10 Essential Boating Accessories for Active Lake House Guests

Welcoming friends to a lake house for a weekend of boating is one of the greatest pleasures of owning a waterfront property. However, unprepared guests can quickly turn a relaxing day on the water into a logistical headache of soggy towels, lost phones, and safety concerns. Equipping your visitors with the right gear ensures everyone stays safe, comfortable, and ready for whatever the lake throws their way.

How to Prepare Your Lake House Guests for the Water

Hosting on the water requires proactive planning before anyone steps onto the dock. Guests who visit from landlocked areas often underestimate the power of wind, sun, and sudden temperature shifts on a 20-foot bowrider. Sending a quick checklist of what to bring—and prepping your boat with guest-friendly gear—prevents minor emergencies before they start.

Safety is the absolute priority, but comfort is what keeps people smiling during a long afternoon of tubing or cruising. A solid preparation strategy involves establishing clear zones on the boat for dry storage, wet gear, and hydration. Having designated, user-friendly gear ready for your guests ensures they feel secure without needing constant supervision.

Waterproof Dry Bag – Sea to Summit Big River Dry Bag

A day on the lake involves a constant battle between wet and dry items. Traditional backpacks quickly soak through on a boat deck, ruining dry clothes, fleece layers, and physical wallets. A dedicated dry bag keeps guest essentials dry, organized, and shielded from heavy lake spray or unexpected rain showers.

The Sea to Summit Big River Dry Bag is a rugged, mid-weight dry bag constructed from TPU-laminated 420D nylon. This heavy-duty fabric resists punctures and abrasions from rough boat decks, aluminum pontoon railings, and gravel shorelines. The white interior laminate increases visibility, making it easy for guests to find their gear at the bottom of the bag.

• Capacity options: 5L, 8L, 13L, 20L, 35L, and 65L
• Best use: Stashing extra dry layers, towels, and valuable electronics
• Key feature: Low-profile lash loops for securing to boat rails or kayak decks

Before tossing this bag into the water, ensure the roll-top closure is folded at least three times before clicking the buckle. While the waterproof fabric and taped seams are incredibly reliable, this bag is designed for surface use and should not be fully submerged for extended periods. It is the perfect choice for active boat riders, kayakers, and paddleboarders who need reliable splash protection.

Floating Sunglasses – Rheos Gear Eddies Polarized

Standard sunglasses sink like stones the moment a guest wipes out on a wakeboard or leans too far over the gunwale to grab a dock line. Losing an expensive pair of designer sunglasses can instantly sour a guest’s mood. Floating sunglasses solve this common lake-day headache without requiring dorky neoprene retaining straps.

The Rheos Gear Eddies Polarized sunglasses feature an ultra-lightweight frame material designed to float naturally on the water’s surface. The polarized lenses offer complete UV protection and feature dual-sided anti-scratch and hydrophobic coatings that shed lake water instantly for clear vision. The frames are styled like classic activewear, so guests look great both on the boat and at the lakeside restaurant.

• Frame style: Classic sport-casual wrap
• Lens technology: Polarized NYPO tech with anti-fog properties
• Floating capability: High-buoyancy geometry floats frame-up

Because these sunglasses are designed to float, they are incredibly lightweight, which some guests may mistake for a cheap build. However, the impact-resistant construction is highly durable and designed to take a beating. These are ideal for anyone active on jet skis, tubes, or paddleboards, though they may not fit guests with exceptionally narrow face shapes.

Marine Cooler – RTIC 20 Quart Ultra-Light Cooler

A hot day on the water demands constant hydration, and nobody wants to walk back to the house every time they need a cold drink. A compact, portable marine cooler keeps beverages icy and lunch meat fresh without monopolizing valuable deck space on a day boat.

The RTIC 20 Quart Ultra-Light Cooler is engineered to be 30% lighter than standard rotomolded coolers of the same capacity. This weight reduction is a game-changer when carrying a fully loaded cooler down a long dock or steep lake stairs. It features heavy-duty T-latches, a freezer-grade gasket, and injection-molded insulation that keeps ice frozen for days, not hours.

• Capacity: Up to 24 cans with a 2:1 ice-to-can ratio
• Empty weight: 13 pounds
• Features: Built-in heavy-duty carrying handle and integrated drain plug

To get the best performance out of this cooler, pre-chill it with a sacrificial bag of ice the night before your trip. This cools the insulation down so your actual trip ice does not immediately melt trying to cool the cooler walls. This size is perfect for a small group of day boaters, but larger parties staying out past dusk may require a secondary, larger chest.

