Comfort
If you haven’t spent a lot of time chartering boats, especially internationally, a flotilla gives you a little piece of mind. You’re not alone. There are like-minded people coming along with you and you know that the trip is planned. Any troubleshooting can be done by multiple people and you have the added security of having other sailors nearby. There’s often a local skipper (always, for our trips) in the group, so you have a built-in tour guide as well.
