Surely it must for all boat tourist operators to have checked the suitability of all tender boats with a certificate pertaining to the MAXIMUM people on board. If they do not adhere to all boating rules ,suitable life jackets with certification plus all rules which have been adopted in modern countries. I am 71 y.o now so I cannot see this transition happening. From an old rescue boatie from days gone bye. Common sense and training are a huge factor in safe boating.
