AIB Tigers SC members Sarah Jane Smith (17), Michael Le Couilliard (15) and Daniel Galloway (13) will swim in age-group relays while Smith and Le Couilliard compete individually in 100 metre breast-stroke and 100m backstroke races respectively.
The trio are part of a 24-person team, competing for Hampshire in Division I, against county teams from England, Scotland and Wales.
Daniel Corden, Tigers head coach, said: ‘To be chosen for Hampshire is huge recognition for these swimmers and shows how strong swimming in Jersey is.
This is a big first step for them and hopefully they will take something away from the weekend and they can then move forward to higher competition like national representation.
‘The trio all raced well at last year’s Hampshire County Championships, which is where the team is chosen from.
‘They are training well at this early part of the season, so how they go this weekend will be a good indicator for the rest of the season.’
