Undersea Hunter liveaboards: Argo and Sea Hunter

Argo Liveaboard in the Cocos Islands

Undersea Hunter Fleet Review

Comprising Argo and Sea Hunter, this pair of liveaboards offers diving with schools of hammerheads and other sharks in the Cocos islands in Costa Rica, and snorkelling with humpback whales at Silver Banks in the Dominican Republic. They specialise in adventure diving. The Undersea Hunter group is committed to the environment with many initiatives towards sustainability, and not just on-board ship.

Zero Speed Stabilizers dramatically reduce roll motion while anchored at Cocos Island. The inverted pyramid-shaped stabilizers are suspended on either side of the boat on outriggers and then dropped 15ft/4.5m under the water. Utilizing hydraulic power by way of a one-way valve system, the stabilizers have created a comfortable experience while living aboard the vessels. They were originally designed and implemented to support a National Geographic expedition taking place in the open ocean.
