Tap the event, tap to claim your seat. That’s the whole thing.
A few things worth knowing:
Seats are first come, first served unless your coach runs it differently. If your crew is consistently oversubscribed, sign up as soon as the event posts.
Claiming a seat is a commitment. Your coach builds a lineup from the sign-up list. When you claim and don’t show, the boat goes out a paddler short and the balance your coach spent time on is broken. Sign up honestly and drop out early if plans change, and you’ve done the biggest single thing a paddler can do to make a season run well.
Capacity is enforced. You can’t claim seat 21 of a 20-seat event. When it’s full you’ll be offered the waitlist instead.
One seat per person per event.
