Why small craft age faster than the yacht they serve
A tender lives a harder life than almost anything else on the owner's list of toys. It is lowered and raised, loaded with people and gear, run through chop, pulled onto sand or concrete ramps, tied alongside seawalls, and left in the sun on davits or a swim platform lift. It has less protective coating than the yacht, often gets less attention, and takes more abuse per hour of use. A jet ski is similar, with the added problem of a hull that sits in warm salt water for long periods and an engine compartment that is closed to casual inspection.
In South Florida, ultraviolet light and heat are the main enemies. Surfaces that face the sky, such as tube tops, console tops, seat tops and rubber trim, fade, chalk and crack long before the surfaces underneath do. Salt crystals build up in every crevice and, if left, work into stainless fasteners, hinges, steering parts and trim rings. Mildew grows in seat seams and in the crevices where tubes meet floors. Sunscreen, fuel, oil and sunblock rub off on seat covers and leave marks that are harder to remove the longer they sit.
A regular detail on small craft is not a luxury. It is one of the simplest ways to prevent material loss, since a faded and chalky inflatable tube loses its protective outer layer and a cracked jet ski seat leaks water into the foam beneath. Cleaning and protecting these craft on a schedule keeps them usable for longer and keeps them looking right alongside the yacht they belong to.
Hypalon and PVC tubes need different handling
Rigid inflatable boats and soft inflatable tenders use tubes made of one of two common fabrics. Hypalon, a synthetic rubber coating on a fabric base, is traditionally more resistant to sunlight, fuel and chemicals. PVC, a plastic coating on a fabric base, is lighter and often less expensive, and many modern tubes are made with it. The two materials behave differently, and so do the cleaners and protectants that suit them.
Hypalon tolerates a wider range of cleaners, but it can chalk with age, and chalking is not dirt. It is the outer surface oxidizing and breaking down. Cleaning removes the chalk, polishing can restore some appearance, and protectant can slow further damage. PVC is more sensitive to strong solvents and to some silicone-based products. It can soften, discolor or lose flexibility with the wrong chemical, and it often gets a soft, cloudy appearance when it ages in the sun.
The first task on any inflatable is to identify the material. If the owner or captain knows the maker and model, that is usually enough. If not, the detailer looks at the tube's texture, seam construction and any labels, and starts with the gentlest method on a hidden spot. The page on cleaning inflatable boats and dinghies covers the tube care in more depth, and this page concentrates on the whole craft.
Gelcoat and fiberglass on the tender hull and console
Many tenders have a rigid fiberglass hull under the tubes, and many jet skis have a gelcoated or painted hull and body. These surfaces behave like the gelcoat on a larger vessel, though they are smaller, more curved and often more heavily used. They oxidize, stain, pick up scuffs from docks and ramps, and show waterline residue where they sit in the water.
Careful work begins with a fresh water wash and a mild boat soap, to remove salt and loose soil without scratching. Stains from algae, rust or fender marks are treated with the appropriate cleaners after a test spot. If the gelcoat has dulled, a light polishing step can bring back clarity, with a compound only where the surface needs it. The principles are the same as in the page on compounding and polishing, scaled to a smaller surface where heat from the machine builds up quickly and edges are close.
After polishing, a protective layer, such as wax or a synthetic sealant, gives the surface something to wear instead of the gelcoat itself. On a jet ski that sits on a lift in direct sun, protection wears faster than on a yacht that is covered most of the time, so the maintenance interval is shorter.
The salt rinse habit and what it prevents
Nothing protects a tender or jet ski better than a fresh water rinse after use. Salt left to dry on a surface forms crystals, and those crystals attract moisture from the humid air, keeping fittings damp and corrosion going long after the craft has left the water. A quick rinse with a hose, with attention to hinges, cleats, steering parts, engine cooling flush ports where the manufacturer allows, and the inside of seat lids, prevents most of the buildup.
