Is a driving licence required for a boat and if so how do I aquire one. I live in Pattaya, also is a registration book required and insurance as with motor vehicles. Thanks in advance. 

Yes you are supposed to have a licence even for jetskis
If you go down to the harbour master office at Bali Hai marina they should have all the info
There are also a couple of members on here who have licences. Hopefully they will elaborate.
