Sailing -- Sailing excursions are offered by many charter groups, most notably Sail Provo (tel. 649/946-4783; www.sailprovo.com/contact.htm). It sails 14m or 15m (48-ft. or 52-ft.) catamarans on half- or full-day excursions. One of the most frequented is a sailing and snorkeling trip for $63 (£32) that's offered on Monday, Wednesday, and Saturday and includes a tour of Little Water Cay, or "Iguana Island." A full-day cruise Tuesday to Friday costs $124 (£62), including a lunch buffet served onboard. Sail Provo also offers sunset cruises and glowworm cruises.
A retired rumrunner, Atabeyra, is owned by Sun Charters (tel. 649/231-0624; www.suncharters.tc). Happy hour sunset cruises cost $39 (£20) per person. Customized private charters can be arranged for half- or full-day trips and include food, drinks, snorkeling gear, and sailing down the chain of Caicos Cays, perhaps following an ocean trail blazed by Columbus. A kid-pleasing 3-hour Pirate Cruise goes to Treasure Island and costs $49 to $59 (£25-£30).
You can also sail aboard the catamaran Beluga (tel. 649/946-4396; www.sailbeluga.com) where Captain Tim Ainley leads small, personally tailored beach excursions or private charters for romantic beach barbecues.
Parasailing -- You won't see jet skis blazing across Grace Bay, but you will see the occasional billowy parasail high up in the air, casting shadows on the aquamarine seas. Your best bet is to call on Captain Marvin's Parasailing, Grace Bay (tel. 649/231-0643; www.captainmarvinsparasail.com). A 15-minute flight over beautiful Grace Bay costs $75 (£38). You can also take a banana-boat ride at $25 per person or go water-skiing for $275 (£138) per hour ($250/£125 per hour for more than 1 hr.).
Windsurfing & Kite-Boarding -- You can get kite-boarding and windsurfing lessons and/or equipment rentals at Windsurfing Provo on the Beach (Seven Stars Resort, Grace Bay, Providenciales; tel. 649/941-1687; www.windsurfingprovo.tc). You can also rent kayaks and boogie boards here.
