9 Essential Catamaran Day Trip Packing List Items for Families

Stepping onto a spacious catamaran for a family day trip promises wind-in-your-hair excitement, but the open water can quickly turn challenging without the right preparation. Unlike standard monohull boats, catamarans offer unique netting and deck spaces that demand specialized gear to keep everyone safe, dry, and comfortable. Packing the wrong equipment can lead to soaked electronics, sunburned kids, or worse, so having a targeted gear checklist is essential for a seamless day on the water.

Preparing Your Family for a Day on a Catamaran

A catamaran day trip offers incredible stability, but the combination of reflective water, constant sea breezes, and open trampoline netting requires deliberate preparation. Children often do not realize how quickly the sun and wind can drain their energy until they are already exhausted or sunburned. Laying out clear expectations before boarding—such as where they can safely walk and when life jackets must be worn—ensures a fun, stress-free outing for everyone.

Unlike deep-cockpit keelboats, catamarans have wide, flat decks where wind can easily snatch away loose gear or hats. Saltwater spray is a constant companion, meaning everything brought on board must either handle a drenching or be sealed away in watertight storage. Preparing your family means packing light, packing smart, and focusing on high-performance gear that handles both the motion of the vessel and the harsh marine elements.

Dry Bag – Sea to Summit Big River Dry Bag

A high-quality dry bag is your first line of defense against the relentless saltwater spray and sudden downpours common on open catamaran decks. Standard backpacks will quickly soak through, ruining dry clothing, lunches, and sensitive electronics. This bag keeps your essential gear bone-dry and organized in a single, easily transportable package.

The Sea to Summit Big River Dry Bag is built from heavy-duty 420D nylon, making it incredibly abrasion-resistant when dragged across non-skid catamaran decks. The roll-top closure secured with a durable buckle creates a watertight seal that easily withstands heavy spray and temporary submersion. With multiple lash points, it secures effortlessly to the boat’s rigging or stanchions so it won’t slide overboard in rougher seas.

• Material: 420D TPU-laminated nylon
• Closure: Waterproof roll-top with field-replaceable buckles
• Best For: Storing dry clothing, towels, and mid-sized electronics

This rugged bag is perfect for families who need uncompromising water protection for gear that cannot get wet under any circumstances. However, because it lacks backpack-style shoulder straps in its standard configuration, it is less suited for long shore excursions where hands-free hiking is required.

Kids Life Jacket – Stearns Infant Classic Series

Safety is the absolute priority on any boating excursion, especially for non-swimmers or toddlers who can slip through catamaran lifelines. A properly fitted personal flotation device (PFD) keeps young children safe in the water and provides parents with invaluable peace of mind. On a catamaran, a bright, highly visible life jacket is essential whenever kids are on deck.

The Stearns Infant Classic Series life jacket is US Coast Guard-approved and designed specifically for youngsters under 30 pounds. It features a crucial oversized head-support pillow that forces an infant to float face-up in the water, providing vital seconds in an emergency. The durable nylon shell and webbed straps, including a secure crotch strap, ensure the jacket stays firmly attached without riding up over the child’s chin.

• Weight Rating: Under 30 lbs
• Approval: USCG Type II
• Key Feature: Grab handle on the collar for quick retrieval

This is an absolute necessity for families with infants or toddlers boarding any recreational vessel. It is not suitable for older, larger kids who require Type III vest-style jackets that allow for more active swimming and paddleboarding.

Reef Safe Sunscreen – Thinksport SPF 50+ Sunscreen

Sun protection is critical when spending hours on a catamaran, where the sun reflects off both the white fiberglass decks and the surrounding water. Traditional sunscreens contain chemicals that wash off into the water and damage fragile marine ecosystems, particularly coral reefs. Using a mineral-based, reef-safe sunscreen protects your family while preserving the underwater sights you came to see.

The Thinksport SPF 50+ Sunscreen relies on a zinc oxide formula that provides broad-spectrum UVA and UVB protection without using harmful chemicals like oxybenzone or octinoxate. It boasts the highest level of water resistance allowed by the FDA (80 minutes), meaning it won’t immediately wash off when the kids jump off the catamaran bow. The mineral-based cream applies smoothly without leaving an excessively greasy residue, which is vital for maintaining a solid grip on boat railings.

• Active Ingredient: 20% Zinc Oxide (Non-nano)
• Water Resistance: 80 minutes
• Safety Rating: EWG Verified

This sunscreen is ideal for families swimming near coral reefs or marine sanctuaries where eco-friendly formulas are legally mandated. It may not appeal to those who prefer instant-drying aerosol sprays, as mineral formulas require thorough rubbing to eliminate the white protective layer.

