The number to start with on Aqua Nera is 1.5. That is her draft, in metres, on a hull sixty-two metres long.
Everything about the vessel follows from it. The Peruvian Amazon is not deep water; it rises and falls several metres a year and its interesting channels are the shallow ones. A ship that draws a metre and a half can follow a tributary that a conventional hull has to watch from the main river, and can put its skiffs into flooded forest at first light rather than after an hour of transfers. Draft is the difference between seeing the Amazon and passing through it.
She was delivered in 2020, built in Vietnam and designed around the black-water lagoons that give her the name — nera, for water that runs the colour of tea under a low sun. The exterior is unadorned: a long, low steel hull with a full-height window band, a covered promenade running its whole length and a shallow observation deck on top. From a distance she looks less like a yacht than like a well-drawn piece of infrastructure, which is a compliment.
Inside, the register changes entirely. The main lounge is dark timber, grass cloth and rattan, arranged around a broad leather ottoman with the river filling three walls of glass. A brass-fronted bar stands at one end with its bottles lit from behind, and the room turns over through the day: coffee at six before the first excursion, a long empty middle while everyone is out on the water, then the part of the evening where the guides sit down and explain what you actually saw. Beyond it are a proper restaurant under a coffered ceiling, a billiard room hung with botanical prints, a games room with four chairs around a backgammon table, and a spa with a single treatment bed.
The twenty suites are the quiet triumph. Each takes the full window band, so you wake with the forest at eye level rather than through a porthole; each has a chaise set into the window, a dressing area behind a screen and a bathroom in dark mosaic. They can be made up as doubles or as twins, which is what lets her carry forty guests without any of them being downgraded. Nothing in them shouts, and the palette — charcoal, sand, tarnished brass, a single botanical print — is deliberately quiet against what is happening outside the glass.
The operation around that is the real product. Forty-four crew serve forty guests, a ratio that would be extravagant at sea and is simply necessary here: naturalists, skiff drivers, a kitchen sourcing most of what it cooks from the river and the villages along it. Excursions run twice daily by skiff, by kayak and on foot, and the vessel repositions overnight so that each morning starts somewhere new. On deck, a plunge pool sits under a shade canopy on the top deck, which after a humid morning in the forest is not a decoration.
Aqua Nera charters the Peruvian Amazon from US$435,000 per week, whole-ship. It is one of the few places where chartering the entire vessel is the normal way to do it.
