Boat Detailing Cost per Foot: Every Tier

Boat detailing cost is quoted per foot of boat length, but the foot is only the multiplier — the tier sets the rate, from a few dollars a foot for a wash to above $100 for restoration. One honesty note before any numbers: no government, BoatUS or Discover Boating per-foot benchmark for detailing exists. Every band here is triangulated from working detailers' published price lists, not industry statistics, and where the lists disagree, the disagreement is printed rather than averaged away.

Boat Detailing Cost per Foot: the Price Table

Read the table as published bands, not quotes. Catalyst Marine Services' 2026 cost guide prices by gelcoat condition, Salty Mountain's pricing page by named package, and Dockside Detailing's price guide splits its full detail into three condition grades — three structures landing in overlapping bands, each row's spread reflecting real disagreement.

Every figure is unpacked, list by list, below, because inclusions decide whether two quotes at the same rate are the same job. Rather compare boats than bills? The boat listings on Boat Deals Direct are priced by the boat.

Basic Wash and Wash-and-Wax: What's Included

A basic wash buys cleaning only: hull sides and topsides washed, deck and non-skid scrubbed, rinse and dry, glass wiped — no protection applied: the cheapest, least consistently priced tier. Catalyst puts recurring wash and maintenance from about $7 a foot, a full-service wash around $10. Salty Mountain does not price it per foot at all: a flat $125 at any length serviced, near $7 a foot on an 18-footer, nearer $4 on a 30-footer. Dockside also sells its basic exterior wash as flat packages, $179–$279. Triangulated, a basic wash sits at about $5–$15 a foot — a band reflecting two pricing models, not one rate.

Wash and wax adds the protective layer: wash and decontamination, then wax or sealant over the gelcoat. Salty Mountain lists $17 a foot; Dockside lists exterior wash and wax at $19 a foot, or wax alone as a $12-a-foot add-on. Both sit inside the published $15–$30-a-foot band; larger boats, heavier grime and sealant instead of basic wax push toward its top.

Full Detail, Line by Line

A full detail is the wash-and-wax scope plus the interior. The published inclusions run: exterior wash and protection; interior vacuum and wipe-down; vinyl cleaned and conditioned; compartments and lockers cleaned; flooring and glass cleaned; metal and stainless polished; motor cowling wiped down — and, on Salty Mountain's $22-a-foot full detail, the trailer.

The spread is the widest of the standard tiers because "full" is graded differently. Salty Mountain charges one rate, $22 a foot. Dockside grades by condition — Refresh Detail $18–$24 a foot, Standard Full Detail $24–$34, Heavy Full Detail $34–$50 or more — so a neglected boat crosses the top of the $20–$45-a-foot band while a maintained one sits at the bottom. Catalyst sells no named full detail per foot at all; its jobs are priced by the correction the gelcoat needs, full-boat scope built in. Same tier name, three structures: compare inclusions before rates.

Oxidation Correction, Polishing and Wet-Sanding

Here detailing becomes finish restoration, and the money jumps. Light polish — machine polishing a finish dull or swirled but not oxidised — runs $35–$60 a foot at Catalyst. Salty Mountain's light oxidation removal, a one-step compound, is $30 a foot, just below that band: the lists use "polish" and "light oxidation" for overlapping work and price it apart, printed here, not split into a false midpoint.

Chalky gelcoat — white residue on a hand — needs correction: compound cutting the dead layer away, then polish, then protection. Catalyst prices it at $50–$75 a foot; Salty Mountain's heavy oxidation removal, a two-to-three-step compound and polish, is $55 a foot, inside the same band. Dockside publishes no per-foot correction rate: oxidation removal there is a $500 minimum for hull sides, quoted by condition and length, topside correction extra.

Past chalky sits restoration. Catalyst's deepest finish work, correction plus a jeweling pass, runs about $100 a foot; gelcoat needing wet-sanding first is quoted in person, no published rate. Restoration therefore occupies roughly $75–$140 or more a foot, the top set by quote-only jobs — nobody honest publishes a firm rate sight unseen.

