Sam Shoemaker made a kayak entirely from mushrooms.
Mushrooms! What next?
This week I chatted with Ann about a class where she learned to use mushrooms for natural dyes. And you may remember a post, here, about human caskets made from mushrooms.
But, wait! There’s more, says Open Fung, a nonprofit advancing the future of fungi-based technologies, materials, and the arts. Their latest endeavor: making a kayak from mushrooms.
Lisa Kwon reports at the Guardian, “On a clear, still morning in early August, Sam Shoemaker launched his kayak into the waters off Catalina Island and began paddling. His goal: to traverse the open ocean to San Pedro, just south of Los Angeles, some 26.4 miles away.
“But upon a closer look, Shoemaker’s kayak was no ordinary kayak. Brown-ish yellow and bumpy in texture, it had been made – or rather, grown – entirely from mushrooms. His journey, if successful, would mark the world’s longest open-water journey in a kayak built from this unique material.
“With his phone, GoPro camera, walkie talkie, and a compass affixed to his life vest, Shoemaker left shortly before 6am in order to avoid the worst of the swells in the forecast. But three hours in and powering through his ninth mile, the coastline still out of sight, Shoemaker began feeling seasick.
“Suddenly, he heard the sound of a large animal breaching the waters. To his left, a fin whale flashed its glistening tail, then trailed slowly behind him. As the 50-ft creature followed him for three more miles, Shoemaker found the strength to finish out the maiden voyage … which took him 12 hours.
“As he stumbled onto shore with his mushroom kayak still intact, the artist and mycologist embraced his friends and family. …
“Shoemaker began his career as an artist creating sculptures with propagated mushrooms. Upon returning to Los Angeles after graduating from Yale with an MFA in 2020, he began exhibiting artwork that captured the unique behavior of mushrooms as they grew out of hand-built ceramic vessels and blown glass. … Shoemaker now belongs to a small community of scientists and artists exploring the potentiality of fungal innovation as an alternative material that could be used in everything from kayaks and buoys to surfboards.
“Their focus is on mycelium … a pivotal connective tissue in the animal kingdom. Mycelium-based materials in an aquatic context are known as AquaFung, a term coined by Shoemaker’s mentor Phil Ross, an artist and the co-founder of a biotechnology company called MycoWorks that engineers mycelium-based materials including a mushroom ‘leather‘ that can be used in furniture, handbags and biomedical equipment. After cofounding MycoWorks, Ross cofounded Open Fung. …
“Ross argues that AquaFung has many of the appealing properties as plastic – such as being lightweight and buoyant – but without the harmful footprint. …
“Shoemaker began working on his first mycelium boat in 2024. …
He modified a used fishing kayak to serve as his fiberglass mold, then grew the mycelium network inside the mold …
“Shoemaker meticulously dried the resulting kayak composite structure using fans over the course of several months. …
“Confident in his prototype, Shoemaker began searching for appropriate support. Shoemaker met Patrick Reed, the lead curator of the Pasadena-based arts organization Fulcrum Arts, in December 2023 through mutual friends. After a studio visit, Reed was blown away by everything that the artist had to show him. … Shoemaker completed his second mushroom boat in June; grown from the same wild Ganoderma polychromum mycelium. …
“The completion of Shoemaker’s boat marks the second ever water-tested mushroom boat to be made after Katy Ayers, who holds the Guinness World Record for growing, then testing, what was then the world’s longest fungal mycelium boat on a Nebraska lake in 2019.
“ ‘A lot of people really didn’t think it was possible,’ says Ayers, who grew her boat after being inspired by a documentary called Super Fungi. …
“Ayers and Shoemaker credits mycology pioneers like Ross for making the technology more accessible. And mushroom-based materials are slowly beginning to pop up in the mainstream: In 2021, Stella McCartney made headlines with its launch of the world’s first-ever garments made from lab-grown mushroom leather, in consultation with Ross.”
