Feature
Instructor Scheduling Without the Group Chat
Thalassa schedules sessions and staff together. Assign a lead and assistant instructor to every session, and let the system catch clashes before your team finds them at the dock.
The problem
Shared spreadsheets don’t say no
Two people edit the schedule and the same instructor ends up on two sessions.
A session was booked, but nobody assigned an instructor to it.
One instructor has eight students in the water because the group grew overnight.
Two sessions are booked in the same pool lane at the same time.
Staffing
Lead and assistant instructors on every session
Assign one or more instructors to a session and mark each as lead or assistant. Each session also carries its location, meeting point, time, duration and maximum number of participants.
- Lead and assistant roles
- Location and meeting point
- Duration and capacity per session
- Theory, pool, open water, debrief or custom session types
Clash protection
Conflicts caught before they happen
When you schedule or reschedule a session, Thalassa checks it against everything else on the calendar.
- Blocked: an instructor already on an overlapping session
- Warning: more than four students per instructor
- Warning: another session at the same location and time
Daily view
Today, tomorrow and what’s still unscheduled
The dashboard shows today’s sessions with their instructors and student counts, the next few days, and every booking that still has sessions to schedule. Filter the sessions list by status, type, location or instructor.

After the session
Attendance and sign-off
Instructors mark each participant present, absent or late cancel, and the session is completed by a named team member with a timestamp. Attendance updates every student’s course ledger automatically.
- Attendance per participant
- Completed by and completed at
- Session expenses such as boat fuel or pool hire

The ratio warning follows a common open water guideline. Tell us about your own standards on the demo.
Does it handle instructor availability or days off?
