Flipping is the job that decides how many cages a farm can run.
Floating cages are flipped so the mesh sits out of the water. A day in the air kills the algae and other growth that would otherwise clog the mesh and starve the oysters of flow. Through the season, every cage on the farm gets flipped on a regular cycle, by hand, from a boat.
We've talked with about 30 oyster growers across Canada and the United States. Flipping comes up again and again. It's manual, it's constant, and at scale it's the thing that caps how far a farm can grow.
SeaHand is built in Charlottetown by engineers working alongside an oyster grower who has 7 years on the water.
Our first machine flips cages without the crew doing the lifting.
It's built for farms where flipping is a scheduled job that pulls people off other work, not something one person handles on a slow afternoon.
First on-farm trials run in October 2026.
How many cages did your crew flip this week?
Got it. We read every one of these ourselves, and we'll be in touch as we pick farms for the next round of trials.
