But that life has helped her turn a hobby into a small business.

Ms Creighton, who grew up on Cape Barren Island, spends most of her nights at sea on board the Searoad Tamar.

She is a Seafarer Integrated Rating and is the only female on board the ship, which operates between Devonport and Melbourne.

Ms Creighton's days are usually spent loading and offloading cargo from the ship or driving it in and out of port, but when she has downtime between shifts, you will find her in her cabin creating jewellery.

"In between times, you've got to have something else to do," Ms Creighton said.

"You're either sleeping or down socialising with the crew, but you've just spent all day with them so I like to have my own little hobby in my cabin."

Jewellery making is a tradition Ms Creighton learnt from her mother. And as of last week, her Divacre products are for sale at the Blue Apple Gift Store and Gallery at East Devonport.

"It feels pretty special [to have them on display and for sale]," Ms Creighton said.

"My mum used to make shell necklaces and then I just started making them and then went into making earrings and I haven't looked back."

As an 11-year-old, Ms Creighton would use shells her farmer father had collected for her during shearing trips.

Ms Creighton now uses shells, pearls and abalone shells she has collected from her own travels.

Most of her shells are from Cape Barron Island, but other items are from Europe, Korea, Japan and Pacific Islands; just some of the places she has travelled in her 20-year seafarer career.

Ms Creighton said she applied for her first seafaring job - a job her father also initially did before the family moved to Cape Barron Island and he became a farmer - while studying fisheries and aquaculture at the Australian Maritime College.

She said there weren't many other women doing the same Integrated Rating line of work she did.

"I've only ever met two other women in my time in 20 years at sea" she said.

"It is physically and mentally demanding sometimes for a woman to be on board a ship on her own and you've got no other people to talk to about girly things.

"But I don't think as if I'm the only woman on board, because everyone treats me just like anybody else."

Ms Creighton said while she did often become the go-to person to talk to about sensitive issues, she really enjoyed life at sea.

She said she enjoyed it because she worked one month on and one month off, which gave her plenty of time to enjoy other hobbies, such as learning to fly.

The Blue Apple Gift Store and Gallery is in Wright Street, East Devonport.