Inflatable PFD – Onyx M-24 Manual Inflatable Belt Pack

Traditional Type III life jackets are bulky, hot, and restrict movement, which tempts many active guests to leave them off entirely. An inflatable belt pack PFD provides the legal safety requirement and peace of mind without the physical bulk of a traditional vest.

The Onyx M-24 Manual Inflatable Belt Pack sits comfortably around the waist like a small fanny pack. If a guest finds themselves in trouble in deep water, a quick pull on the manual T-cord inflates the internal bladder using a CO2 cylinder, providing immediate buoyancy. The low-profile design allows for unrestricted movement while paddling, fishing, or lounging on the boat.

• USCG rating: Type V with Type III performance
• Inflation style: Manual pull-cord (CO2 cylinder included)
• Sizing: Universal fit for adults over 80 pounds

This PFD is manually operated, meaning it will not inflate automatically when it hits the water. This is an intentional design choice to prevent accidental inflation during active swimming or wakeboarding, but it requires the wearer to be conscious to pull the cord. It is highly recommended for strong, adult swimmers, but is absolutely not suitable for children or non-swimmers.

Waterproof Phone Case – JOTO Universal Waterproof Pouch

Guests love capturing photos and videos of their lake weekend, but smartphones and open water do not mix. A dropped phone can quickly slip into the dark depths of the lake, resulting in lost memories and a costly replacement. A simple, floating waterproof pouch keeps the phone secure, dry, and fully functional.

The JOTO Universal Waterproof Pouch features an easy-to-use snap-and-lock seal that provides IPX8 certified waterproof protection. The clear window material allows guests to use their phone’s touchscreen to text, call, and take photos without removing the device from the pouch. It also comes with a durable neck lanyard to prevent the phone from slipping out of wet hands.

• Compatibility: Fits virtually all smartphones up to 7.0 inches
• Waterproof depth: IPX8 certified up to 100 feet
• Design: Clear front and back windows for photo-taking

While touchscreens work perfectly through the plastic on dry land, water pressure can make touch inputs unresponsive underwater. To take photos while floating in the lake, guests should set up their camera app beforehand and use the phone’s physical volume buttons to snap the picture. This pouch is cheap insurance for any guest boarding a boat, kayak, or paddleboard.

Waterproof Speaker – JBL Clip 4 Portable Bluetooth Speaker

A lake day is not complete without a proper soundtrack, but delicate home speakers cannot survive the splashing, dust, and damp environments of a boat. A rugged, waterproof speaker lets you bring the music directly to the swim platform or sandbar without worry.

The JBL Clip 4 Portable Bluetooth Speaker features an IP67 waterproof and dustproof rating, meaning it can survive a drop into shallow water or a sudden downpour. It is designed with an integrated carabiner clip that easily attaches to boat bimini frames, backpack straps, or kayak rigging. Despite its compact, pocket-sized design, it delivers rich, punchy audio that easily cuts through the sound of wind and water.

• Battery life: Up to 10 hours of playtime
• Charging port: USB-C (cable included)
• Durability: IP67 waterproof and dustproof

It is important to note that the JBL Clip 4 does not float on its own. Always ensure the carabiner is securely clipped to a secure point on the boat or PFD when traveling over open water. This speaker is perfect for personal use or small boat groups, though it will not provide enough volume to power a large dock party.

Packable Towel – Nomadix Original Quick-Dry Towel

Traditional cotton towels are heavy, slow to dry, and take up massive amounts of storage space in a boat’s under-seat compartments. After one swim, a cotton towel becomes a soggy, heavy mass that gathers sand, dirt, and mildew odors. A modern packable towel solves these space and drying issues instantly.

The Nomadix Original Quick-Dry Towel is crafted from post-consumer recycled plastic bottles but feels remarkably soft to the touch. This high-performance towel absorbs four times its weight in water and dries four times faster than standard cotton. It packs down to the size of a water bottle, allowing you to easily store half a dozen towels in a single boat locker.

• Dimensions: 30″ x 72″ (full body size)
• Material: 80% Recycled Polyester, 20% Nylon
• Key benefit: Sand-resistant fabric sheds debris with a quick shake

Microfiber towels have a different, more slip-resistant feel against the skin compared to plush cotton towels, which can take some getting used to. However, their superior packability and quick-drying nature make them vastly superior for boat use. They are the ideal choice for guests who plan on hopping in and out of the water all afternoon.

