8 Saltwater-Safe Clothes and Gear for Your First Catamaran Excursion

Stepping onto a catamaran for the first time brings an unmatched rush of excitement as the dual hulls lift and slice through open water. Unlike a standard monohull, these wide, stable platforms invite more movement, faster speeds, and a unique spray pattern that will leave unprepared passengers soaked. Bringing the wrong gear to this saltwater environment guarantees discomfort, but the right clothing and equipment will keep the focus entirely on the adventure ahead.

What to Expect on Your First Catamaran Excursion

Catamarans offer a surprisingly stable ride compared to traditional sailboats, but their speed and wide beam create a different set of physical demands. The trampoline—the netted area between the hulls—is a prime spot for relaxation, but it is also highly exposed to wind, sun, and upward spray. Because these boats sit relatively low to the water and travel fast, salt spray is a constant companion rather than an occasional splash.

Movement on deck is constant, requiring quick steps across wet fiberglass and netting while holding onto slick stainless steel shrouds. The wind feels stronger because the boat moves quickly, making temperature regulation a puzzle of hot sun and cool, wet drafts. Understanding this dynamic helps explain why everyday casual wear falls short on a multihull cruise.

Sailing Gloves – Gill Championship Gloves

Handling wet lines, adjusting rigging, or even just holding onto cold, salty handrails can shred bare skin in minutes. Sailing gloves provide the necessary grip to manage high-tension ropes without risking painful friction burns or losing hold when a sudden gust catches the sails. They act as a critical barrier between delicate skin and abrasive, salt-encrusted marine hardware.

Gill Championship Gloves are the industry standard for recreational sailors because of their Dura-Grip fabric on the palm, which delivers incredible wet grip without sacrificing flexibility. The short-finger design leaves fingertips free for tying knots or operating touchscreens while protecting the knuckles and palms from heavy friction. Double-stitched seams and a contoured wrist closure keep them secure when drenched.

• Key Specs: Dura-Grip palm protection, 4-way stretch fabric, UV 50+ protection
• Best Uses: Active line handling, driving the helm, gripping wet handrails
• Size Options: XS to XXL in unisex fit

When buying, note that these gloves fit snugly to prevent bunching; sizing up is wise if measurements fall between sizes. They require a quick freshwater rinse after every outing to prevent the salt from stiffening the material over time. These gloves are ideal for anyone active on deck but are unnecessary for passengers who plan to sit purely in the cabin or cockpit.

Deck Shoes – Sperry Sea Kite Sport Moc

Wet fiberglass is incredibly slick, and standard sneakers can turn a simple walk across the deck into a slipping hazard. Deck shoes must provide reliable traction on wet, angled surfaces while protecting toes from stubbing on heavy deck hardware like cleats and tracks. Furthermore, boat owners expect non-marking soles to prevent unsightly black scuffs on pristine white gelcoats.

The Sperry Sea Kite Sport Moc excels because of its Adaptive Wave-Siping on the rubber soles, which channels water away from underfoot to maintain a solid grip on wet decks. Built with water-resistant leather and mesh panels, they dry quickly and allow feet to breathe during hot afternoon sails. A molded EVA midsole provides substantial arch support, reducing the fatigue that comes from standing on a moving vessel for hours.

• Key Specs: Adaptive Wave-Siping non-marking soles, water-resistant leather/mesh upper, removable compression-molded EVA footbed
• Best Uses: Wet deck navigation, active sailing, casual coastal walking
• Size Options: Men’s 7 to 15 (including wide widths)

Users should wear these without socks or with synthetic, quick-drying socks, as cotton will trap moisture and cause blistering. While highly durable, they should not be worn on asphalt or gravel, as rough ground wears down the specialized soft rubber siping designed for boat decks. They are perfect for active passengers who need a secure footing but are overkill for casual beachgoers who prefer bare feet.

Dry Bag – Sea to Summit Big River Dry Bag

Catamaran excursions involve constant exposure to water, whether from salt spray over the bow, a sudden rain squall, or dripping gear. Keeping phones, cameras, car keys, and dry change-of-clothes safe requires a dedicated barrier that keeps water out even when submerged. Standard backpacks will soak through quickly, ruining sensitive electronics with corrosive saltwater.

The Sea to Summit Big River Dry Bag is built from 420D nylon fabric with a TPU lamination, making it incredibly puncture-resistant and completely waterproof. Unlike flimsy dry bags, this model features heavy-duty lash loops that allow it to be securely strapped to the catamaran’s trampoline or stanchions during rough transits. The roll-top closure seals tight, while the white interior laminate makes finding small items at the bottom easy.

