our story


In 2007, Mike and Joanne Grandis purchased a rental house on Lake Keowee. Mike wanted to give a great vacation experience to any who came seeking one, and in the process acquired a boat for his family which he stored at the dock. Over time customers always had a question they asked him - “Can we take the boat out”? Mike decided to look at the rental scene on the lake, and realized that plenty of people wanted to be able to go out on a boat, but not deal with the hassle of maintaining and cleaning it. And so, Lake Keowee Boat Rentals was born! Over time management of the company was passed over to Mike’s son, Tyler Grandis, who currently is the general manager. Together they have catered to this community for over 10 years now, with affordable, powerful and luxurious rentals, expanding to add Jet Skis as well. We want to welcome you to our family!
