"I suppose it's a sign that it's probably about time I got out there and cleaned her up," Dunedin nurse Gerard Kenny said.
"The funny thing is, I was down at the yacht club last week and I saw there were a few gulls hanging around it. But I didn't notice that they were nesting on her."
"We try to get out most weeks, but we haven't this year. We've both just been too busy," he said.
"We've had a lot of fun in it. We spent two weeks bringing it down from Auckland about 10 years ago."
The 10m Australian Lock Crowther-designed trimaran was built on Waiheke Island between 1972 and 1974 and still holds several records for North Island races.
"It was quite the boat in its day. It's won a couple of coastal classics. It's won the Auckland to Gisborne race and the Lyttelton to Wellington race in its life," Mr Kenny said.
"We've won the Dunedin to Oamaru race in it a couple of times, too. It's a pretty quick boat when it's set up. We've had her up to 17, 18, 19 knots."
Mr Kenny said the gulls should not plan on getting too comfortable.
"It's a good prompt to get out there and tidy her up and get out sailing again."