• Key Specs: 420D waterproof nylon, TPU laminate interior, heavy-duty lash loops
• Capacity Options: 5L, 8L, 13L, 20L, 35L, 65L
• Best Uses: Protecting electronics, storing dry clothes, organizing deck gear

Properly sealing the bag requires rolling the top down at least three times before buckling; rushing this step compromises water resistance. It is a rugged, relatively stiff bag, meaning it does not pack down as small as ultra-lightweight dry sacks. This is the ultimate choice for those carrying expensive cameras or spare layers, though casual riders with only a smartphone might prefer a simple waterproof phone pouch.

Polarized Sunglasses – Costa Del Mar Fantail

The glare of the sun reflecting off saltwater is blinding and can cause severe eye strain, headaches, and temporary vision loss. Polarized sunglasses are essential on a catamaran because they filter out this horizontal glare, allowing the wearer to see through the surface to spot shallow reefs, sandbars, and marine life. They also shield eyes from wind-blown salt spray and harmful UV radiation.

Costa Del Mar Fantail sunglasses feature 580G light-stabilizing glass lenses, which provide unmatched clarity and scratch resistance in harsh marine environments. The heavy-duty nylon frames are co-molded with Hydrolite rubber along the temples and nose pads, preventing them from slipping off when sweating or facing strong winds. These glasses block yellow light to enhance color definition, making shallow water transitions incredibly clear.

• Key Specs: 580G polarized glass lenses, bio-resin frames, Hydrolite rubber nose/temple pads
• Best Uses: Offshore navigation, fish spotting, bright-sun eye protection
• Frame Fit: Medium-sized sport wrap

Because these use real glass lenses, they are slightly heavier than plastic alternatives and will sink rapidly if dropped in the water. Pairing them with a floating retainer strap is non-negotiable to prevent a costly loss over the side. They are an indispensable tool for anyone steering the vessel or spotting obstacles, though budget-conscious travelers might find them too pricey for a single trip.

Sun Hoodie – Patagonia Tropic Comfort Hoodie II

Spending hours under the blazing sun with no shade on a catamaran deck is a recipe for severe sunburn. Sunscreen washes off with sweat and salt spray, making a lightweight, high-UPF garment the most reliable defense against UV rays. A sun hoodie covers the arms, torso, neck, and ears without trapping body heat on humid days.

The Patagonia Tropic Comfort Hoodie II is crafted from ultra-lightweight polyester fabric that boasts a UPF 50+ sun protection rating. The generous hood is designed to fit easily over a baseball cap, shielding the sides of the face and neck from angled sun rays. Thumb loops keep the sleeves locked down over the backs of the hands, protecting a highly vulnerable area that is often forgotten during sunscreen application.

• Key Specs: 100% recycled polyester jersey, UPF 50+ rating, HeiQ Fresh durable odor control
• Best Uses: Hot weather deck protection, beach landings, tropical fishing
• Size Options: XS to XXL in relaxed fit

The fit is purposely loose to encourage airflow, so those who prefer a skin-tight athletic fit may want to size down. The fabric can catch on sharp rigging or Velcro closures if care is not taken during movement around the deck. This is a must-have piece for anyone spending a full day on the water, but it is not necessary for those who plan to stay inside the cabin.

Sailing Shorts – Helly Hansen Crew Shorts

Regular cotton shorts become heavy, wet, and chafing messes when splashed with saltwater, taking hours to dry. Sailing shorts must withstand sliding across non-skid fiberglass decks while offering quick-drying performance and secure pockets for personal items. They act as a durable shield for your thighs when sitting on rough, hot surfaces.

Helly Hansen Crew Shorts are constructed from a durable, quick-dry stretch polyamide, allowing for unrestricted movement when climbing around the catamaran. The fabric features a water-repellent treatment that causes light spray to bead up and roll off rather than soak in. Large, secure cargo pockets offer ample storage for small tools or keys, keeping them close without interfering with a harness or life jacket.

• Key Specs: Stretch polyamide fabric, DWR (Durable Water Repellent) finish, UPF 40+ rating
• Best Uses: Active deck work, dinghy transfers, warm-weather coastal cruising
• Size Options: Waist sizes 28 to 40

These shorts do not include an inner liner, so they must be paired with comfortable, moisture-wicking underwear to prevent chafing during long days on the water. The sizing can run slightly athletic, making it wise to check the size chart carefully before purchasing. They are perfect for active passengers who need utility and durability, but too rugged for those looking for casual swimwear.

Sailing Jacket – Gill OS3 Coastal Jacket

Even on warm days, sailing at high speeds into a headwind creates a significant chill, especially when wet with salt spray. A sailing jacket provides a windproof and waterproof outer shell that keeps core body temperatures stable when weather conditions deteriorate. It serves as the primary barrier against heavy downpours and cold ocean drafts.

