Thieves have ransacked Rockingham Volunteer Sea Rescue Group's main patrol vessel, stealing over $20,000 worth of equipment.
The boat was broken into on Sunday night, with all of its electronic navigation equipment, life jackets and flares stolen.
"Taken were two Furuno Navnet 12 inch screens, six blue or black coloured PFD's that are marked RVSRG and our yellow flare container(with flares)," read a post on the group's Facebook page.
The rescue vessel, Jaimee Lee, had only recently been put back into service following a $100,000 refit.
"These people have stolen from a volunteer not-for-profit-organisation that relies heavily on the generosity of our sponsors, supporters and the public," read the post.
"We are extremely disappointed that Jaimee Lee now has to be taken back out of service."
Anyone with information on the theft should call Crime Stoppers on 1800 333 000.
