Rotarians are a gregarious bunch. Not only do they gather together for weekly meetings, “making up” at the meetings of other clubs when they can’t attend meetings of their home club, and participate together in club projects, they also form other associations based on specific interests. The Rotary Fellowships page at the Rotary International website lists 113 fellowships, from Amateur Radio to Yachting (more about that in a minute). Another page provides more information on these fellowships along with instructions for starting a new one. There are also links to a flier about the fellowships and the official fellowships handbook.
Membership in Rotary fellowships is open to Rotarians, Rotaractors, Rotary program participants and alumni, and their spouses.
The largest fellowship in Rotary is the Rotary Global History Fellowship. Its website is a gigantic sprawling one, but it does provide a one-page potted history of Rotary. Even without joining the fellowship, you can get a free subscription to its newsletter.
There are currently chapters of at least two Rotary Fellowships in District 6880. One is the International Fellowship of Scouting Rotarians.
The other is the Mobile Bay Compass Rose Fleet of the International Yachting Fellowship of Rotarians. You need not own a boat to belong to IYFR: “International Fellowship of Yachting Rotarians members combine an acceptance of the principles of Rotary with a love of boats, sea, rivers, & inland waters.”