Ceramic Coating for Boats: Cost and Whether It Pays

Marine ceramic is the premium protection tier, applied over gelcoat already washed, decontaminated and — if needed — corrected, because coating over oxidation seals the problem in. Salty Mountain lists ceramic at $85 a foot. Catalyst prices ceramic added onto a correction at $75–$125 a foot, and a standalone re-coat on a finish already in shape at $75. The triangulated band is about $75–$125 a foot — with a catch: Catalyst's correction and ceramic as one job runs $175–$250 a foot combined, so the coating is rarely the whole bill.

Whether it pays is a lifespan question, and the lists disagree there too: Catalyst states 12–24 months in salt and sun; Salty Mountain states a realistic 12–18 months, regardless of bottle claims. Against that, wax holds roughly 2–4 weeks in summer heat at Catalyst, a polymer sealant 3–6 months. Ceramic pays when you keep the boat long enough to replace seasons of wax-tier spending with one coating cycle, and when the correction beneath it was needed anyway. On a boat you may sell within a season, the arithmetic rarely closes.

What Raises the Price

Five drivers move a boat inside — or out of — its band. Condition is the largest: oxidation is the difference between a $22-a-foot full detail and a $50–$75-a-foot correction on the same hull. Dark gelcoat costs more to correct than white, showing every swirl. Layout counts alongside length: cabin, flybridge, tower and extensive stainless add hours an open center console lacks. Add-ons stack quietly — Salty Mountain prices hard-water spot removal at up to $10 a foot extra; Dockside prices heavy interior work and scum-line removal from $125 each. And how a boat is kept between details decides how much correction it needs — the exposure side is priced in our boat storage cost breakdown.

DIY vs Hiring a Detailer

The DIY bill is real money plus time: polisher, pads, compound, polish, wax or sealant and wash products — a few hundred dollars of kit before the first boat — against the per-foot rates above. On the wash tiers that trade favours the owner: the work is cleaning, and kit cost spreads over seasons. Which tasks fall due when is a schedule question, covered by our boat maintenance checklist — this post prices the work; that one calendars it.

The trade reverses at correction and ceramic. Gelcoat is a finite layer: a rotary polisher in untrained hands can cut through it, converting a $50–$75-a-foot correction into a gelcoat repair no detail price covers. Ceramic assumes a properly prepared surface, and a failed application means paying for the prep twice. Hire out the tiers where a mistake is permanent; price the consumable tiers against your own time.

How Often Should a Boat Be Detailed?

Frequency is a cost question because protection expires on a calendar. A wax tier lasting weeks in summer sun implies several wash-and-wax visits a season; a sealant lasting 3–6 months implies roughly two; ceramic lasting 12–24 months converts the spend into washes plus one coating cycle. Two full details a year — start of season and before storage — is Salty Mountain's described pattern: $44 a foot a year at its $22-a-foot rate, before any correction. A pre-sale detail is weighed against asking price instead — the trade-off is worked through in our how to sell a boat guide; here, one full detail is usually the cheapest line in a sale budget.

Boat Detailing Cost FAQs

How much does it cost to detail a 25-foot boat?

Multiply the tier by 25. At the published bands: wash and wax at $15–$30 a foot is roughly $375–$750; a full detail at $20–$45 is roughly $500–$1,125; oxidation correction at $50–$75 is roughly $1,250–$1,875; ceramic at $75–$125 is roughly $1,875–$3,125, usually on top of correction.

Why do detailers quote such different prices for the same boat?

Because tier names are not standardised. One list sells a basic wash as a flat $125, another prices washes per foot; one full detail is a single $22-a-foot rate, another is three condition grades to $50 or more a foot. A rate means nothing without its inclusion list — compare coverage before cost.

Is ceramic coating worth it on a boat?

Over time, it can. At $75–$125 a foot it costs several times a wax tier, but published lifespans of 12–18 and 12–24 months replace repeated wax spending across seasons. It pays on a boat you keep; rarely on one about to be sold, or over gelcoat still needing paid correction.

Does a detailer charge more for an oxidised boat?

Yes — oxidation is the biggest price driver on every list. A maintained boat buys cleaning tiers; a chalky boat buys correction at $50–$75 or more a foot, and a heavily oxidised boat may be quoted in person only — remaining gelcoat decides the job.

Bottom line: boat detailing cost is a tier price before a length price — about $5–$15 a foot to wash, $20–$45 to fully detail, $50–$75 or more to correct, $75–$125 for ceramic.
