Tours on the popular blue and white pleasure boat will return on Monday, so owner Dilwyn Jones had the 28-ton vessel lifted for checks.
An all-day operation starting at 6am saw a massive crane attached the to boat before it was raised from the River Severn onto Frankwell car park.
Inspectors checked underneath to make sure all the moving parts were in working order, and gave it a clean bill of health.
The boat was back in the water at around 5pm.
Dilwyn said: "We're governed by the Maritime and Coastguard Agency and they do an inspection twice a year to make sure we can run safely.
"Every other year we have to take the boat out of the water for them to examine underneath and check the propeller and other working parts. They make sure there's no rust and the hull isn't degrading.
"We swapped a cutlass bearing and did a couple of other bits and now it's ready to go for the season.
"We'll be back up and running on Monday. There are restrictions still, so we'll only have the top deck open. We'll be doing table service.
"Then on May 17 we'll be able to do a bit more, take booking for private parties and events.
"I think everyone is looking forward to getting back to a bit of normality."
