grew up in Ottawa, sailed out of chats lake ('prior!) then nepean. Latter is the best overall facility for racing/pleasure sailing. Has a very nice drysail compound with quite few cats (some tornado's still there and active...my legacy!). Club building is second to none! Lac deschenes was primarily cats but was not nearly as developed back in the 1980's when I raced out of there. Nepean will be more money but if you are a nepean resident you will get membership priority. If you need more info, my dad is still a member and can help you out.
