The service and boat provided were excellent. The guys were friendly and laid-back. The boats were in great condition. If you've never sailed before, the guys will give you an introduction to operating a boat, and honestly, it becomes really easy after just 10 minutes. Most people sail up to Kassiopi for coffee and then make stops at various places on the way back. The cost for renting a beginner's boat is 90 euros, which is more than enough, considering the additional cost of petrol. We went to Kassiopi and made stops at two places, maintaining a steady pace and spending 20 euros on fuel. Docking at the stops can be a challenge, but the local guys are always there to help you out. In fact, one guy even jumped in and parked the boat for us.
