A 22 year-old jet ski enthusiast from Chatteris was killed following a collision on a lake in Little Paxton.
The accident took place at South Lake Ski School on July 26.
Following the collision, Beki Hellens, a regular visitor at the ski school, was hauled from the water and taken to Bedford Hospital, but died a few hours later.
An inquest into Miss Hellens’ death has been opened and adjourned.
Her boyfriend Paul Turner, in a Facebook tribute, posted: “My beautiful, amazing girlfriend, partner and one true love Beki died at 11am on Sunday, July 26
“Wonderful daughter to Belinda and Richard, sister of Daniel, who she loved so very much and Jynx her poodle that Beki adored loved and cared for without limits or exception.
“She was doing something that she truly loved. I miss you so much it’s hard to breathe. I know we are two halves of the same star destined to be together again.”
A spokesman for Cambridgeshire police said: “We were called at 11.49am on July 26 by the ambulance service with reports of a collision at the South Lake Ski School in Great North Road, Southoe.
“A woman in her 20s was reported to be in cardiac arrest after the jetski she was on collided with another jet ski.
“She was taken by ambulance to Bedford Hospital but sadly died a short while later.”
A spokesman for Huntingdonshire District Council said: “The council is aware of this incident and we are liaising with the management of the club, Cambridgeshire police and the Health and Safety Executive to determine the need for an investigation under the Health and Safety at Work Act.”
A memorial service for Miss Hellens, who worked at Long Drove Dressage Centre, in Somersham, will take place at Fenland Crematorium, in March, at 11.30am on Tuesday.
Donations in memory of Beki may be made at the service, with the proceeds used for a memorial bench to be placed at the ski lakes. Remaining donations will be for Magpas Helimedix.
