Hoover is a great location for sailing near Columbus.
The Hoover Sailing Club (http://www.hooversailingclub.com/
) has nice facilities but I don’t think they have a Cat Beach. They have several active monohull fleets, but I don't know any Cat guys that are there.
Additionally there is another spot further up the lake on the western shore that is a Cat Only club (Columbus Sailing Club - http://www.columbussailingclub.org/
). They have a Cat Beach and shelter house.
Lastly, there is a Public Launch (Red Bank ) facility half-way between them that does have a storage lot and a close ramp so you could store it and not have to lower the mast. I have heard there are a couple of Cat sailors that store and sail from that location, but I don’t know that from firsthand experience.
