Like the Aggressor boats, the Sky Dancer is part of an international chain of liveaboard dive boats -- in this case the Peter Hughes Diving fleet. In Ecuador, the Sky Dancer is administered by the very capable Ecoventura company . This modern 30m (98-ft.) vessel carries a maximum of 16 divers in eight staterooms. The air-conditioned staterooms are certainly comfortable, but I find the accommodations and amenities a notch better across the board on the two Aggressors. Still, this is a very well-run and reputable operation, and serious divers will not be disappointed here. Food and diving services are excellent, and they have top-notch facilities, including Nitrox tanks and training.
