The Ancholme Head of the River event brought hundreds of rowers and spectators to the banks of the river last weekend.
Ancholme Rowing Club members, who hosted the event at their Manley Gardens headquarters, did not take to the water as participants so great was the need for volunteers to co-ordinate the event.
It attracted just 23 boats to compete in 1986, but this year a huge entry of 168 crews participated, racing on a course which took them from Broughton Bridge to Point End Motorway Bridge.
Rowers came from 15 different clubs from throughout Lincolnshire and Yorkshire.
Ancholme club representative Jim Copson said: “We are victims of our own success in the growth of the event.
It now attracts so many rowers to come and take part that our own members have to sacrifice their own row and give themselves over to running the event to ensure safety and good organisation.
“We need about 35 volunteers to run the head race smoothly and that is about the number of members we have. We have to have people to marshal the event and we are grateful to our members for doing that.”
Boston Rowing Club official Jeff Elms, who took part, said: “This is a splendid event which attracts a lot of rowers and the organisation is spot on.
“It is a credit to Ancholme Rowing Club that it runs so smoothly, all rowers love coming and it is in the real spirit of the sport that the organisers give up their row on the day to ensure the event runs smoothly.”
However, Ancholme rowers enjoyed success the week before at the Doncaster Head race with all three crews winning.
The men’s four comprised Jim Copson, Iain Mcleod, Darren Earley and Ron Norton, while the ladies’ four had Gail Copson, Panny Barker, Jo Porter and Teresa Evans in the boat with cox Bill Timms. Both crews then combined to win as an eight.
