Pre-registration is the norm at CRAW - and there is a regatta discount to encourage that. And speaking for myself I find it much more convenient to be able to use paypal from home than worry about paying at the regatta site. And I like to see who else is coming too.

However, I would say attendance at CRAW regattas is pretty strong and fairly consistent from event to event, which I put down to two things - (i) events are not so frequent that people would want to miss one - with so much invested in our boats and with the season being relatively constrained I think people are strongly motivated to show up, and (ii) the friendships in the group are well-established and strong, and people are very friendly towards newcomers, which again I think creates positive motivation towards attendance.
