EXCEEDED our Expectations!

My friends and I reserved a sail with Classic Sailing for the afternoon after our flight landed in BCN. The gentle ride, fresh sea air, sunshine and cool water was just the ticket for our jet-lagged group. We would go again in a heartbeat! Everything was perfect and Captain David was a fabulous host and skipper!

Excellent!

The last week of April my boyfriend and I spent some time in Barcelona and I'm so glad I booked this for one of our days because it turned out to be one of our favorite parts of the entire trip.

Exceeded expectations. Bravo!

Way to go Dave! You and your son were such great hosts and we had a wonderful time on your boat. Dave clearly loves what he does for a living and it shows clearly. Thank you again.

Spectacular!

This was a highlight of our family visit to Barcelona. With our family of five kids, ranging from a nine year old to a twenty year old, Skipper Dave was the bomb. He answered every one of my older son's questions on the how-to and physics of sailing. We learned a lot. We also were able to stop the boat and jump into the sea for a few minutes, which was a blast. The scenery was spectacular and the boat was unbelievably cool and classic. My wife and teenage daughters loved laying on the deck and soaking in the Vitamin D. To anyone visiting Barca, I'd put this sail trip high on your list. We absolutely loved it.

All aboard for a great day sailing

Family and friends were in Barcelona for an upcoming wedding. Following days of walking and sightseeing, we enjoyed a beautiful sunny day aboard Gemini with Captain Dave. This sailing experience shows Barca in a different but beautiful light. A highlight of our trip.
