Location and Destination Guide

Usually this boat operates around Sag Harbor, NY.

New York City looks great from the ground, but that view from the water is something else! Jump aboard a Sailo boat rental from the Big Apple and experience the thrill of the sea - and snap plenty of incredible pictures. Sailing in NYC is a must on your summer bucket list, whether you are visiting or a New Yorker.

It might not be the first thing you think of when finding things to do in New York City, but renting a boat for a full day or just a few hours is a truly memorable experience.
