My wife and I took the "Cuise Like A Local" tour with Sea Sydney Cruises back on November 25, 2013. If you want to escape the tourists traps, and want a private, relaxing tour with no more than 12 people on the yacht, then this is the tour to go on. It really doesn't even seem right calling it a "tour". You literally feel like it's your yacht for the affternoon since it's such a good size yacht (52 feet, I believe) and there is plenty of room for folks to move around and enjoy the day.
The pictures and the past reviews hit the nail on the head. It is a relaxing cruise with very informative and helpful deck hands. Alex is very personable and the meal is a true Australian feast. Beer, wine, and all drinks are unlimited. Bring your bathing suit even if you think you may not go swimming. We went in November as mentioned, and we were fortunate to have a very warm spring/early summer day. The water was cool, but it was worth the dip. Refreshing and a lot of fun. There were folks swimming off the beaches, so I knew I wasn't that crazy to go in. Thoroughly enjoyed it.
All in all. it's a great way to see Sydney and some areas of Sydney you may not get a chance to see from the water's view point. Also, if you are touring around the city (or Australia in general), this tour gives you a nice break from the hustle and bustle of playing "tourist". Great relaxing afternoon. We'll do it again some day when we get back to Australia. Thanks to the captain and crew for a great afternoon. Cheers!
