What’s the Maximum Passenger Limit on Longtail Boat?

I just saw on Channel 39 a longtail with 16 passengers (at least – I couldn’t count them all as fast as I needed to) and 2 staff.

It was a segment about whether the red shirt rally was going to affect tourism.

Does anyone know – how many passengers on a longtail? Are there different size longtails with different passenger limits?

Just wondering… I’ve always been told no more than 6 passengers I think it is.
