Retaining a Schools National sailing title is one thing, but to achieve a perfect score while doing it is a case of double elation.

Lu Junrui did exactly that yesterday when he retained the Boys' B Division byte title in the Schools National sailing championships at the National Sailing Centre.

The Raffles Institution (RI) student placed first in the starting three races and, despite dropping to sixth in the fourth race, he finished top again in the final one - which gave him a perfect score of four points, calculated using the best four positions in the five races.

The 16-year-old said: "It's actually my first time getting a perfect score in competition in my eight years of sailing.

"When I came back ashore and found out about it, I was quite shocked because the B Division is very competitive, but I also felt great."

In the Girls' A Division laser radial, RI's Bertha Han claimed her first Schools National title with six points - calculated using the best five positions in the six races.

Bertha, who has been a sailor for nine years, said: "I am happy and contented to finally have won the championship in my last year representing the school.

"The past few years I've been coming in second and third, so finishing off my last year with a bang is terrific."

The 17-year-old, who placed fifth in the same category last year, owed her victory to improved fitness levels and her ability to handle strong winds better.

RI were the big overall winners yesterday, bagging the championships in all three boys' divisions. Nanyang Girls' High School claimed the B Division byte title, while Raffles Girls' School won the C Division crown.
