10 Essential Dry Bag Packing Items for Boating With Kids

The sun is high, the wake is perfect, and suddenly a wet kid needs a dry change of clothes or a quick snack, only to find everything in the boat’s storage locker is damp. Keeping essential gear dry and accessible is the difference between an unforgettable family day on the water and a shivering, sunburned cruise back to the marina. Packing a dedicated marine dry bag with kids’ essentials ensures that when someone gets cold, hungry, or scraped up, the solution is ready and bone-dry.

How to Pack a Marine Dry Bag for Family Boat Outings

A marine dry bag is only as effective as the logic behind how it is packed. On a 20-foot bowrider or a center console, space is tight, and rummaging through a deep bag during a sudden squall or a temper tantrum is a recipe for chaos. Start by laying out all gear and organizing it by frequency of use and vulnerability to water.

Place heavy, low-priority items like spare dry clothes and extra towels at the bottom of the bag to create a stable base. Middle layers should contain lunchboxes and water bottles, while emergency gear, sunscreen, and first aid kits must sit right at the top for immediate access.

To achieve a true watertight seal, compress the bag to force out excess air before rolling the top collar down at least three to four times. Skipping this step or leaving too much air inside results in a bulky bag that resists tight stowing and might leak if submerged in the bilge.

Packable Towel – PackTowl Personal Microfiber Towel

Standard cotton beach towels are the enemy of a well-packed boat bag. They are bulky, slow to dry, and act like sponges for bilge water. A high-performance microfiber towel solves this problem by offering maximum absorbency in a package that rolls down to the size of a water bottle.

The PackTowl Personal Microfiber Towel is the gold standard for marine use because it absorbs four times its weight in water and dries up to 70% faster than cotton. It also features a Polygiene odor control treatment, preventing that sour, damp-dog smell from taking over the boat storage locker after a long afternoon of tubing. This odor prevention is crucial when towels are stored wet during the trip home.

• Material: 85% Polyester, 15% Nylon microfiber
• Sizes: Face, Hand, Body, and Family sizes
• Maintenance: Machine washable and includes a zippered mesh storage pouch

For boating with kids, opt for the Body or Family size to ensure full wrap-around warmth when the wind picks up. Avoid using fabric softeners when washing this towel, as softeners coat the fibers and drastically reduce its water-wicking ability over time.

This towel is ideal for families operating out of small boats or kayaks where storage space is at an absolute premium. It is not the right choice for boaters who prioritize plush, heavy, traditional cotton luxury over packability and rapid drying times.

Kids Sunscreen – Thinkbaby Safe Sunscreen SPF 50+

Sunlight reflects off the water’s surface, doubling the UV exposure kids receive during a boat day. Sun protection is non-negotiable on open water. Keeping a reliable, non-leaking tube of high-SPF sunscreen in the dry bag prevents painful burns and ruined weekends.

Thinkbaby Safe Sunscreen SPF 50+ is a mineral-based formula utilizing 20% non-nano Zinc Oxide to provide broad-spectrum UVA and UVB protection. It is highly water-resistant for up to 80 minutes and contains no biologically harmful chemicals, making it safe for both sensitive young skin and delicate marine ecosystems.

• Active Ingredient: 20% Zinc Oxide (non-nano)
• Water Resistance: Rated for 80 minutes
• Eco-Safety: Reef-friendly formulation free of oxybenzone and octinoxate

Because mineral sunscreens sit on top of the skin rather than absorbing into it, application requires a bit of effort to rub in thoroughly. Always apply this sunscreen before leaving the dock to allow it to bond with the skin without the interference of salt spray or sweat.

This sunscreen is perfect for parents seeking maximum skin safety and compliance with reef-safe regulations in national parks and marine sanctuaries. It is not ideal for those who prefer clear chemical sprays, though sprays often blow away in the sea breeze anyway.

Youth Rash Guard – O’Neill Youth Basic Skins UPF 50+

Wet skin rubbing against a bulky personal flotation device (PFD) causes painful chafing within minutes of leaving the wake. A high-quality rash guard acts as a physical barrier against life jacket straps, salt spray, and relentless overhead sun. It keeps kids comfortable so they can stay in the water longer.

The O’Neill Youth Basic Skins UPF 50+ features premium four-way stretch fabric that moves with the child while blocking 99% of harmful UV rays. Its flatlock stitched seams are strategically placed to prevent underarm and chest irritation during heavy paddling or boarding sessions.

• UV Protection: UPF 50+ U.V. protection factor
• Material: 6-ounce Polyester/Spandex blend
• Fit: Slim, ergonomic fit to prevent bunching

Note that O’Neill rash guards are designed to fit snugly to prevent the fabric from riding up in the water. If the child dislikes tight clothing or is in between sizes, purchasing one size up provides a more comfortable, relaxed fit without sacrificing protection.

