A team from Newhaven Coastguard was also involved.
The casualty on the beach was ‘successfully extracted’ to an ambulance, a spokesman said.
The spokesman said: “Thank you to Shoreham Port for your kind assistance.”
Later that day, the crew was tasked to a report of a capsized dinghy off the coast in Brighton.
The casualty vessel was towed in by a safety boat from Brighton Sailing Club and no medical intervention was required, the spokesman said.
“Another busy day for the team,” the spokesman said.