Kids Water Shoes – Keen Kids Newport H2 Water Sandal

Catamaran decks can get scorching hot under the midday sun, and fiberglass gelcoat can become incredibly slick when wet. Furthermore, family day trips often include beach landings or wading through shallow, rocky waters. A dedicated pair of water shoes protects small feet from cuts, burns, and slips without needing to constantly change footwear.

The Keen Kids Newport H2 Water Sandal combines the breathability of a sandal with the robust toe protection of a trail shoe. The non-marking rubber outsole provides exceptional grip on wet fiberglass, preventing slips when children move around the trampoline area. Its washable polyester webbing dries quickly and stands up to the harsh effects of salt and sand without stiffening or chafing delicate skin.

• Upper: Washable polyester webbing
• Outsole: Non-marking rubber with multi-directional lugs
• Closure: Secure-fit lace capture system with hook-and-loop strap

These sandals are perfect for active kids who transition constantly from the catamaran deck to wet sand and rocky shorelines. They are not designed for deep-water swimming, as the sturdy protective design can feel somewhat heavy and drag-heavy once fully submerged.

Packable Towel – Rainleaf Microfiber Travel Towel

Traditional cotton beach towels are bulky, take hours to dry, and quickly become heavy and musty when exposed to salt air. On a catamaran, space is at a premium, and damp towels left lying around create slipping hazards on deck. A lightweight, packable travel towel resolves these issues by drying rapidly and packing down incredibly small.

The Rainleaf Microfiber Travel Towel absorbs up to three times its weight in water while drying exceptionally fast in the sea breeze. It features a built-in hang loop with a snap, allowing you to secure it safely to the catamaran’s lifelines or rigging to dry without fear of it blowing away. This lightweight towel folds down to the size of a small book, freeing up crucial storage space in your dry bag for other essentials.

• Material: 85% Polyester, 15% Polyamide microfiber
• Sizes: Small to XX-Large (X-Large is ideal for body drying)
• Features: Snap-loop hanging strap and breathable mesh carry bag

This is a must-have for families looking to cut down on bulk and avoid the musty smell of soggy cotton towels on a boat. It is not the right choice for those who prefer the plush, heavy feel of traditional terrycloth, as microfiber has a distinct “suede” texture that grabs the skin differently.

Floating Sunglasses – Rheos Gear Eddies Sunglasses

Staring at the water for hours can cause severe eye strain due to the intense glare reflected off the sea. Polarized sunglasses are essential for cutting this glare, allowing you to see underwater obstacles, reefs, and marine life clearly. However, standard sunglasses sink like stones the moment they slip off your face into the deep ocean.

Rheos Gear Eddies Sunglasses are constructed from a specialized ultralight TPX material that allows them to float horizontally on the water’s surface for easy retrieval. The polarized lenses feature a premium anti-fog, anti-scratch, and hydrophobic coating that sheds saltwater droplets instantly for clear vision. They offer 100% UV protection, which is essential when navigating open water for hours at a time.

• Frame Material: Floating TPX polymer
• Lens Type: Polarized nylon with hydrophobic coating
• Fit: Medium to large wrap-around style

These glasses are perfect for anyone helming the catamaran, spotting marine life, or riding in the bow net where splashes are guaranteed. They may not fit exceptionally small faces or toddlers, who will require dedicated children’s floating sunglasses with strap retainers.

Waterproof Phone Case – JOTO Waterproof Pouch

A day on a catamaran offers endless photo opportunities, but salt water and sensitive electronics are a disastrous combination. Dropping your phone onto a wet deck or into the sea can instantly ruin your device and destroy your vacation memories. A reliable waterproof pouch allows you to take photos safely, navigate, and keep your phone accessible without risking water damage.

The JOTO Waterproof Pouch features an IPX8 waterproof rating, keeping your device safe in depths up to 100 feet while allowing full touch-screen functionality. The clear window on both sides ensures you can snap vibrant photos of sailing maneuvers or marine wildlife without exposing your phone to salty air. A secure snap-and-lock seal at the top prevents even a single drop of water from entering, while the included neck lanyard keeps the phone securely attached to you.

• Waterproof Rating: IPX8 certified
• Compatibility: Fits smartphones up to 7.0 inches diagonally
• Material: Durable PVC/TPU with a secure dual-swivel lock

This pouch is perfect for boaters who want to take photos near the water’s edge or keep their phone close at hand on a wet deck. It is not ideal for high-definition underwater videography, as the plastic barrier can slightly distort focus or muffle audio underwater.

