Walking tours can sometimes be brief. People might only spend around a half an hour on certain tours. The people who take boat tours will usually want something slightly more substantial. There are multiple boat tours that will last for about an hour and a half. The people on these tours will have enough time to really get a glimpse of everything when they take these tours. 

It already takes some time to get everyone in the boat in the first place. If the actual tour only lasts for a half an hour, or even a full hour, people may end up remembering the boat boarding process more than the actual tour.

When organizations like the Manatee offer tours that are slightly longer than that, people can already feel as if they have really gotten the benefits of the boat ride itself, along with whatever they were actually able to see when they were there.

These are the sorts of tours that will give people the chance to take lots of pictures on their phones or other devices. Visitors on the tours will have lots of memories connected to them at different points, and they won’t feel as if they were stuck on the boat at any point.
