“It is great to support something fun for the community, something a little different and a little quirky.
“I would like to thank Wild Encounters for all their work with the event, including ticket sales and ferry transport.”
It took seven ferry trips to transport all the people over to the island.
To qualify for the attempt, all participants had to wear a full penguin costume including a head piece with a beak attached, black and white body suit and webbed feet.
Participants had to be filmed arriving on the island and filmed while two independent witnesses counted them.
All photographic and written evidence will be provided to Guinness World Records and will take up to eight weeks to be ratified.
The record is then uploaded to their website.
