qué llevar para un día en barco

What to bring for a full day on a boat

Jul 28, 2026 | News

Spending a day at sea is one of the best ways to enjoy the summer, discover the coastline from a different perspective and reach beautiful coves that may be difficult to access from land. However, preparing properly is essential if you want the experience to be comfortable and stress-free.

Planning a trip with OnBoats from L’Ametlla de Mar? Use this checklist to make sure you have everything you need for a memorable day on the Mediterranean.

Reliable sun protection

Sun exposure can be particularly intense at sea because sunlight reflects off the water. Bring high-factor, water-resistant sunscreen and apply it before boarding the boat. Remember to reapply it regularly throughout the day, especially after swimming.

Sunglasses with UV protection, a cap or hat and a lightweight shirt are also highly recommended. Covering your shoulders during the sunniest part of the day can help protect your skin and keep you comfortable.

Comfortable and practical clothing

Choose lightweight, breathable clothing that allows you to move easily around the boat. Swimwear is essential, but you should also pack a spare T-shirt and a light outer layer.

Even during the summer, it can feel cooler when the boat is moving or when the wind picks up. A thin jacket or windbreaker takes up very little room and can be useful in the morning or towards the end of the day.

Wear comfortable, non-slip shoes that can get wet. Avoid heels and footwear with hard or slippery soles.

Enough water and easy-to-eat food

Staying hydrated is extremely important during a full day on a boat. Bring enough drinking water for everyone in your group and avoid relying only on soft drinks or alcoholic beverages.

Pack food that is light, fresh and easy to handle, such as fruit, sandwiches, cold salads, nuts and snacks. Reusable containers will make everything easier to organise, while a cooler can help keep food and drinks fresh.

Try to avoid very heavy meals, particularly if you or someone in your group is prone to seasickness.

A towel and swimming accessories

A quick-drying towel is ideal because it takes up less space and is easy to reuse throughout the day. You may also want to bring a mask, snorkel or waterproof camera for swimming stops.

Before packing additional equipment, check what is already included with your OnBoats rental. This will help you avoid carrying unnecessary items.

A waterproof bag for personal belongings

Phones, wallets, keys and documents should be protected from water and splashes. Store them in a waterproof bag or individual waterproof cases.

Only bring the valuables you genuinely need. You should also carry identification and, when renting a boat without a skipper, the appropriate boating licence or qualification.

Seasickness preparation and personal medication

Anyone who is sensitive to motion should prepare before departure. Bring the seasickness remedy you normally use and seek professional medical advice when necessary.

Eating a light breakfast, staying hydrated, getting fresh air and looking towards the horizon can also help reduce discomfort.

Any personal medication should be stored somewhere dry, shaded and easily accessible.

A bag for rubbish

Everything you take on board should return to land with you. Bring a separate bag for food packaging, bottles and other rubbish generated during the day.

Protecting the marine environment is everyone’s responsibility, so never throw waste into the sea or leave it behind in a cove.

Packing carefully means you can focus on what really matters: swimming, relaxing, exploring the coastline and enjoying a special day with your friends or family.

With OnBoats, you can plan a boating experience that suits your group and discover the Mediterranean coast around L’Ametlla de Mar from a completely different point of view. During the busiest summer months, booking in advance is recommended to secure your preferred date and boat.
