No streak shaming, no scores, no coaching — just a quiet record of the days you actually want to remember. - [For the trips that live in a van](https://slushbook.com/swellbook/blog/for-the-trips-that-live-in-a-van) — Why Camper Mode is the second layer Swellbook adds for surf trips that happen out of a van — parking, fresh water, toilets, distance to the line-up. - [Your first session in thirty seconds](https://slushbook.com/swellbook/blog/your-first-session-in-thirty-seconds) — What logging a surf session in Swellbook actually looks like. Only the date is required — spot, board, photos, notes are all optional. The form is shorter than the paddle out.
