Crews from Windsor Boys School Boat Club enhanced their rowing reputations with some fine performances at the National Schools Regatta in Dorney.
The J15s quad A team reached the final after putting down an impressive qualification time and fought back from fourth place at the 500m mark to pip rivals Maidenhead RC for first by just 2.6seconds. Grange School in Hertfordshire finished a length further back in third. The B and C crews also both finished third in their respective final races.
Mark Wilkinson, director of rowing at the school, said: "The boys executed their race plan with extraordinary maturity.
"It would have been easy for them to panic when they were trailing the leaders early in the race and pulled through powerfully in the second half of the race to earn a well deserved victory."
The National Schools Regatta is one of the premier regattas of the season for young rowers and thousands came from all corners of the UK to test their mettle.
The crews then merged to create two boats for Saturday's eighth races. Both qualified well through the time-trial but failed to make it through to the finals, the rigours of the previous day's racing catching up with the teams.
Julian Van Gelderen was a medal prospect for Windsor in the boys singles championship, having finished eighth in the European Junior Championships in Essen, Germany just a week previously.
This view was enhanced as he won his semi-final and, in an eight boat final, he steadily pulled away from a competitive field to take gold.
Wilkinson added: "Julian demonstrated again that he is the leading junior u18s sculler in the country and well on course for GB representation this summer.