This garment is a must-have for active youth who spend hours swimming, tubing, or wakeboarding behind the boat. It is less suited for kids who will only remain under the boat’s bimini top and prefer loose-fitting cotton clothing.

Marine First Aid Kit – Adventure Medical Kits Marine

From stray fishhooks and sharp barnacles to sudden motion sickness, minor medical emergencies are a reality of family boating. A standard household first aid kit will quickly disintegrate in a marine environment. This makes a specialized, waterproof marine kit an absolute necessity for your dry bag.

The Adventure Medical Kits Marine series features a durable, water-resistant outer case containing organized, waterproof inner pockets to keep supplies bone-dry. It includes specialized marine treatments like motion sickness medication, eye wash, and heavy-duty wound care supplies tailored for saltwater environments.

• Packaging: Water-resistant outer case with clear, organized inner compartments
• Medications: Includes remedies for motion sickness, pain, and allergies
• Supplies: Tailored for wound care, burns, and splinter removal

This kit should always be packed at the very top of the dry bag for instant access when an injury occurs. Check the kit annually before the boating season begins to replace expired medications and replenish used bandages or antiseptic wipes.

This kit is indispensable for families exploring coastal waterways, larger lakes, or areas far from immediate medical assistance. It may be more comprehensive than necessary for short pontoon rides on small municipal reservoirs, though safety always favors preparedness.

Leak-Proof Lunch Box – Bentgo Kids Brights Bento Box

Sandwiches crushed by shifting anchors and soggy crackers soaked by sea spray will quickly end a boat day in tears. Keeping kids’ snacks secure requires a rigid, sealed container that can handle the motion of a boat crossing a choppy bay. Standard plastic bags simply will not cut it in a moving vessel.

The Bentgo Kids Brights Bento Box features a drop-proof design with rubber-coated edges that prevent sliding on slippery fiberglass decks. Its five practical compartments are sealed individually by a molded rubber lid, ensuring that applesauce, berries, and sandwiches never mix or leak into the rest of the dry bag.

• Compartments: 5 portioned sections
• Durability: Drop-proof, rubber-molded bumpers
• Safety: BPA-free, food-safe materials

To maintain the integrity of the leak-proof silicone seal, always hand-wash the outer shell, even though the inner tray is dishwasher-safe. While it handles thick liquids like Greek yogurt or hummus perfectly, avoid packing thin liquids like juice or soup, which can compromise the internal seals under heavy vibration.

This bento box is ideal for toddlers and young children who prefer variety and need their snacks kept pristine in rough water. It is not designed for teenagers or adults with larger appetites, who will require larger container options.

Kids Water Bottle – YETI Rambler Jr. 12 oz Kids Bottle

Dehydration happens quickly on the water, accelerated by wind, sun, and physical activity. Cheap plastic bottles sweat condensation inside the dry bag and allow drinking water to turn lukewarm and unappealing within an hour of departure. Keeping beverages ice-cold is essential to keep kids drinking.

The YETI Rambler Jr. 12 oz Kids Bottle utilizes double-wall vacuum insulation to keep water icy cold even when sitting on a sun-baked fiberglass console. Constructed from kitchen-grade 18/8 stainless steel, this bottle will not dent, puncture, or crack when dropped onto a hard deck or tossed into the bilge.

• Material: 18/8 Stainless steel with DuraCoat finish
• Cap Type: Leak-resistant straw cap
• Cleanability: Dishwasher safe for easy maintenance

The straw cap is highly leak-resistant when folded down, but it must be closed completely before placing the bottle back into the dry bag. In high-humidity marine environments, disassemble the cap and run it through the dishwasher regularly to prevent mold from forming in the silicone seals.

This bottle is perfect for parents who want an indestructible, cold-retaining bottle that survives years of rough boat use. It is less suitable for paddleboarding or kayaking families looking for ultra-lightweight, collapsible squeeze bottles.

Youth Rain Jacket – Columbia Youth Glennaker Jacket

A sudden afternoon squall or a high-speed cruise back to the marina at sunset can quickly drop the temperature on the water. Having a lightweight, windproof, and waterproof layer stowed in the dry bag keeps shivering at bay and prevents hypothermia. This is the ultimate backup plan for changing marine weather.

The Columbia Youth Glennaker Jacket is made from lightweight Hydroplus waterproof nylon that packs down tightly without taking up valuable dry bag volume. It features a fitted hood, elastic cuffs, and reflective safety detailing, which is highly useful for visibility in low-light marina environments.

• Fabric: 100% Hydroplus nylon shell
• Pockets: Dual zippered hand pockets
• Safety: Reflective detailing for visibility

When selecting a size, choose one that leaves enough room to layer over a thick fleece or a low-profile life jacket. After exposure to saltwater spray, always rinse the jacket with fresh water and allow it to dry completely before packing it away to protect the waterproof coating.

