ScubaDock is not a booking system, and it does not embed FareHarbor's calendar or Lightframe. Each course and each trip has its own booking link in the builder. You can paste a FareHarbor URL, or any other https booking page.
When you paste your current site, ScubaDock looks for FareHarbor links on the public pages and can attach the first one it finds to the first course or trip. You review that, then add a link on every course and trip that should book online.
On a published site, a course or trip with a link shows a Continue to booking button. The button opens the link in a new tab. ScubaDock counts the click. The diver pays on FareHarbor, not here.
If a course or trip has no booking link, the page sends the diver to the shop's contact page instead. The contact page can also show a WhatsApp button, once you add the shop number, and an inquiry form after you publish.
