Olympic sailors Stevie Morrison and Ben Rhodes are leading the 49er fleet at the halfway point of the Princess Sofia World Cup regatta in their first event since London 2012.
The British duo missed out on a medal in Weymouth last summer, finishing in fifth place at their home Games.
But they lead the way over Dave Evans and Ed Powys in Palma heading into the final three days of competition.
It is their first competitive outing since the Olympics after Rhodes suffered an injury during the winter, and the 31-year-old admits it has been a tough return so far, despite their lead.
"It wasn't really the ease in that the physios had recommended," he said.
"We'd done four days' sailing since the Olympics up until the day before yesterday so the 18 to 20 knots and big waves and four races were quite a shock to the system.
"But I stood up to it. So massive thanks to all the physios and strength and conditioning guys who've helped get me back in one piece."
Morrison added: "Obviously the racing's going to get a lot tighter with the standard getting higher and there's every chance that's going to pick up some of the rusty points in our sailing.
"If we can stay relaxed and realistic about that then there's no reason why we can't make some good decisions and still get good results."
Several of Morrison and Rhodes' fellow British sailors are also displaying good form, with Alison Young leading in the laser radial fleet ahead of Denmark's Sarah Gunni and Giles Scott one point clear in the Finn class.
There are also leads for Sophie Weguelin and Eilidh McIntyre in the 470 women's event and Paralympian Megan Pascoe in the 2.4mR class.
