I found the company on TripAdvisor. Redline Rafting uses rafts to get small groups out to the Molokini Crater for snorkeling. If conditions are good, you get to snorkel the backside of the crater. According to what I read, the larger boats cannot go to the back side of the crater.
Trip sounds more adventurous, but possibly a little rough and check-in is at 6:30 all the way down in Kihea.
