Greg Elliot who designed it called it a schooner in a "Seahorse"
article. It certainly fits the classic definition of a schooner.
Where did you read that it was a sloop? Whatever else it may be, it
is no sloop! However, there may be some confusion because they keep
separate crews for each mast and work them independently. They may
have said that running the boat was like running two sloops rather
than one schooner... But, Mari-Cha IV is a schooner.
