The popular free event on the Severn saw sailors and visitors alike in pirate fancy dress, and one of the new ships was decorated as a pirate ship complete with Jolly Roger.
The Black Pearl, with owner Dilwyn Jones at the helm, is a former fishing boat converted to be more fearsome. After its adventures in Shrewsbury, it will now be available for private hire.
On land meanwhile, members of the public were entertained by Morris dancing from Shrewsbury Morris, and music from the Chicago Swing Catz and the Shropshire Boatmen.
Organiser Dilwyn Jones said: "There were lots of people out on the banks, on the bridge, it was a cracking day.
"It's as busy as I've seen it. The kids loved dressing up as pirates, the mayor did the fancy dress competition.
"The weather was on our side too. All in all it was a great event, and hopefully everyone enjoyed it because that's what it is all about."
The popular duck race, open to the public, sold 700 tickets. And the Wildlife Trust sailed a boat, made completely of plastic bottles, from one side of the river and back again.
This year, the event raised funds for the West Midlands Search and Rescue Team, which was formed in 2007.
The event was organised by volunteers and supported by organisations including Shrewsbury Town Football Club in the Community, Salop Leisure, Salop Computer Centre, Salop Design & Engineering, staff from Marks & Spencer Shrewsbury, Team Shrewsbury, Shropshire Fire & Rescue, West Mercia Police and the RNLI.
