The Boiler Tides

Product details

  • Paper & printingEnhanced Matte paper — a luxurious flat matte surface with sharp detail and rich colour. Printed using archival pigment inks on professional Epson equipment. Each poster is individually inspected before shipping.
  • FramingFrames are sustainably sourced solid wood, handmade in New Zealand, and arrive ready to hang with hardware pre-installed. Glazing protects your print. UV protection and anti-reflective coatings can be added on request.
  • DataPublished tide predictions from the Bureau of Meteorology Pacific Sea Level Monitoring Project. The poster maps an annual high and low tide pattern. Predictions may come from a representative station; conditions at a specific beach can differ. Check the official tide source before making decisions on the water.
  • EditionEach poster captures the complete tidal rhythm of your chosen beach for a full calendar year — the patterns shown will never repeat exactly the same way again.
