Open water sessions on a boat trip

Open water sessions are dives, so they happen on boat trips. Assigning a session to a trip creates a dive group for the course on that trip.

Assign a session to a trip

On the course's Sessions tab, press Assign to boat trip on an open water session:

1. Search the upcoming trips of the next 90 days, or press New trip to plan one without leaving the dialog.
2. Set the Dive group name; it defaults to the session name.
3. Optionally choose an Instructor for this session only; the list only offers staff who may teach. Otherwise the course instructor leads, unless an earlier assignment already gave this session its own instructor.
4. Press Assign to trip.

The session takes the trip's date when it is assigned, and moves along when the trip is later moved to another date; that move is refused while the session's instructor is busy at the new time. A dive group with the course's students is created on the trip, sized by the course's Max students, or for 4 divers when the course has no limit. If there are more students than places, the assignment is refused. It is also refused if the instructor who leads already has another trip, a course session, a duty or time off at that time. Two sessions of the same course on the same trip share one group.

On the trip

The group carries a course badge that links back to the course. Students cannot be removed from the group on the trip page; instead Mark absent for this session records the absence and takes the student off the group, unless they are still pending or present on another session that shares it. A student who is withdrawn from the course leaves the groups on trips dated today or later by themselves, and removing an enrolment removes its seats. On the trip, the waiver check covers the students like everyone else, against the waivers required for everyone or for courses, their course template's Additional waivers and the group's extra waivers, while the certification check leaves them out, because enrolment already checked the course prerequisite; see Waiver expiry, renewal and checks.

Unassign

Unassign from boat trip detaches the session. The group leaves the trip unless another session of the course still uses it. This is refused from the day after the session date, or once a student was already marked present.

Cancelling the course

Cancelling a course takes its groups off every trip dated today or later. Trips on earlier dates keep the group for the records.

Students enrolled later

A student enrolled after the sessions were assigned is added to the existing dive groups. If a group is already full, the enrolment fails with a message, so set or raise the course's student limit first. Online, the booking page counts this too: a course whose open water dive group is full is not offered until the group has room.
