I found Jacinta and Luigi while looking for a day boat trip along the Amalfi coast. I am so happy that I did. We spent a day on the boat with Luigi cursing up and down the coast - it was the best day of our 2.5 week Italian adventure and worth every single euro!!!!
We met Luigi at the dock in the morning (Jacinta wasn't able to join us) - he welcomed my husband and I aboard his beautiful boat. We stretched out on the front and enjoyed the scenery along with all of his stories and explanations of various sites. We stopped for a few swims - Luigi was on watch the whole time for jelly fish so we wouldn't get stung! Lunch was at an amazing waterfront restaurant - one of the best meals we had -- zucchini pasta, peach wine, and antipasto.
You can tailor the trip to your preferences -- we didn't visit any grottos or stop much - but if you have specific wishes Luigi will be happy to accommodate. Luigi set us up with his friend who does kayak tours for the next day (Windsurfpraiano - see review).
I only wish I had found them before booking our accommodations and planning much of the trip. When I return I'll leave all the planning to Jacinta and Luigi!!