The Gill OS3 Coastal Jacket features two-layer XPLORE waterproof and breathable fabric designed specifically for harsh marine conditions. The high-cut thermal collar offers excellent face protection, while adjustable outer cuffs with polyurethane inner seals block water from running up the sleeves when working overhead. It is lightweight enough for warm-weather squalls but roomy enough to layer over a fleece when temperatures plunge.

• Key Specs: 2-layer XPLORE waterproof fabric, high thermal collar, adjustable double cuffs
• Best Uses: Squall protection, cool evening sailing, coastal cruising
• Size Options: XS to XXL

Keep in mind that this is a shell jacket designed for wind and water protection, meaning it does not have built-in insulation. To stay warm in cold climates, it must be paired with mid-layers like fleece or technical wool. This is an essential investment for offshore or coastal catamaran trips, but may be overkill for short, sunny harbor cruises.

Marine Binoculars – Steiner Navigator 7×50

Navigating a catamaran requires keeping a sharp lookout for distant markers, shallow reefs, other vessels, and marine wildlife. Normal land-based binoculars are useless on a moving deck because their high magnification magnifies the boat’s motion, making it impossible to focus. Marine binoculars utilize specific magnification and lens configurations to deliver stable, bright images on rolling seas.

The Steiner Navigator 7×50 is the gold standard, offering a 7x magnification that minimizes image shaking on unstable water. The massive 50mm objective lenses pull in incredible amounts of light, making them highly effective during twilight or fog. Its rugged Makrolon housing is nitrogen-filled to prevent internal fogging and can withstand submersion up to five meters in saltwater.

• Key Specs: 7x magnification, 50mm objective lens, Sports-Auto-Focus system, waterproof to 16 feet
• Best Uses: Navigation, hazard spotting, wildlife viewing, low-light observation
• Includes: Neoprene carrying strap, rain protection cap, objective covers

These binoculars are heavy and require a floating strap to ensure they do not sink to the bottom if dropped overboard. Their high-end optics make them a serious financial investment, though they will last a lifetime with proper care. They are vital for the vessel’s navigator or avid wildlife watchers, but unnecessary for casual guests who just want to relax.

Why Saltwater Requires Specialized Marine Gear

Saltwater is one of the most destructive natural forces on the planet, capable of degrading materials that easily survive freshwater environments. When saltwater evaporates, it leaves behind microscopic salt crystals that act like sandpaper, wearing down fabric fibers and causing premature tearing. These crystals also jam zippers, seize metal snaps, and cloud standard optical lenses.

Specialized marine gear is designed with non-corrosive materials like marine-grade plastics, treated stainless steel, and bronze. Fabrics are treated to resist salt absorption, and zippers are oversized with plastic teeth to prevent salt crust from locking them up. Investing in marine-specific gear ensures that your equipment will actually function when you need it most, rather than failing after a single exposure to ocean air.

How to Clean and Store Gear After Ocean Use

The secret to making marine gear last for years lies entirely in how it is treated after returning to the dock. Fresh water is the ultimate antidote to saltwater damage. Every piece of clothing, footwear, and equipment must be thoroughly rinsed with clean, fresh water as soon as possible to dissolve and wash away salt residues.

Once rinsed, gear should be air-dried in a shaded, well-ventilated area rather than left in direct sunlight, which can break down UV-resistant coatings. Ensure zippers are worked back and forth while rinsing to clear any trapped particles. Store your clean, dry gear in a cool, dark closet; never pack wet items into airtight containers, as this invites mold and mildew growth.

Critical Safety Gear to Double Check Before Departure

No matter how advanced your personal gear is, basic safety equipment must always take priority before the catamaran leaves the slip. First and foremost, ensure there is a USCG-approved Type I or Type II PFD (Personal Flotation Device) for every passenger, and that they fit correctly. Inspect the inflation mechanisms on automatic life jackets and check that whistle and light attachments are functional.

Confirm that the vessel has a working VHF marine radio and a backup handheld radio to secure communication with the Coast Guard or local marinas in an emergency. Double-check the location of the flares, fire extinguishers, and a fully stocked marine first aid kit. Finally, make sure everyone onboard knows where the throwing devices, such as life rings or throw bags, are stored so they can be deployed instantly if someone falls overboard.

Conclusion

Preparing for a catamaran excursion requires a smart balance of comfort, functionality, and rugged durability. Investing in saltwater-safe gear ensures that unpredictable marine environments remain thrilling rather than exhausting. With the right equipment secured, the open ocean is yours to explore with complete peace of mind.