Marine Multi-Tool – Gerber MP600 Multi-Plier

Minor mechanical issues can quickly stall a lake day, whether it is a stuck battery terminal, a tangled fishing line, or a loose bimini screw. Having a high-quality, marine-grade multi-tool on hand allows you or your guests to make quick adjustments without driving all the way back to the dock tool chest.

The Gerber MP600 Multi-Plier features a patented one-handed opening design, which is incredibly useful when your other hand is busy holding a dock line or steering wheel. Built with high-grade stainless steel, this tool houses 14 individual implements, including a serrated blade, rotatable carbide wire cutters, and heavy-duty pliers. The rugged construction resists the harsh, humid environments common to boat storage compartments.

• Closed length: 4.9 inches
• Weight: 9.0 ounces
• Implements: Pliers, wire cutters, knives, screwdrivers, bottle opener, and file

Even though this tool is built from high-grade stainless steel, freshwater minerals can cause corrosion over time if the tool is stored wet. Always rinse the tool with fresh water and dry it completely before storing it back in its sheath. This tool is a must-have for the boat’s glove box, though it is not designed to replace heavy-duty socket sets for major engine repairs.

Changing Robe – Slowtide Quick-Dry Changing Poncho

Changing out of a wet swimsuit on a boat or at a busy public dock can be a logistical and modesty challenge. A changing robe acts as a mobile changing tent, allowing guests to transition from wet swimsuits to dry clothes comfortably and discreetly.

The Slowtide Quick-Dry Changing Poncho is woven from highly absorbent micro-fiber material that dries quickly while keeping the wind off wet skin. It features double-sided side pockets for easy access to your undergarments while changing, and a cozy hood to dry wet hair. The roomy, oversized fit ensures guests of all sizes have plenty of space to maneuver.

• Sizes available: Small/Medium and Large/X-Large
• Material: 100% Recycled post-consumer waste
• Features: Snap-front placket with drawcords

Because these ponchos are designed to be extremely oversized to facilitate changing, they can look quite bulky when worn casually. They are not meant to be a fashion statement, but rather a highly functional utility garment. This is the ultimate accessory for guests who plan to stay on the water past sunset when the air temperature begins to drop.

Handheld VHF Radio – Standard Horizon HX210 Marine Radio

On larger lakes, cell phone service can be notoriously spotty, making it difficult to call for assistance or check changing weather radar. A marine handheld VHF radio provides a direct lifeline to local lake patrols, emergency services, and fellow boaters in your area.

The Standard Horizon HX210 Marine Radio is a compact, floating 6W handheld radio with a high-resolution dot matrix display. If the radio falls overboard, a water-activated strobe light flashes automatically—even if the unit is turned off—to help you locate it in the dark. It covers all US, International, and Canadian marine channels, plus receives NOAA weather alerts to warn you of approaching storms.

• Transmit power: Selectable 6W, 2.5W, or 1W output
• Battery: 1850 mAh Li-Ion with a 3-hour desktop rapid charger
• Waterproof rating: IPX7 (3.3 feet for 30 minutes)

VHF radios operate on a line-of-sight basis, meaning their range can be limited by tall lake bluffs, heavy tree lines, or islands. In open water, expect a reliable range of 3 to 5 miles, which is more than enough for most inland lakes. This is a critical safety item for guests taking out secondary vessels like jet skis or kayaks far from the main house.

How to Store and Maintain Guest Gear After a Lake Day

The end of a successful lake day shouldn’t lead to a pile of damp gear rotting in the back of an SUV or on the deck of the boat. Proper post-ride maintenance preserves the life of your equipment and keeps your lake house smelling fresh. Create a designated outdoor gear station with heavy-duty hangers for life jackets, drying racks for towels, and a hose station to rinse off freshwater lake residue.

Before packing away dry bags, speakers, or multi-tools, ensure they are thoroughly wiped down and dried out of direct sunlight to prevent UV damage. Empty the marine cooler, wash it with mild dish soap, and prop the lid open to prevent mildew from forming in the seal. Taking these quick, systematic steps at dusk ensures that when tomorrow’s sun rises, the entire fleet of gear is ready to hit the water again without delay.

Equipping your lake house guests with the proper gear transforms a good weekend on the water into an unforgettable one. By investing in durable, water-focused accessories, you protect both your guests and your peace of mind. Keep these essentials on hand, establish a solid post-lake routine, and enjoy the ultimate worry-free season on the water.
