What to Pack for a Positano to Capri Boat Day

What is already on board, so you can stop packing it

Several operators on this coast publish what they include on board. One skipper's checklist for private boat days lists towels, snorkelling masks, fresh water, soft drinks, beer, a welcome prosecco, shade under the bimini top, and USB charging for phones, so duplicating these items just adds weight to your bag.

A group departure from Positano to Capri also lists beach towels, water and soft drinks, a glass of prosecco, and a swim and snorkel stop as included. If you book with a different operator, the day before departure is the moment to check that list directly with them. Assuming towels or masks are provided when they are not is the most common way to end up uncomfortable.

A compact packable towel is the one exception worth carrying if you plan to swim again after you leave the boat. It weighs very little when compressed and doubles as a seat cover on hot stone. An inflatable neck pillow costs more space than it saves on a day trip.

The base layer: swimsuit under light clothing

Wearing your swimsuit under a looser top or dress is the practical solution for a day with swim stops and a landing in Capri. You change nowhere, you stay cool, and you are ready the moment the captain anchors in a bay. Choose a suit that stays put when you move rather than one that needs constant adjusting.

Over it, a breathable linen or cotton cover-up, or a light unbuttoned shirt, gives you sun cover between swims without bulk. Linen and cotton move air while you sit in the sun, and they dry faster than heavy blends. A long cotton or linen shirt also works over a suit at lunch without looking like you forgot to dress.

If rain is possible in the days around your trip, a compact rain shell is worth adding to the bag, but it should fold to the size of your fist so it does not crowd out towel space. A heavier waterproof layer stays home.

Barefoot on deck: plan shoes only for landing

On many boats on this coast, the deck is a barefoot zone, partly to protect the teak and partly for grip and safety. That means your shoes spend almost the whole crossing in your bag. Pack flat, easy to slip on and off, and comfortable enough that you barely notice them when you do put them on.

For going ashore, comfortable sandals or trainers both work; the choice comes down to the day's plan. Capri's lanes reward a sole with grip, while Positano's stairways favour a shoe you can tighten. Leave heels at the hotel, because they fail on both surfaces and are the one item that never pays for itself in bag space.

Flip-flops are useful for rocky beaches and the swim stop, but they are not enough for Capri's steep lanes. A pair of sandals that can be rinsed under a tap after saltwater and a lighter pair for the boat is a workable compromise. One pair of shoes per job beats three pairs that half-work, and the full range of options is set out in the guide to what shoes to wear in Positano.

Footwear trade-offs: lanes, steps and rocky beaches

Positano is a town of stairways, and Capri's walk from the port up to the Piazzetta climbs steadily. Both places punish flat-soled fashion sandals over a full day. A shoe with a treaded sole and a secure strap is the single best upgrade to your bag for this trip.

Rocky beaches rather than sand are the norm along this coast, so feet can heat quickly between the water's edge and your towel. Rinseable sandals you can wear into the shallows and shake dry after are more useful than a second pair of sneakers. If you plan to swim off the boat rather than from a beach, water shoes are unnecessary.

Whichever pair you choose, wear it on the way to the boat rather than packing it. That removes a pair from your bag entirely and leaves your hands free on boarding.

Sun protection at sea: the item people underestimate

Reflection off the water roughly doubles your sun exposure compared with standing on land, and on a boat there is nowhere to step out of it for long. High-SPF sunscreen, sunglasses and a hat belong in the bag every time, not just in high summer, and sunscreen needs reapplying after every swim.

A hat with a chin cord stays on in wind that a loose hat will not survive, and polarised sunglasses cut glare off the water noticeably. Lip balm with sun protection is easy to forget and easy to need by mid-afternoon on deck. A light long-sleeve shirt provides simpler, more even cover than reapplying cream to your shoulders every hour.

Sun cream, a swimsuit and a hat are the three items one group operator from Positano tells guests to bring; everything else on their checklist concerns comfort rather than necessity. Build the bag around those three and the rest falls into place.

One slightly smarter layer for lunch in Capri or Positano

If you plan a long lunch on Capri or back in Positano, one smarter layer makes the transition from swim stop to table easier. Linen works well here: it looks considered but moves air, and it handles sea humidity better than a heavy fabric.

For that layer, think a light button-down shirt in linen, a simple dress, or a clean pair of trousers with a tucked-in tee. A skipper's checklist suggests something slightly smarter for a long lunch in Capri or Positano, but this is an editorial suggestion rather than a universal rule. If a particular restaurant matters to your day, check its own guidance directly.

