THERAPY-IV provides plenty of flexible options to enjoy a deep sea fishing boat experience with friends, family, or colleagues. Choose from a half-day or full day charter, the former lasting about four hours. Full day charters usually include multiple fishing locations which increase the odds of catching different types of fish such as the amberjack, blue marlin, hammerhead shark, snapper, wahoo, and more. There is also the option of private charters which provide a more intimate fishing experience.