A detailing crew cannot be there after every outing, but it can help the owner or captain put a routine in place. The simplest routine is a rinse, a wipe of the console and screens, a quick check that drain plugs are in the right position, and a cover or lift storage in a place that drains. That routine, practiced consistently, makes each professional detail much easier, since the crew starts with a craft that is mostly clean.
The guide on rinsing after saltwater use goes through the order of rinsing and the places where salt hides on a boat. Most of it applies directly to tenders and jet skis, with the extra caution that engine flush procedures should follow the maker's instructions, not a detailer's habit.
Storage on lifts, davits and swim platforms
How a tender is stored shapes how it ages. A tender on a swim platform or in a garage space is partly sheltered, and a tender on davits is exposed to sun and spray. A jet ski on a lift above the water is exposed on every surface, while one in the water collects growth on the hull and drains the owner's patience at the dock. Each arrangement leads to a different pattern of wear and a different cleaning problem.
Craft stored on lifts dry out in the sun, so the top surfaces take the damage. Craft left floating gather marine growth below the waterline, and the waterline itself picks up a stained band. Craft stored under a cover can trap moisture and develop mildew if the cover is not breathable or the craft was put away wet. Craft stored on trailers can pick up road grime and brake dust, and the tires and trailer frame carry salt corrosion.
A good detail takes the storage method into account. For a lift-stored jet ski, the focus is on UV protection for seats and trim, with a regular rinse routine. For a floating tender, the focus is on waterline stains, and on checking the hull for growth. For a davit-stored tender, the attention goes to the places where the lifting slings and straps contact the tubes or hull, since those points rub and wear.
Seats, consoles, steering and the small parts
The surfaces people touch most on a small craft are seats, grab handles, steering wheels or handlebars, throttle controls and console tops. They collect sunscreen, hand oils, salt and sometimes fuel. They are also commonly made from marine vinyl, rubber, plastic and anodized or plated metal, each of which reacts differently to cleaners.
Marine vinyl seats are cleaned with a gentle soap solution and a soft brush, then rinsed and dried. Aggressive solvents, strong degreasers and bleach can strip the surface coating and speed up cracking. Faded vinyl can be restored only to a point, and sometimes the better choice is protection of what remains. The vinyl upholstery cleaning page explains what can and cannot be done, and the same rules hold on a jet ski seat.
Small metal parts such as cleats, hinges, steering links and trim rings are cleaned of salt, dried, and where appropriate treated with a suitable protectant. Plated metal can have thin plating that polishing wears through, and anodized aluminum can be dulled by the wrong product. A gentle approach and a quick test on a hidden spot make the difference. The detailer should not lubricate or adjust steering and throttle linkages, since those are mechanical systems for a marine technician.
Engine compartments and what a detailer will not touch
The engine compartment of a jet ski, and the outboard or small inboard engine of a tender, is a place where cleaning can go wrong. Water driven into electrical connections, ignition parts or air intakes can cause problems that show up later, sometimes days later, as a no-start or a rough running engine. Detailers who work on small craft learn to be careful here.
A reasonable detail treats the exterior of the engine cowling, wipes visible surfaces with a damp cloth, and avoids spraying water into the compartment. If the owner or captain wants the engine compartment cleaned, the better approach is a technician who understands the machine, and who can lift covers, disconnect what must be disconnected and clean with the right materials. A detailer should not guess.
The same is true of fuel-related residue. A small fuel stain on a hull or seat can be cleaned, but the cause should be reported. A leaking fuel line, a loose fitting or an overfilled tank needs a technician, and a detailer who sees fuel where it should not be should say so plainly.
Mildew, odor and the closed spaces of small craft
Small craft often have storage compartments, seat lids and console cavities that stay closed for weeks. In humid weather, those closed spaces trap moisture, and mildew follows. The smell is often the first sign, and it can be strong in a console that holds a damp life jacket or a towel.
Cleaning begins by emptying the compartment, so that what was stored can be washed or dried separately. The compartment surface is cleaned with a suitable mild cleaner, rinsed where it can be and dried thoroughly. Leaving lids propped open for a short time, where security and weather allow, helps. Moisture absorbers can help in closed boxes, though they are not a cure for a leak.
