  • SAILING TOTEM

    Shoutout for how well the log we used on this passage performed in those conditions. @backstay.marine's Offshore Logbook lived in the cockpit from Hawaii to the Marshall Islands and was doused a few times, but it's printed on paper that's basically impervious to getting wet (anyone know Rite in the Rain? Yeah, that stuff!). Impressive!

  • JOHN KRETSCHMER

    We broke out a new logbook, big stuff on Quetzal. We are trying the Offshore Logbook by backstay.ink. Previously we filled several ‘Sailor’s Logbooks’ from Starpath. Most entries are by the crew, at least after every watch. The best log-keeping award definitely goes to father/daughter team, Lauren and David Kriet from our Patagonia passage last year! Our logbooks tell a long story, 22 years of voyaging on Quetzal and 200,000 miles.

  • PELAGIC BLUE CRUISING

    🪛Detailed project notes including photos, materials, and costs
    ⛽️Fuel efficiency and fill ups
    💦Water consumption rates
    ⚓️Favorite anchorages
    🪨Uncharted hazards (on the rocks, anyone?)
    🗺️Navigation notes from locals
    🎣Fishing gear for the area

  • SET FOR 24-HOUR SAILING

    Experience the convenience of a full sailing day on a single page. And to make it even better, we have summary pages where you can record each day's progress.
