Sitting in a white plastic lawn chair, staring intently through a pair of large, black binoculars, Charlotte Lau pulls a multicolored scarf high over her face and zips up her grey hoodie.
Down a steep staircase in the boat's main cabin, her boss Taison Chang sorts through the supplies piled on seats and a wide, curved table -- maps and charts, a GPS tracker, snacks, waterproofs, two-expensive cameras with long lenses, and several bottles of suncream in defiance of the dreary skies overhead.
Next to Lau, holding a walkie-talkie and shivering in a blue t-shirt, Viena Mak writes on a clipboard as her co-worker says: "no sighting."
It's a phrase the trio are becoming depressingly used to. They work for the Hong Kong Dolphin Conservation Society (HKDCS), which sends researchers out almost every day, no matter the weather, to search the city's waters for an ever-shrinking population of dolphins.
Their relentless work matters, not just to keep a few individual animals alive, but as a test of whether Hong Kongers can have more of a say in how their city progresses, take a step back from the mega projects and uninhibited development that have characterized Hong Kong for decades, and act to preserve what made it special in the first place.
