Locks Heath scared off the opposition in the Portsmouth Halloween Meet at the Mountbatten Centre.
There were some frightfully fast swims and monster personal bests from the 21-strong team.
Locks Heath amassed nine golds, 10 silvers and 13 bronze medals over the two days of competition.
They also clocked 66 personal bests as well as a clutch of qualifying times for the Hampshire Championships next year.
Scott Hutin, 10, and Shannon Lamb, 11, collected six medals each.
Hutin carried off two golds, while Lamb raced to three victories.
Evelyn Hall, 10, went home with five medals – including one gold.
Meanwhile, Thomas Larby, 10, and his 13-year-old sister Jessica grabbed four apiece, with the latter winning one gold medal.
Mia Day, nine, earned a medal of each colour and 11-year-old James Hall took two breaststroke bronzes.
A further gold went to May Fletcher, while Jan Stoop and Hannah Roberts also topped up the haul.
Other fine performances came from Ella Richardson-Fitt, Amelia Ayling, Shona McGrath, Harrison Kennedy, Lucy Briscoe, Gracie Pick, Sarah Barbary, Isabel Barbary, Eve Limburn and Evie Selby.
Earlier this month, Kyle Kirkland and Joshua Beaudro starred at the James Moreno Level 2 Open Meet.
The pair, who have just turned 10, were competing over 100m for the first time with Beaudro grabbing a gold and a bronze and Kirkland a bronze.
