What to bring on a cruise
Of course, a passport (valid for at least another 6 months from the date of entry to the country) with possibly. US visa (for sailing or flying through US Virgin Islands). The authorities on the other islands do not require visas from Polish, Canadian and American passport holders.
Remember that the yacht has a limited amount of space, so it's important not to pack in large rigid suitcases (there is no place on a yacht), the best solution is a soft bag that can collapse. Review your luggage a few times and ask yourself whether everything you packed will really be needed. Remember that your main outfit in the Caribbean will be shorts, a thin cotton shirt and a swimsuit. Also, remember that if you forget something, you can likely buy it in the Caribbean.
Be sure to bring a good pair of sunglasses with a lanyard, which will prolong their "possession".
Remember you will be in windy conditions, so be sure to have a hat that is attached, possibly with a cord/tie around the neck so that it won't blow away.
protective creams with sunblock:
The sun in the Caribbean is very strong, so it is absolutely necessary to wear good sunscreen with UV protection!!. After-sun lotion and anti burns can be very handy as well.
Remember to bring your prescription medications, especially those that you use every day. Be sure to bring enough of a supply, and possibly extra. Regular headache medicines, etc., can be purchased in most convenience stores in the islands.
An essential item you should pack are good shoes for walking on the yacht. They should have clear and non-slip soles. You can also walk barefoot on the deck. While exploring the islands, sandals are great as they dry quickly and are primarily airy. You can also take shoes for walking in water... Every day, light shirt (polo or T-shirt), shorts or swimsuits are worn, so take a few extras of these. Light jackets to protect from the wind is always useful. The wind, even when warm, significantly cools the body.
When going to a restaurant, you could use more clothing (long pants/light dresses) Wrap clothes in plastic bags, protecting them in this way from moisture. A thin fleece or sweater is also a good idea. Remember that you're going on a cruise in the winter months or early spring, so it can be chilly travelling from your home to your airport enroute to the Caribbean, and it is also sometimes chilly in airplanes.
During the day, there may be very short tropical rainfalls, especially at the beginning and at the end of the season. a thin raincoat is handy, and can also protect you from the wind during a night swim (if we schedule).
Take two towels, one after the bath in salty sea water and one for fresh water after taking a shower.
money and credit cards:
Check in guidebooks, which currency is used on visited island. The Virgin Islands, and French islands are cash machines and there is no problem with using credit cards. For independent islands (Dominica, St Vincent, Nevis, etc.) you might have some difficulty paying with credit cards. On most independent islands you can still pay with US dollars, and the rest is obtained in local currency (East Caribbean Dollar). Much better rate of exchange could be obtained in local banks.
On the yacht we have a CD player, which you can also connect your iPod to, so you can bring your favorite music. A guitar is on the yacht. Musical instruments are always welcome.
camera or camcorder:
It is a great idea to bring a camera or camcorder to record the cherished memories you'll make onboard and on land.
A flashlight is always on board, but a small, private one can always come in handy.
A backpack will always come in handy during excursions ashore.
What not to bring on a cruise
Bed linen (linens provided by yacht), and hair dryers and curlers. There is no is 220V, on the "Hakuna Matata" (such as at home), and the system 110V (inverter) is only suitable for charging batteries for cameras, telephones, computers or video cameras.
