Slack Waterfolk and maritime music · Port Ellery

Slack Water · a folk and maritime music festival · 28 to 30 August 2026

Everyone who said yes, still findable after it ends.

Slack Water is three days of folk and maritime music on the waterfront, the last weekend of August: fiddle tunes in the net loft, shanties on the pier at dusk, boats you can climb into. The QR on the back of your badge asks one question: would you like to be in the festival’s Pool, for the weekend and after? Say yes, and the person you talked to at the fiddle workshop can find you next month. Say no, and nothing happens.

Tickets pay for the festival. Nobody pays to be in the Pool or to be introduced.

The weekend

Three days on the waterfront

Three stages within a short walk: the net loft, the chandlery tent and Pier 3. Slack water is the still hour when the tide turns and boats can cross the bar. For one weekend a year, everyone crosses paths.

Why people come back

Before, during, after, and next year

A festival is worth what it leaves behind. These are the four reasons people open the Pool again, and none of them needs a trick.

Before

See who else is going

Buy a ticket and you can tick a box to get the Pool’s question early, by email. Say yes and you are listed before the gates open, so people can see who else is coming, each with their own yes.

11 of this year’s 18 said yes before the gates opened.

The Pool, in order

During

Find the person from the fiddle workshop

Everyone who said yes is in one list you can ask in plain words: who plays bass, who has seats to Seattle, the fiddler from Olympia. Only people who said yes can come up.

6 said yes on their badge during the weekend.

Ask the Pool

After

The Pool stays

On the Monday after, the festival office handed the Pool to Birdie Novak, a volunteer, and stepped back. A month later it is still here, still active, and everyone in it is still findable.

1 more said yes at home, inside the 14 days a badge’s question waits.

A month later

Next year

The people who come back

Returning people are marked beside their names. Seb Marchand told his own page to say yes to next year’s Pool for him; he will get a notice when it does, and he can undo it.

6 of this year’s people were in the 2025 Pool too.

Who comes back

  • No countdown on this site. The dates are the dates. There is no clock ticking toward them, and no “only a few left”.
  • No streaks, and no “we miss you” emails. Birdie writes to the Pool when there is news, like next year’s dates. Some months nothing comes, and nothing is wrong.
  • No paid list of who is coming. Anyone can read who said yes. Nobody can pay to see more, or to be shown first.
  • No sponsors scanning badges. The QR on your badge opens your own question and nothing else. There is nothing on it for anyone else to collect.
  • No feed to scroll. The Pool is a list of people who said yes, in the order they said it.
  • Leaving is one action. From any message or from the Pool page, any time, and it takes effect within sixty seconds.

Five Pools

One for everyone, three for the people who do things, and last year’s

Each is a Kindling Pool we host: a public file anyone can read, listing people who said yes. You can be in one and not the others, and leave any of them in one action.

Shifts 2, 3 and 11

Why this needs an open protocol

A closed attendee app is worth only as much as the people it signs up, it starts empty every year, and when the festival is over the list belongs to whoever sold the tickets. On Kindling, each person’s page stays their own, the Pool is an open file anyone can host and any client can read by its members’ consent, and a volunteer can keep it after we step back.

  1. Shift 2 · a new app starts fullFamiliar Faces and Bellows could read the Pool on day one.

    On the Monday after, someone opening Familiar Faces for the first time found the people from the weekend already there: the ones who said yes, each still deciding who may write to them. Bellows showed the rides home. Neither app signed up a single festival-goer. They read our public Pools, which any client may do §3 §3.5, and every person’s own rules still apply §5 §7.

  2. Shift 3 · one room, many doorsThe same Pool, through any door.

    Our list, a sheet taped up at the info tent, a group in Familiar Faces and a ride card in Bellows all read one file, pools/slack-water-2026.json. We do not mind which door you use, and no door can keep you in. The interface is anyone’s; the Pool is the protocol §1.2.

  3. Shift 11 · it outlives its makersA festival is three days a year. Its Pool is not.

    A festival app lasts as long as its contract. Our Pool is a file with a named keeper, and when a keeper stops, the protocol says what happens next: quiet after 90 days, never deleted, and any active member may take it over §9. Last year’s Pool is showing that right now.

Bellows

Which apps can read our Pools. Familiar Faces, the friendship and groups app, reads Slack Water 2026, Session Players and Crew and Volunteers. Bellows, for asks and offers, reads Rides Home and Session Players. Heartwood shows Slack Water 2026 in its Friends room and Session Players in its Music room, Face Up deals Session Players in its Bandmates deck, and Card Catalog files all five in its drawers, last year’s included, by what each is for. Sundial opens each of them under its own name, and so do Face Up and Heartwood for the ones their decks and rooms don’t cover: the crew and the rides home, and in Face Up both festival lists too. Any other client may read a public Pool too §8.1. Every person still decides who may write to them, and every client honors the same two block lists §7.3.

The money

Tickets pay for the festival. That is all.

What a ticket pays for

  • The musicians, who are paid for every set.
  • Three stages, the sound, and the harbor’s parking lot for the weekend.
  • The cleanup on Monday. Volunteers get a weekend pass.
  • A small office above the chandlery, eleven months a year.

What costs nothing

  • Being in the Pool, and being found in it.
  • Writing to someone in it, by their own rules.
  • Leaving it. Nobody can pay to be shown first, and there is nothing to unlock.

The Pool costs us one file on our web server and some of Birdie’s evenings. Kindling itself charges nothing at the connection layer §1.3.

The info tent

Questions people bring to Birdie

I don’t have a page.
Any page you keep at an address will do: a short note on a site you already use, or a doc you share. The Pool points to it; we never host it, and we never copy your photos §2.5.
Someone else scanned my badge.
They saw the festival’s name and nothing else. Answering asks you to sign in with the email or account on your ticket. See what they see.
I said yes and changed my mind.
Leave from any message, or from the Pool page. It takes effect within sixty seconds §5.3, and your page stays yours.
I didn’t answer at the gate.
Your badge’s question waits 14 days §5.2. Answer at home, or let it lapse; nothing is listed either way until you say yes.
I said no. Will you ask again?
No. A no is remembered, and we cannot ask again unless you tell the Pool we may.
Who do I write to?
Birdie Novak keeps the Pool, at office@slackwaterfest.example.
