Commercial yachts are intended to carry a maximum of 12 to 36 passengers. The number depends upon the registry, and are subject to stricter safety requirements.
This is also why a lot of yachts can only carry up to 12 guests, just because it is way easier to comply with the regulations.
Let me know if this helps!
