin Samuelson. In the 1850's and 60's about one hundred steam vessels were made here by Martin Samuelson and Co before they sold out to another company and moved onto other business. Samuelson's name however became attached to this spit of land and Sammy's Point it remains.
I came across this oil painting of the shipyard, painted from the other side of the river, on the BBC's site where it is wrongly named (nobody's perfect).
