from around the world to Bonaire. The shallow Bay is on the windward side of the island, so trade winds are strong and constant. A barrier reef across the mouth of the bay allows windsurfers of all skill levels to select wave conditions they like. Lac Bay is one of the stops in the PWA Windsurfing Freestyle World Cup and has hosted the Prokids IFCA Championship. Five of the PWA's ten highest ranked freestyle windsurfers are from Bonaire: Kiri Thode, Amado Vrieswijk, Bjorn Saragoza, Tonky Frans and Taty Frans. In the northern end of Lac Bay is one of the best preserved mangrove forests in the Caribbean, which is popular for kayaking and snorkelling. Bonaire is also a port of call for more than fifteen cruise lines who make more than eighty calls per season at the island. The total passenger capacity for cruise ships in Bonaire is about 185,000. Tourism infrastructure in Bonaire is contemporary and offers a variety of types of accommodations including hotels, full-service resorts, a few small bed and breakfasts and self-catering vacation rentals of all kinds. Other tourist activities include kite-boarding, windsurfing, mountain-biking, hiking, sailing, charter fishing, boating and bird-watching. All-in-all tourist expenditures in Bonaire are estimated at $125 million per year.

The decision was based primarily on the needs for tourism and trade. Most countries and territories in the Caribbean use the dollar as their currency or have a currency linked to the dollar as legal tender. The guilder was pegged to the US dollar for decades with an exchange rate of ƒ1.79 = US$1.00. Adopting the dollar put an end to the dual-currency payment system and foreign exchange charges. The guilder remained in use in Curaçao and Sint Maarten. Taxes The separate tax regimes for Bonaire, St Eustatius and Saba present a greater risk of double taxation or double exemption from taxes. In an effort to remove the risk, two plans were introduced. One plan prevents double taxation between the Netherlands (Europe) and the BES Islands while the other prevents double taxation between the BES Islands and third countries. The new regime will generate a total annual tax revenue estimated at $52 million which is equal to the
