When Murderboat Productions announced in September of last year that they would be building the “world’s biggest blanket fort,” it seemed ambitious. But, according to Guinness, that’s exactly what they did.

“Today Guinness recognized the official world record for largest blanket fort,” read a press release sent out Friday by Murderboat Productions. “A professional surveyor measured the completed fort at 6,736 s.f. and 146 sq. inches. The previous Guinness World Records record was 4,651 s.f.”

Muderboat partnered with blanket company Rumpl to create the huge blanket fort that included five domes, activities, games, DJs, an arcade and even yoga at the Oregon Convention Center on Dec. 8.

After the event, 25 “large bags” of blankets that were gathered in a blanket drive, as well as more provided by Rumpl and Murderboat, were donated to Transition Projects, an organization that helps people without homes in Portland find housing.

“I’m excited by what we accomplished as a community," says Shawn MacArthur, one of the event organizers, said in the press release.

Murderboat is known for staging big, extreme parties, including a dance party in a 727 in the woods and an upcoming topless tacos festival.
