Packing for a liveaboard trip is different from packing for a resort holiday. Space is limited, laundry options are minimal, and you will spend most of your time either diving or relaxing between dives. Getting your packing list right means you bring everything you need without overloading your luggage.
Here is what we recommend based on years of Red Sea liveaboard experience — including a few items that first-timers often forget.
Dive Gear Essentials
Start with what matters most. These are the items that affect your safety and comfort underwater.
Exposure protection. The Red Sea is warm, but water temperature varies by season. From June to September, a 3mm wetsuit or even a rashguard is enough for most divers. From October to May, bring a 5mm wetsuit — water temperatures drop to around 22°C in the deeper sites, and you will feel it on your third or fourth dive of the day. A hooded vest is a versatile add-on that packs small and makes a real difference on deeper dives.
Mask and fins. Always bring your own. Rental masks rarely fit as well as your own, and a leaking mask ruins a dive faster than anything else. If you wear prescription lenses, this is non-negotiable. Fins should be comfortable for multiple dives per day — blisters from ill-fitting rental fins are a common liveaboard complaint.
Dive computer. Your own computer tracks your nitrogen loading across multiple days of multi-dive profiles. This is essential on a liveaboard where you are doing 3 to 4 dives daily. Make sure the battery is fresh or fully charged before you leave.
SMB and reel. A surface marker buoy is mandatory on Red Sea liveaboards. Currents at offshore sites like Brothers and Daedalus can be unpredictable, and deploying an SMB is your primary way to signal the boat on ascent. Practice deploying it before the trip if you are not confident.
Torch. Even if you are not planning night dives, a small torch is useful for peering into crevices and wrecks during the day. Bring a backup if you have one.
Personal Items and Clothing
Life on a liveaboard is informal. You will spend most of your time in swimwear, a rashguard, or light clothing.
Sun protection. The Egyptian sun is intense, especially on the open water with no shade. Bring reef-safe sunscreen (SPF 50+), a wide-brimmed hat, and UV-protective sunglasses. A long-sleeve rashguard doubles as sun protection on the dive deck and during surface intervals.
Layers for evenings. After sunset, it can get cool on the upper deck, especially in winter months. A lightweight fleece or hoodie is enough. You will not need anything heavy.
Footwear. Flip-flops or reef shoes for the boat. The deck can get hot in direct sun, and you will want something easy to slip on and off. Leave your dress shoes at home — nobody wears them.
Quick-dry towel. Most boats provide towels, but a compact microfibre towel is useful for the dive deck and dries much faster between dives.
Health and Comfort
Seasickness medication. Even experienced sailors can feel queasy on open-water crossings. If you are prone to motion sickness, start taking medication the evening before departure. The crossing to Brothers or Daedalus takes 6 to 12 hours, and conditions can be rough.
Rehydration. You lose more fluid than you realise when diving in warm water. Bring electrolyte tablets or sachets to supplement your water intake. Dehydration increases decompression risk.
Ear care. Multiple dives per day in salt water can irritate your ears. A small bottle of ear-drying drops (alcohol-based) after each dive helps prevent swimmer’s ear.
Basic first aid. Plasters, ibuprofen, any personal medication. The boat carries a full first aid kit and emergency oxygen, but your own basics are handy for minor issues.
Camera Gear
If you are bringing an underwater camera, think about the full setup.
Housing and ports. Double-check all o-rings before the trip. Bring spare o-rings and silicone grease. A single grain of sand can flood a housing.
Batteries and charging. Bring at least two batteries per camera and check that you have the right charging cables. Multi-day liveaboard trips mean you will be shooting hundreds of images — running out of battery on the best dive of the trip is painful.
Memory cards. More than you think you need. Format them before the trip. A backup hard drive or laptop for daily offloading is also worth the luggage space.
Lens cloths and cleaning supplies. Salt spray is constant on a liveaboard. Keep a microfibre cloth accessible for your lens ports between dives.
Documents and Logistics
Dive certification card. Physical or digital — bring both if you can. Some operators require the physical card.
Logbook. Digital or physical. Many dive centres and liveaboard crews will ask to see recent entries to assess your experience level.
Dive insurance documents. Print a copy and save a digital version on your phone. Dive insurance is mandatory on Celesta — DAN or equivalent covering hyperbaric treatment and evacuation.
Passport and travel insurance. Keep copies separate from originals.
What to Leave Behind
You do not need formal clothing, heavy books (use an e-reader), or bulky toiletries — the boat has shampoo and soap. You do not need a full set of weights — they are provided on board. And you do not need to pack for every scenario. A liveaboard is a simple environment. Pack light, pack practical, and leave room in your bag for the memories.
The best liveaboard trips happen when you are comfortable, prepared, and not worrying about what you forgot. Get the essentials right and the Red Sea takes care of the rest.
