It was the most bizarre episode of EU referendum. Eurosceptic firebrand Nigel Farage and Remain-supporting rock star Sir Bob Geldof battled it out on the River Thames over Brexit in June.
Bemused Londoners and tourists looked on as up to 60 boats took part in the protest and counter-protest from Remain vessels.
The pro-Brexit flotilla was organised by the Fishing for Leave campaign, which has resumed its operations and told IBTimes UK it does not rule out another Thames style-stunt.
"Well, you never know. We will wait and see, who knows, it depends what happens,"
Alan Hastings, a spokesman for the Fishing for Leave group, said.
"Ideally, it's our belief that the government could actually use fishing to show that they've done a good job of Brexit, if they've got enough gumption to do so.
"If they don't, well, we will see where we have to go from there."
The campaign is opposed to the EU's Common Fisheries Policy (CFP), which sets quotas on how much member states can catch. "In Mrs May's words, Brexit had to mean Brexit," Hastings added. "We've got to see that we do get a good settlement [from the EU], that's equitable and includes all of the industry.
"The CFP is a policy that is universally derided as an abject failure. That's the last thing we want to see when we've got such a golden opportunity to rejuvenate British fishing."
But Labour warned ahead of the referendum vote that quitting the EU could severely impact the UK's fishing industry.
"Our EU membership provides access to Europe's fishing waters worth £100m ($130m) to the UK and British fishing boats are able to land and sell their catch in any EU country," said Kerry McCarthy, then shadow environment secretary.
"If we left the EU we would still want to trade with EU countries, negotiate access and quotas outside our own territory and share fishing rights for UK waters."
