Salt, sun, and season after season on Long Island water are brutal on gelcoat and canvas. We restore, protect, and maintain your boat right at the marina, your driveway, or the yard.
Nobody's boat has an easy life on Long Island. The Great South Bay, the Sound, and the ocean deliver a constant assault of salt spray, UV, bird droppings, waterline scum, and dock rash — and every season it shows a little more: gelcoat goes chalky, metal pits, canvas mildews, vinyl yellows and cracks. A boat that isn't regularly detailed doesn't just look tired; it's actively losing value and structural surface protection every month it sits.
NextGen's marine detailing crews come to your boat — at the marina, in your driveway, on the trailer, or at the storage yard — with everything needed to reverse that clock: compounds and polishes for oxidation removal, marine waxes and sealants, interior extraction equipment, and mildew treatment for canvas and upholstery. From a mid-season wash-and-wax to a full oxidation restoration on a neglected hull, we bring the boat back and then keep it there.
We detail every kind of vessel on Long Island water: center consoles and fishing boats, bowriders and cruisers, sailboats, pontoons, jet skis and PWCs, and yachts. Hull and topside, cockpit and cabin, canvas, isinglass, brightwork, and trailers — the whole boat, done properly.
Gelcoat is your boat's skin, and Long Island sun and salt eat it in a predictable sequence: first gloss loss, then chalking oxidation, then porous gelcoat that stains permanently and eventually requires professional wet-sanding or painting to fix. Wax and sealant are what interrupt that sequence — a protected hull sheds salt and UV; an unprotected one absorbs them. The visible difference between a five-year-old boat that's been maintained and one that hasn't is dramatic; the resale difference runs into thousands of dollars on even modest boats.
Interiors carry their own clock. Marine vinyl cracks when it bakes in the sun unprotected; canvas and isinglass cloud and mildew in Long Island humidity; carpet and upholstery in a closed cabin brew the musty smell every used-boat shopper recognizes instantly. Regular professional cleaning, conditioning, and mildew treatment keeps all of it serviceable for years longer — and keeps your boat the one at the dock people compliment, not the one they politely ignore.
We inspect gelcoat condition, oxidation level, metal, canvas, and interior with you, then quote the right package firm — restoration and maintenance are different jobs, priced honestly.
Full topside and hull wash with marine-safe soaps, waterline scum and exhaust staining treated, bird droppings and salt residue removed from every surface.
Chalky, dull gelcoat is machine-compounded and polished back to gloss — light single-stage correction through full heavy-oxidation restoration, as the hull requires.
Premium marine wax or polymer sealant is applied to hull and topsides, locking in the gloss and shielding the gelcoat from salt and UV for the season.
Vinyl cleaned and UV-conditioned, carpet and upholstery extraction-cleaned, cabin surfaces detailed, storage compartments cleaned out and deodorized.
Stainless and aluminum polished, canvas and isinglass cleaned and treated, non-skid scrubbed — then a full walkthrough with you before we call it done.
That dull, powdery finish is UV-burned gelcoat. Machine compounding removes the dead layer and polishing restores the gloss — the transformation on a neglected hull is the most dramatic before-and-after in detailing.
The brown 'mustache' at the bow and scum line along the hull are mineral and organic staining that soap won't touch. Marine-specific removers dissolve them cleanly without harming the gelcoat.
Long Island humidity turns closed boats into mildew farms. We kill and remove mildew from canvas, cushions, and cabin surfaces, treat to slow its return, and get rid of the musty smell at the source.
Hazy enclosure windows and pitted rails age a boat instantly. We clean and polish isinglass with the correct products (never dry-wiping scratches into it) and machine-polish metal back to bright.
A boat that looks the way you picture it when you think about the season — deep gloss on the hull, bright metal, clear enclosures, a cabin that smells like nothing. Underneath the looks: gelcoat that's protected instead of eroding, vinyl that stays supple, canvas that lasts more seasons, and a vessel whose survey-day and sale-day condition is being actively preserved. On Long Island's boat market, condition is value — detailed boats sell faster and for more, every time.
And because we're mobile, none of it costs you a haul-out or a Saturday. We work at your slip, your driveway, or your storage yard, on your schedule — including spring commissioning details to start the season right and end-of-season details before winterization, when cleaning off a summer of salt and grime matters most. Guaranteed work, firm quotes, and a crew your dockmates will ask about.
Marine detailing on Long Island is typically priced per foot: maintenance wash-and-wax packages generally run $15–$25 per foot, full details with single-stage polish $25–$45 per foot, and heavy oxidation restoration $45–$75+ per foot depending on condition. Interior-only and cabin deep cleans are quoted by vessel size and state. A 24-foot center console full detail typically lands in the $700–$1,000 range; exact numbers come from seeing the boat.
Every quote is firm after assessment — no per-foot bait rates that balloon dockside. Seasonal maintenance plans (monthly or biweekly wash programs plus scheduled details) earn preferred pricing and keep the boat permanently ready. Call (631) 490-4703; new customers save 10% with code NEW10.
We service boats across all of Long Island — South Shore marinas from Freeport to the Hamptons, North Shore harbors on the Sound, Fire Island ferries' backyards, and every driveway and storage yard in between.

Marine detailing punishes shortcuts. Automotive products on gelcoat underperform and don't last in salt. Aggressive compounding by inexperienced hands burns through gelcoat edges. Dry-wiping isinglass scratches it permanently. And the guy with a bucket at the marina charging half price typically delivers half a job — wash and wax over oxidation that needed correction, gone by August.
NextGen runs marine-specific products and processes, machine correction matched to actual gelcoat condition, and crews trained on the surfaces boats are made of — gelcoat, isinglass, marine vinyl, canvas, teak, stainless. We assess honestly (not every hull needs a restoration; some genuinely do), quote firm, and guarantee the result. Boat owners talk on the dock; our 5.0 rating and the boats we maintain are the marketing.
