Most people that book a 2 hour excursion tell us they wished they could sail longer. So why not start out with a 4-hour sail! You will be able to see much more of Saco Bay for sure! Also you might want to consider getting off on an uninhabited island, going for a swim, sailing outside of Saco Bay or seeing the beautiful Saco River.
There is so much to see and experience, 41hours is just what the doctor ordered! Lots of options with the large expanse of Old Orchard Beach, seeing Biddeford Pool, the 8 gorgeous islands of Saco Bay, 5 miles of the Saco River and uninhabited islands to explore!
