Lucas managed to take the top honour yesterday after race 11 was cancelled due to a lack of wind in the air.
"This is the dream, this is definitely the dream," thisisdorset.co.uk quotes Lucas as saying. "It is absolutely fantastic to have achieved it, I'm just really, really pleased.
"One of the key things all week was to try to stay our of the protest room, keep it simple, keep it clean and try not to get any disqualifications or false starts.
"I've got a great team behind me, the GB sailing support team is fantastic and make sure we got out on the water properly prepared, mentally and physically, and that no stone has been left unturned."
Lucas was the only woman competing in the single-person keelboat event.