The same dress or shirt can also work for an evening drink after you land, which keeps your bag to a single outfit change for the day.

Layers for the ride home: spring and autumn can turn breezy

Warm days on this coast can end with a breezy return leg, especially in spring and autumn. One charter operator advises a light jacket for exactly this reason, and it costs little space in the bag. If you feel the cold easily, take a thin windproof shell rather than a bulky knit.

If your trip falls in a shoulder season, checking local conditions before you go helps you pick the right outer layer. Our guide to what to wear in Positano in November sets out how the coastal season shifts and what visitors typically wear as the weather cools.

A scarf doubles as a layer for your neck, a wrap if the wind picks up, and something to sit on if the deck is damp, which is more useful in a small bag than a second jumper.

Wet-swimwear and dry-bag logic

A spare swimsuit and a quick-drying microfibre towel are the two items that make a day with multiple swim stops workable, and both appear on a published boat-day packing list for this coast. Changing into a dry suit after the last swim keeps the return leg pleasant, and a microfibre towel takes a fraction of the space of a regular beach towel.

A dry bag or a simple waterproof pouch solves the phone problem, since swim-stop photos are the most common way phones end up wet. One charter operator notes that boats have dry storage for bags along with USB charging, while still suggesting a waterproof pouch as a useful extra for swim-stop photos.

Before you pack anything wet for the return to the hotel, wring it out and put it in a separate bag so the rest of your clothes stay dry on the walk back up the steps.

Small cash for the extras ashore, and what stays in the hotel safe

Cards work almost everywhere ashore, but a little cash in small notes makes three things easier: the rowing boats that enter the Blue Grotto, a sunbed at a beach club, and a gelato on the Marina. A group operator from Positano explains that entry to the Blue Grotto depends on weather and sea conditions, that the rowing boats are run by the Cooperativa Battellieri di Capri, and that tickets are bought on site. If you want the current entry price, ask on the day rather than relying on any figure quoted online.

Meanwhile the hotel safe is where your passport, spare cards and any jewellery should stay, which is what one charter operator recommends for passports and serious valuables. These are exactly the things that are hard to replace. Carry just one card, a copy of your ID and enough cash for the day in a small waterproof pouch.

A compact packing example for one boat day from Positano

A single day from Positano to Capri reduces to a small list: the swimsuit you are wearing, one light cover-up or shirt, one slightly smarter layer for lunch, a light jacket, a spare swimsuit, a microfibre towel, a waterproof phone pouch, small cash, sunglasses, a hat and sunscreen. Add one pair of sandals or trainers for stepping ashore and a spare pair of flip-flops for rocky beaches, and the bag is complete.

Everything already listed as on board, from towels to snorkel masks, stays behind. That is where the weight disappears: the bag you carry to the pier ends up being little more than a towel, a layer and a pouch.

If your trip falls in a shoulder month, running the same list against what to wear in Positano in May helps you gauge how much outer layer to add without overpacking.

What to leave behind

Passports, spare cards and valuables stay in the hotel safe, along with any jewellery you would hate to lose in the water, following the same logic that one charter operator applies to passports and serious valuables. Heels stay at the hotel too, since the barefoot deck and the cobbles of Capri and Positano are no place for them.

Serious camera equipment is another category worth reconsidering. A phone in a waterproof pouch handles almost all of a boat day's photography, and a heavy camera body adds weight and a constant worry about spray.

Before you leave: check the marine forecast and adjust layers, not the bag

Wind and sea state change what feels comfortable more than temperature alone. Check the marine forecast for the day before you pack the final layer and decide whether the light jacket comes, and remember that the captain can change the itinerary depending on winds and currents. Look at the forecast the morning of departure rather than the week before.

If you are prone to seasickness, it is worth preparing in advance and letting the skipper know so he can favour the sheltered side of the coast, which is what a skipper's checklist recommends. On a calm day along this stretch, most travellers feel nothing. Beyond that, the skipper is the person to consult rather than a fixed rule from an article.

Whatever the forecast says, add nothing to the bag except the layer you actually need. That is the core of packing light for a boat day from Positano to Capri.

Pack Light, Land Ready

A boat day from Positano to Capri works best with a small bag: swimwear worn under breathable layers, sun protection you can reapply, one slightly smarter layer for lunch, a dry option for the return, and shoes for landing rather than for the deck. Everything already supplied on board stays at the hotel.

Checking the marine forecast on the morning of your trip, and confirming with your operator what is included, is the last step before you walk to the pier. Beyond that, the day takes care of itself.
