Description






Founded in 2010 by marine biologist Ocean Ramsey and underwater photographer Juan Oliphant, charters out of Haleiwa operate under strict protocols with a 15-year 100% safety record. Every charter is led by a trained marine scientist, pairing water time alongside Galapagos, sandbar, and tiger sharks with hands-on educational briefings and behavioral tracking. The excursions center on respectful, close-up interactions designed to support ongoing marine conservation.
