It depends on when you’re sailing. Thin Tshirts, shorts, and other lightweight summer clothes are best suited for the weather from April through to September. Take a windcheater with a hood for windy days, and a few long sleeved tops. If you have sweatpants or leggings, pop some in your bags for nighttime wear. Sunglasses are an essential item in Greece. Sandals and slipons are easy to step into when going ashore and kick off when coming onboard. Bring plenty of sunscreen, ideally high SPF and waterproof. There are cool waterproof bags or drysacks you can buy in various sizes, it will keep water from getting into your expensive camera, phone, other electronics or travel documents. Space on a yacht is specialized, so soft-sided luggage is essential. Pack lightweight summer clothing, a hooded windbreaker for breezy evenings, and high-SPF waterproof sunscreen. Polarized sunglasses and non-marking deck shoes or sandals are vital for safety. We also recommend bringing a dry-sack to protect your electronics during shore transfers via dinghy.
