    Jason Tilley

A waterman from an early age, Jason credits his love for the ocean to his father, who is an avid sailor. Jason built his first board in college and rode it for many years in Oregon, then took it with him to Washington, Alaska, Baja, and a long stint on Maui. After graduating from the Northwest School of Wooden Boatbuilding, he migrated to Southeast Alaska where he found a life on the docks repairing wood fishing boats and yachts. For eight years Jason lived aboard a 26' wood cutter with his wife. They departed Alaska for a three year cruise, sailing and surfing their way to Panama. Returning to his native Oregon to start a family, they settled on the Oregon coast where he built a home and shop for making his boards. With an un-relenting passion for fine craft, wood, good design, surfboards, and boats, Jason has never been far from tools or the water.

I grew up a North Cascades snowboarder, eventually trading mountain adventures for coastal ones. Surfing and traveling in the Northwest, I discovered that certain board characteristics heightened my surfing experience on our unique waves.  Unfortunately, most off-the-shelf boards weren't equipped with them. This challenged me to create a better riding northwest surfboard and led me into my first garage shaping bay.  

After some trial and error I eventually landed on a few designs that gave me the feel I was looking for and Blackfern was born. A honest and humble backyard surf brand building boards one at a time in Portland, Oregon.  Through these handcrafted custom surfboards, my hope is to provide for and cultivate the pacific northwest surf community, paying homage to this unique and amazing place we call home.
