The conditions for today's round over the Old Course at Troon were difficult due to a very strong cold wind.
Pamela Pretswell finished with a 77 to give her a 7 under par total of 218, 3 shots behind the winner, Amy Boulden of Wales.
The CSS for the 3 days was 77,77,78.
Pamela, leader by one shot overnight, shot four shots clear of the field with a brilliant birdie-eagle start but the Postage Stamp short eighth hole, only 118 yards long, added up to a lot of grief for Pamela.
"I was in the worst possible place to be at this hole ... bunkered on the left on the green. I had nowhere to go and it cost me a double bogey 5 in the end," said Pamela.
By the 13th hole, Pamela had lost her lead to Perrine Delacour, the French teenager.
Delacour birdied the 11th and eagled the 12th to surge first level then past Pamela But she could not shake off Boulden who came with a strong run of three birdies at the 15th, 16th, and 17th holes to beat the French favourite.
Pamela won the prize for the lowest score in round 2 and that for fourth, being beaten by the better inward half for third place.
France won the team title and runner-up Delacour won the Under-18s trophy.
Rachael Taylor finished on 232 after an 84 today. She shared the hole in one trophy with Chloe Ryan and Rachael Goodall who had holes in one today.