Marine Cooler – RTIC Everyday Cooler Bag 15 Can

Staying hydrated is critical during a day under the sun, as the ocean breeze can mask how much you are sweating. While many catamarans have onboard refrigeration, a dedicated family cooler ensures quick access to cold drinks and snacks without tracking sand into the cabin. A soft-sided marine cooler is easier to store and much gentler on the boat’s fiberglass than a heavy, rigid plastic box.

The RTIC Everyday Cooler Bag 15 Can utilizes closed-cell foam insulation to keep ice frozen for up to 24 hours, ensuring cold hydration throughout your entire trip. The durable exterior fabric is water-resistant and easy to wipe down, preventing saltwater stains and mold growth. Unlike rigid hard coolers that can slide around and damage gelcoat, this soft-sided bag features a non-slip bottom that stays put on moving catamaran decks.

• Capacity: 15 cans plus ice
• Insulation: High-density closed-cell foam
• Portability: Adjustable padded shoulder strap and side handles

This is the ultimate mid-sized cooler for a family day trip, fitting easily into tight companionways or under deck seating. It is not designed for multi-day voyages where massive dry-ice capacity or heavy-duty, bear-proof latching is required.

Motion Sickness Relief – Dramamine Less Drowsy

Even the most stable catamaran can experience a rhythmic, rolling motion when crossing deep ocean swells or navigating choppy channels. Seasickness can quickly turn a highly anticipated family adventure into a miserable experience for children and adults alike. Having a proven motion sickness preventative on hand ensures the trip isn’t cut short by sudden nausea.

Dramamine Less Drowsy contains meclizine hydrochloride, which target-treats motion sickness symptoms for up to 24 hours with significantly less fatigue than original formulas. While catamarans are highly stable, the subtle swaying motion over deep ocean swells can still trigger the inner ear of sensitive passengers. Taking this formula before boarding helps prevent nausea, dizziness, and vomiting, allowing everyone to enjoy the scenery and the ride.

• Active Ingredient: Meclizine HCl (25 mg per tablet)
• Duration: 24-hour relief
• Age Range: Safe for adults and children 12 years and older (consult a pediatrician for younger children)

This is highly recommended for any passenger who is unsure of their “sea legs” or prone to car sickness. It is not suitable for children under the age of 12 unless explicitly approved by a doctor, meaning families with toddlers should opt for pediatric-specific formulations or acupressure bands instead.

Crucial Catamaran Safety Tips for Younger Children

Catamarans are incredibly inviting to children because of their wide-open trampoline nets suspended between the two hulls. However, this netting can bounce like a trampoline when hitting waves, making it easy for a small child to lose their balance or slip. Establish a strict rule that children must remain seated or hold an adult’s hand whenever the catamaran is moving at cruising speeds or navigating choppy channels.

The transition areas between the indoor salon and the outdoor cockpit are often flush on catamarans, but they still present trip hazards like sliding door tracks and low-profile cleats. Ensure children wear their water shoes at all times on deck to maintain traction on wet fiberglass surfaces and prevent stubbed toes. Before setting sail, point out the “danger zones” like the windlass winch, the mainsheet traveler, and the areas near the hot engine hatches.

How to Pack Smart for Limited Trampoline and Deck Space

While catamarans offer more deck space than monohulls of a similar length, clutter can quickly become a serious safety hazard during sailing maneuvers. A stray bag left on the trampoline can easily catch the wind, slide overboard, or obstruct the path of a crew member adjusting a sail. Instruct each family member to bring only one soft-sided bag that can squash down flat when empty, rather than rigid, structured backpacks.

Utilize the vessel’s built-in storage lockers or cabin spaces for gear that isn’t immediately needed, keeping the cockpit clear of obstacles. Hang wet towels from designated lifelines using spring clips or snap loops immediately rather than piling them on the deck where they create slipping hazards. By keeping a clean deck, you ensure that the captain has unobstructed sightlines and the crew has clear paths to manage lines safely.

With the right selection of safety gear, weather protection, and marine-grade storage, your catamaran excursion will be a highlight of your family’s vacation. Investing in high-quality, boat-friendly equipment ensures you spend your time soaking in the ocean views rather than dealing with soggy gear or preventable mishaps. Pack smart, brief the kids on safety, and enjoy the unparalleled freedom of sailing on two hulls.
