Anka's crew of seven are Greek, warm and gracious. The stews chatted with guests as they refilled drinks and brought out plates of warm appetizers. As the afternoon sun gained height, some of us headed down to the beach club, changed into wetsuits and jumped in the water. Anka has a flotilla of water toys, including two Sea-Doos, stand-up paddleboards, scuba equipment, and a Williams jet tender powerful enough to pull water-skiers. For me, the must-have machines were the Seabobs, battery-powered water toys that pull a person either along the water's surface or down into its depths. We spent a few hours letting the Seabobs pull us back and forth between the yacht and the clear shoals below.
