In the 26 February 2009 edition of the San Pedro Sun, the Caye Caulker Water Taxi Association has an advertisement announcing a new schedule effective 1 March 2009, and a joining of services with Triple J Water Taxi.

Don't know if the schedules on their website have been updated.

In the same issue of the Sun, there was another advertisement regarding another water taxi service, SAN PEDRO BELIZE EXPRESS WATER TAXI. This ad, with schedules, can viewed after downloading the pdf version of the paper from the newspaper's website.

There's also a web site for San Pedro - Belize Express water taxi service, which includes both the San Pedro-Belize City and San Pedro-Corozal Town trips: http://www.sanpedrowatertaxi.com/files/schedule.html
