Emma and Martina Barry are the national Mirror champions, the sisters from Great Waldingfield having clinched the title at Poole Yacht Club at the weekend.
They are the first all-female crew to win the Mirror Nationals, which started in 1967, and the first sisters to lift the title.
Weather proved a crucial factor in this season's nationals, with only four races completed.
The sisters, who sail
from Brightlingsea YC, had two firsts, a second, and an eighth place.
Ross Kearney, the 2005 world champion, and Katy Jones, from Staunton Harold YC, Derbyshire, took second place
The first four scheduled races should have taken place at Llandudno YC over the May bank holiday weekend.
But winds gusting at over 30 knots meant only one race took place, won by Emma and Martina, with only half the fleet finishing and several boats suffering damage when they came in on the beach.
After a break of four weeks, the nationals resumed at Poole, where three races were completed on Saturday, the sisters finishing first, second and eighth – the last result being discarded.
More 30-knot winds ruled out any racing on Sunday.
Emma, 18, a pupil at Great Cornard Upper, finished her A levels last week, and had just one day's sailing between Llandudno and Poole. Martina, 12, is a pupil at Stoke-by-Nayland Middle.
The next target is the European championships near Gothenburg, Sweden, in August.
