Boka Bay tour out of Kotor, with pick up at Huma Hotel at Dodrota & then first to Our Lady of the Rocks chapel which is a "must do'" ... 25 minutes is ample time.
Then power down other arm of Boka Bay , next stop the Submarine pods which are interesting, then out to the Adriatic & past Mamula Fortress & its twin forts nearby.
The Blue Grotto is fun as we dropped into the water & swam around. You can't quite recall such lovely clear waters ... but it is fairly open sea so be aware of the swell.
Back on board we power off past Tivat & around into the reach of Boka Bay & are deposited back to Huma Hotel jetty ... the rest of the group then head to Kotor.
A good morning, fortunately fine sunny weather.
Igor the pilot, was not that informative, but over the motors of the speed boat little conversation is going to be heard. A basic facts sheet to hand out would be a good option.
