Tarn for tubing & float trips

Tubing and float trip booking software for high-volume summers.

Hundreds of floaters on a hot Saturday, launch windows to fill, and a waiver for every single tube. Tarn keeps the line moving.

Float operations are a volume game: launch windows instead of guided departures, price points low enough that booking friction is fatal, and summer Saturdays where the parking lot decides whether the day was good. Tarn sells your launch windows against live capacity on your own website, gets waivers signed from phones before groups arrive, and gives the crew at the water's edge a manifest that shows who's paid and who's signed, so peak-day check-in is a glance, not a pile of clipboards.

Built for how you run

The parts of your day Tarn already knows.

Launch windows, sold to capacity

Set your launch times and how many floaters each can take. The widget sells against live counts all day, so the 11:00 window closes itself when it's full.

Waivers at Saturday scale

Every booking's waiver link goes out at confirmation and reminders chase the stragglers. On a 400-floater day, that's the difference between clipboards and a glance at the manifest.

Groups that organize themselves

The reunion books once, gets a group payment link, and every family pays its own share. The organizer stops being your collections department.

The river you float, on the dashboard

Current flow from your USGS gauge and the day's forecast sit next to the booking calendar: the factual readings behind your morning go/no-go call.

Your website, your Stripe account

The booking widget embeds on the site you already own, payments run through your own Stripe account with payouts straight to your bank, and every booking, contact, and waiver exports anytime.

Pay only when you're running

No monthly fee and no contract. Tarn takes a published 3% per booking, stepping down to 2% as you grow, and a closed season costs you $0.

Common questions

Can Tarn handle a 400-person Saturday?

Yes. Capacity is tracked per launch window in real time, bookings land instantly on the calendar, and the manifest scales to however many floaters you put on the water.

Do walk-ups and phone bookings count against capacity?

Yes. Bookings your crew enters at the counter come out of the same live counts the website sells against, so the window can't oversell.

We're only open four months a year. What do we pay the other eight?

Nothing. No monthly fee, no contract. Tarn charges a published percentage per booking, so the closed season costs $0.

Your next season starts at the desk. Make it a short visit.

Set up your trips, take your first booking, and get back to the river.
