In the SE (SC, NC, GA) most of our regattas are run out of clubs (Lake Norman, Keowee, Lanier, Columbia, James Island (Charleston), Pee Dee) and these clubs are friendly to catamarans. Most of us belong to one of these clubs in some fashion or another. Only a few regattas (Myrtle Beach, Spring Fever) are run without club affiliation. Most of us do not utilize the mast up storage because we are still so nomadic in traveling to the other clubs, we keep our boats at home but probably 20% of us do own other boats (monohulls) that we do keep at the clubs.
