As with most vacations, the general rule is: the less you pack, the better. Softer luggage is ideal for stowing in cabin lockers and is generally more practical on a yacht. To help you pack, imagine what you'll be doing on your cruise. Sometimes you'll be swimming or sunbathing, sometimes you'll be eating at a great seafood restaurant. It's the type of charter and the location that determines what you should pack. Some items to consider are, light summer clothing such as shorts, tops, skirts, hats or caps, sandals, sneakers or soft-soled athletic shoes, bathing suits, and warmer nightwear such as sweatshirts, sweaters, windbreakers, jeans, and light pants. You may want to go out to dinner and meet people in the evening, so more casual and even formal clothing, such as long pants, collared shirts and perhaps a jacket, might be a good idea. If you're chartering an adventure yacht, you'll be informed of the specific items needed.
