Steve visits Adam Campbell's North Haven Oyster Company on North Haven Island, Maine, after motoring from Rockland to escape heat and cruise ship congestion.5:55 The farm operates on a 17-acre salt pond over 25 years, and Campbell has developed a near-plastic-free oyster farming method using white cedar crates modeled on traditional Maine lobster crates instead of standard plastic mesh bags with floats.6:17

A controlled trial of 100 cedar crates versus 100 plastic bags, each loaded with 200 seed oysters, produced 11 bushels from cedar against 7 bushels from plastic — a 57% yield advantage.17:01 Campbell's hypothesis is that oysters resist cycling microplastics and off-gassing the same way they resist feeding during red tide events.17:55 Cedar crates also outlast plastic bags: plastic bags last 8–10 years; cedar crates are projected to last 20-plus years, with a cedar Maine pop buoy from the 1940s offered as evidence.18:20 Campbell starts seed at 1mm from a hatchery, grows it in an upweller, transfers it to cedar crates on the salt pond, then releases mature oysters below a tidal dam to grow naturally in the mud and eventually spawn wild.7:19 Steve notes that Jack (a cedar miller) and Scott (a woodworker with Arabella's stationary tools) plan to produce cedar oyster crates for sale.21:09 The departure from Rockland was timed around a weather window, with the Wakespeed regulator and alternator used to recharge batteries drained by Starlink and Robin's work equipment during a windless motor passage.2:46
