Do I need to bring a dive buddy?

No — every dive is led by a divemaster who handles buddy assignments. Solo divers are paired with other solo divers or with experienced groups who welcome a third buddy.

Buddy assignments are usually flexible — you may have a different buddy for every dive, or you may stick with the same person all week if you click with them. The cruise director and divemasters watch the group dynamics and quietly intervene if anyone seems to be struggling or being left out.

Solo diving (no buddy) is becoming more common on premium boats and expedition trips. Some operators allow it if you have a Solo Diver / Self-Reliant Diver certification (PADI Self-Reliant Diver or SDI Solo Diver) plus a redundant air source (pony bottle or twin set). Galápagos, Cocos and Socorro operators sometimes allow this for advanced divers; Maldives and Caribbean operators typically don't.

If you're traveling solo and worried about being a burden on other divers, don't be. Most experienced divers actively welcome a third buddy — it adds variety to the dive, and many groups appreciate the help if someone needs assistance with their gear or has an issue underwater. The dive guide also takes responsibility for you, so you're never truly alone.

Tip: introduce yourself to the divemaster and other guests on the welcome night and mention you're solo. By the second dive you'll have a friend you can dive with consistently.