This jacket is an excellent option for recreational day boating where quick, reliable weather protection is needed. It is not designed to serve as heavy-duty, commercial-grade foul weather gear for extended offshore storms.

Portable Power Bank – Anker PowerCore 10000 Charger

Marine navigation apps, emergency weather updates, and taking photos of the day’s catch will drain a smartphone battery rapidly. Out on the water, cellular devices also use more power as they constantly search for distant shore-based towers. This makes a backup power source a critical safety essential.

The Anker PowerCore 10000 Charger is one of the smallest and lightest external batteries on the market, delivering over three full charges to most smartphones. It features PowerIQ high-speed charging technology and a robust outer shell designed to withstand the vibration and minor impacts of a bumpy boat ride.

• Capacity: 10,000 mAh
• Output: 12W high-speed charging
• Size: Compact, card-like footprint

While the dry bag provides primary water protection, always store the power bank in an additional ziplock bag inside to shield it from wet hands. Never attempt to plug a charging cable into the power bank or your phone if either port has been exposed to salt spray, as this causes instant electrical corrosion.

This charger is an essential piece of safety gear for captains relying on mobile phones for backup GPS navigation and weather tracking. It is less critical for vessels equipped with built-in, hardwired USB charging ports, though it still serves as an excellent emergency backup.

Kids Sunglasses – Tifosi Optics Swank Kids Sunglasses

Water reflects up to 80% of sunlight, exposing young eyes to intense glare that causes rapid fatigue and headaches. Protecting a child’s eyes on the water requires specialized sunglasses that block harmful rays and stay securely on active faces. Standard fashion glasses do not offer the optical clarity needed for marine safety.

The Tifosi Optics Swank Kids Sunglasses are constructed with Grilamid TR-90 frames, a lightweight nylon material famous for its extreme durability and resistance to UV bending. The scratch-resistant, shatterproof polycarbonate lenses offer 100% UVA/UVB protection, ensuring safe vision during high-speed runs across the water.

• Frame Material: Grilamid TR-90 homopolymer nylon
• Lenses: Shatterproof, scratch-resistant polycarbonate
• Fit: Tailored for small youth faces

Note that these sunglasses do not float on their own if dropped overboard. To prevent losing them in the lake, always pair them with a floating neoprene eyewear retainer strap and rinse them with fresh water to clear salt crust before wiping.

These glasses are perfect for parents who want durable, high-performance eye protection that mimics adult sports optics. They are not the best choice for infants or toddlers who require soft, strap-only baby sunglasses.

Biodegradable Wipes – WaterWipes Plastic-Free Wipes

Sticky hands from melted snacks, slimy fingers from holding bait, and dried sunscreen eyes are inevitable when boating with kids. When fresh running water is unavailable onboard, a pack of wet wipes is the most valuable tool in the dry bag. They provide a quick cleanup before handling gear or steering.

WaterWipes Plastic-Free Wipes contain 99.9% purified water and a drop of fruit extract, making them safe for sensitive skin, eyes, and mouths. Because they are made from 100% biodegradable viscose, they are a more environmentally conscious choice for marine use than standard synthetic plastic wipes.

• Ingredients: 99.9% water, trace fruit extract
• Material: 100% plastic-free, biodegradable viscose
• Safety: Hypoallergenic and fragrance-free

Always ensure the adhesive seal on the package is completely closed after each use, as dry wind and hot sun will quickly sap the moisture from the wipes. Remember that “biodegradable” does not mean “throw overboard”; all used wipes must be bagged and disposed of in proper trash receptacles back at the marina.

These wipes are a must-have for families with infants, toddlers, or kids prone to sticky messes and sunscreen irritation. They are not meant to replace heavy-duty marine hand cleaners designed to strip away engine grease or heavy boat grime.

Organizing and Waterproofing Your Family Boating Gear

Success on the water is all about organization and preventing the “black hole” effect inside a large 30-liter dry bag. Use smaller, color-coded mesh pouches or lightweight dry sacks inside the main bag to separate electronics, first aid, and spare dry clothes. This ensures you can grab what you need without dumping the entire contents on a wet deck.

Marine environments are harsh on gear, especially when saltwater is involved. After every boating trip, empty the dry bag completely and inspect the seams. Rinse both the interior and exterior with fresh water, then hang it upside down to dry in a shaded area.

Pay close attention to the buckles, d-rings, and roll-top seams during cleaning. Salt residue left on plastic buckles can make them brittle over time, leading to sudden failure. Furthermore, trapped moisture in a closed bag will quickly grow black mold that ruins fabrics and smells terrible.

Conclusion

A well-stocked dry bag is the ultimate insurance policy for a fun, stress-free family boat day. By investing in durable, marine-grade gear and packing it methodically, parents can handle wind, waves, and wet kids with confidence. Get the dry bag packed, double-check the safety gear, and enjoy your time on the water.
