A blind 74-year-old water-skiier took to Lake Windermere in a protest against a new 10mph speed limit.
Gerald Price, from Stockport, skied at 28mph to test the new bylaw on England's largest lake.
The ban at Windermere was imposed in March 2005 to reinstate the natural tranquillity of the lake.
But Mr Price believes the Lake District National Park Authority limit breaches human rights laws.
Enforcement officers turned up to gather evidence and interview the driver of the boat, Kevan Furber, 51, from Manchester.
Mr Furber had to make two journeys in excess of the speed limit, as enforcement officers only gave him a warning for the first time.
Mr Price, who set a world speed record for blind water-skiing at Windermere in October 2004, said: "We have been robbed of this enjoyment in the Lake District along with thousands of families.
"It's unjust, unfair and unreasonable. You tell me any other sport where somebody with my disability, my age, my problems, could go out to take part in something that's as exciting and enjoyable as what I've just done. I really really enjoyed that ski."
