Breathtaking!

This sailing trip 4-5 miles from the coast of the city was most probably the highlight of our trip.

Fantastic experience

My wife and I recently had the pleasure of sailing with Dave on the Gemini. It was an unforgettable experience. Dave is a pleasure personally and a very professional skipper. The boat is beautiful as well. He stopped twice so we could have a swim. He provides water but if you want anything else to drink or eat you gotta bring it. If you are thinking about sailing in Barcelona.. don't hesitate. Book with Dave and you wont be disappointed!

Lovely way to spend a couple of hours

Our group of 11, including 6 children aged 9-12, had a wonderful trip. Captain Danny was very friendly and let all the kids have a go at skippering the boat, which was one of their highlights of visiting Barcelona!

A sunset sail with David!

After a long day of walking the streets of Barcelona, our group of 8 (seniors) took a cab to meet David for his last sail of the day. Unfortunately for David, his classic sail boat was down for repairs, however; he had a backup plan in place when we arrived. We spent a relaxing evening enjoying our wine and snacks while sailing in a 42' sailboat overlooking the magnificent city of Barcelona. Seeing the sunset over the water...priceless! The best advise I can offer is to book a sail with David. David is a first class captain and we (really) enjoyed his company. David was not only easy on the eyes, he was a delightful captain to talk to. David left nothing unanswered if you had a question about sailing or the city of Barcelona. What an enjoyable evening...thank you David for adding your personal touch to a beautiful evening! You're the best and we wish you much success!!!

Unwind with wind!!

Just had our honeymoon in Barcelona, it's an amazing city with plenty to eat, drink and see, after a fantastic week of trying to do as much as possible we could not have found a better way to relax and chill out than our trip with Dave on Gemini. We took the sunset cruise and it was just the two of us, Dave is really friendly and made our evening very relaxed, perfect way to end our honeymoon. He is also very knowledgeable about Barcelona too. Can't recommend it enough.

Could not have had a better first-time sailing experience

This was a weekend of firsts - first time in Barcelona, first time on a sailboat, first time on the Mediterranean. Skipper Dave's sailing cruise operation is as skillful as it is courteous. Whether you're into talking about the techniques and history of sailing or just sitting back and enjoying the views and sounds of sailing off the coast at Barcelona this is an experience worth every Euro.
