Hey Mathew. If you want to get in 3 dives on a boat that Sunday just sign up solo. All the boats are really good about asking who needs a buddy and then pairing people up. That’s how I started meeting new people when I first started diving. I don’t know about all the boats, but I know some of them will include tanks and weights so you don’t need to bring anything. I believe the Pacific Star offers that if you request when you sign up.
