The alarm was raised just before 1pm on Thursday, 1 February, after the man suffered a severe cut to his hand on board a vessel in the middle of The Wash.
HM Coastguard tasked Hunstanton lifeboat to go to the man's assistance and its volunteer crew were paged to launch.
RNLI lifeboat Spirit of West Norfolk took 20 minutes to reach the boat, where they assessed the man's injuries before bringing him ashore at the lifeboat station, where a colleague was waiting to take him to the Queen Elizabeth Hospital in King's Lynn for treatment.
Jeff Lenton, one of the Deputy Launching Authorities at Hunstanton RNLI, said: 'From an operational point of view it all went very well.'
After returning to station, the lifeboat was washed down and made ready for service.

This year marks the 200th anniversary of both the founding of a lifeboat service at Hunstanton and the founding of the RNLI, whose work would not be possible without donations from its supporters..
Since Hunstanton's current station opened in 1979, its inshore lifeboat Spirit of West Norfolk and her predecessors have helped save 140 lives and render assistance to more than 600 people who found themselves in difficulty or in danger.
In 2003, she was joined by the hovercraft Hunstanton Flyer, which has since then been launched 250 times, saved 13 lives and assisted a further 150 people.
The station is one of just four around the coastline who operate a hovercraft.