If mildew keeps returning in a compartment, there is usually a water source, such as a failed gasket, a leaking hatch or a drain that does not drain. That is something to fix at the source. The pages on mildew treatment and odor removal go into the approach for larger spaces, and the same reasoning applies on a smaller scale.
What a dockside tender and jet ski detail includes
A thorough visit usually starts with an inspection. The crew looks over the tubes or hull, the seats, the console, the hardware and any graphics, and notes the condition before touching anything. If the craft is on a lift, the crew checks the lift is secure and the craft is stable. If it is in the water, it is brought alongside and secured safely.
The work follows a sensible order. Loose debris is removed, the craft is rinsed with fresh water, and a mild soap is applied and rinsed. Tubes, hull and console are cleaned according to their material. Stains are treated where needed. Seats and trim are cleaned and conditioned with products suited to them. Metal parts are cleaned and protected. Glass or acrylic windshields are cleaned with materials that do not scratch them. The craft is dried by hand to avoid water spots.
Protection comes last. UV protectant goes on tubes and vinyl according to the material. Wax or sealant goes on gelcoat or paint. Graphics are checked, and the page on hull graphics and decal care covers how to protect them. Finally, the crew notes anything that needs another trade, such as a leaking valve, a chafed tube seam, a cracked seat base or worn steering parts.

Keeping small craft in step with the yacht
It is common to see a beautifully maintained yacht with a faded, chalky tender on the davits. The contrast is obvious, and it affects how the whole vessel is judged, whether by guests, brokers or a surveyor. Including the tender and any jet skis in the regular detailing plan keeps the whole package looking consistent.
It also helps resale. When a yacht is sold, the tender is part of the sale, and its condition influences how buyers view the care the owner has given to everything else. The guide on protecting yacht resale value covers the thinking behind this in more detail.
To plan a visit for your tender, RIB or jet ski, call. Have the make and model if you know them, how the craft is stored, and any problems you have noticed, such as chalking, cracks, stains or odor. Quotes are given by phone, and a more complicated job may need an on-site visit first, with a service call charge explained before dispatch.
Questions people ask
Can you detail a tender that is on davits or a lift?
Yes, as long as the craft is secure and the lift or davit system is stable. The crew works around the support points and checks the contact areas where straps or slings touch the tubes or hull. If the craft needs to be lowered for access, that is arranged with the captain or owner first, so nothing is moved without approval.
How do I know if my inflatable tubes are Hypalon or PVC?
The maker and model usually answer it. If you do not know, the detailer checks labels, seam style and surface texture and begins with the gentlest method on a hidden spot. Treating PVC like Hypalon can soften or discolor it, so identifying the material first is a basic step.
Will you clean inside the engine compartment of a jet ski?
A detailer wipes exterior and visible surfaces but does not spray water into engine compartments or touch electrical parts. Water in the wrong place can cause problems later. If the engine bay needs cleaning, a marine technician who understands the machine is the right person, and the detailer will tell you what was seen.
Why do my seat covers keep fading and cracking?
Sun, heat, salt and sunscreen all attack marine vinyl. Regular rinsing, gentle cleaning and UV protection slow the process, but vinyl that has already cracked cannot be repaired by detailing. A cover or lift storage that limits direct sun helps, and the detailer can advise on realistic expectations after seeing the condition.
Should the tender be detailed with the yacht or separately?
Usually together, since the crew is already on site and the finished vessel looks consistent. Some owners prefer a separate visit when the tender is stored elsewhere, such as a lift at a private dock. Either way, the same care applies, and the visit can be planned around how the craft is stored.
How are quotes handled for small craft?
Quotes are given only by phone. Simple jobs can often be discussed from a description, while heavily weathered or damaged craft may need an on-site look first. There is a service call charge, and it is explained on the phone before anyone is dispatched, so you know what to expect.
