Ashley Yearwood collected Bermuda's only individual swim medal, adding to two earned by the relay teams, as she snatched a bronze on the last night of competition at the Idottscenter pool.
Yearwood placed third in the final of the 50 metres backstroke in 31.33 seconds, bettering her qualifying time of 31.62.
The sister of fellow squad member Nicole, she was one of five Bermuda competitors who competed in finals last night, all of them improving on their morning heat performances.
Morgan Hopkins placed eighth in the 100 metres Individual Medley in one minute 09.79 seconds, slashing almost two seconds off her heat time of 1:11.44.
Nicole Yearwood meanwhile made a similar improvement in the final of the 100 metres freestyle, touching the wall in 1:00.84 to place sixth after clocking 1:01.44 in the qualifiers.
Nathan Frick, the Island's sole male competitor, was timed in 24.61, placing eighth in the final of the 50m freestyle after finishing in 25.20 in the morning heat.
And in one of the last events of the night, the 4x100m Medley team placed fifth in the final, knocking seven seconds off their heat time.
Rebecca Heyliger, Hopkins and the Yearwood sisters were timed in 4:37.09 after qualifying in 4:44.13.
Malcolm Smith set himself up for an enthralling last day in the Laser Standard Rig when he finished second and third in the seventh and eighth races of the week-long regatta yesterday.
Before Wednesday's rest day, Smith had finished on a high on Tuesday with a third and a first, and his last four results have now put him firmly in medal contention.
But now everything will depend on today's last two races after which the 24 sailors in the fleet will be able to discard another result.
Smith currently sits in fourth place on 30 points but will be allowed to throw out his first-race finish, when he came tenth.
Above him on the standings are first-placed Oscar Dannstrom of Alandwith 19 points, Dominic Breen-Turner of Ynys Mon with 20 and Luke Breen-Turner of Ynys Mon with 23.
All four will have plenty at stake when they sail on the waters of Eastern Harbour today.
Bermuda's other Standard Rig entry, Brett Wright, finished an encouraging third in the seventh race yesterday but then followed that with a 13th which he will probably throw out.
He's currently lying in sixth with 45 points.
No official results for the Laser Radial Rig or the Boardsailing classes were available last night.
Competitors had also been scheduled to sail two races, but the first was eventually delayed because of a lack of breeze.
Sara Adderley lies in third place and Rockal Evans seventh.
Alex Jones, Bermuda's only Boardsailor, was fifth after six races so far.
