Customs adds further complications, and advance research is required. You may need an agent, or advance paperwork to avoid delays and fees or fines. Many countries, but far from all, facilitate “yacht-in-transit” deliveries without charging duty.

On the other hand, we got to try a great new food dive and met some interesting people along the way to duty-free importing.
