Highly recommended experience

Highly recommended activity in Barcelona! It was amazing to enjoy the sailing, sun, sea while chilling on the deck of the classic yacht and chatting with friends, enjoying drinks and even jumping for a swim.

Great way to see Barcelona

Fab way to get away from it all and see Barcelona from another perspective. Lovely historic boat. Kids are most welcome!

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.

Amazing afternoon

My sister and I spent an afternoon on Dave's boat and it was one of the best things we did on our trip. The views are amazing, the boat is beautiful and Dave is a great captain. The views from the ocean are incredible and really lets you see Barcelona from another perspective. We were able to bring lunch and cava and just lay in the quiet sun for a few hours. We were originally scheduled for a Monday but the weather was bad so Dave was very accommodating in rescheduling with us. Would definitely recommend!

Fantastic day of sailing!

What a great experience! We went sailing with Dave in early April for my birthday. Dave is fantastic and Gemini is gorgeous! Seeing Barcelona from sea was gorgeous. Can't recommend doing this enough!
