This is claimed to be the biggest passenger carrying Rib in Europe. I have no idea if it is - its one of the Dolphin watch boats operating out of Lagos Marina, Portugal.
Its around 13m in length - and has twin 350hp engines (from memory) with waterjet drives.
Quite an impressive beast! And the lads that operate the service are a great bunch of guys too. Mind you they dont worry too much about things like lifejackets out here as you can see.
