Ask around for boat detailing prices and most of the answers come back as a rate per foot. That is a reasonable place to start. A 30-footer has more surface than a 20-footer. But two boats of the same length can end up with very different quotes, and the reasons are worth knowing before you compare numbers.
Why length is the starting point
Length is the one thing every owner knows without measuring, and it tracks roughly with surface area. It gives both sides a quick way to set a baseline. But surface area is not just length. A tall-sided cabin cruiser has far more topside than a low bowrider of the same length, and a flybridge adds a whole second deck to clean and protect.
So when a detailer asks about the type of boat as well as the length, they are not padding the quote. They are working out how much surface there really is.
What actually moves the number
1. Gelcoat condition
This is the big one. A hull that only needs a wash and wax is a short job. A chalky hull that needs compounding, polishing, and then protection can take several times as long. Heavy oxidation on a dark or colored hull takes the most time of all, because every step has to be done cleanly enough not to leave haze.
2. Where the boat is
A boat on a trailer in a driveway is the fastest to work on. A boat in a slip is slower for the same work, because the hull is only reachable from the dock side or a float, and heavier correction may not be practical in the water at all. Storage yards fall in between, depending on how much room there is around the boat.
3. Scope above the hull
Non-skid decks, vinyl seating, canvas and enclosures, carpet, stainless, and isinglass each add time. A quote for the hull only and a quote for the whole boat are different quotes, and it is worth knowing which one you are holding.
4. Waterline staining
A brown or yellow band along the waterline is mineral and tannin staining, and it needs its own chemistry and time. A light band is quick. A heavy band from a season in a lake or the Delta adds real labor.
5. Protection level
A coat of wax, a synthetic sealant, and a marine ceramic coating are three different price points, mostly because of the prep each one needs. A coating needs the gelcoat fully corrected and cleaned first, because it locks in whatever is underneath it.
6. How long since the last detail
A boat that gets maintained every season is predictable. A boat that sat uncovered for three summers is where the surprises come from: deeper oxidation, stains that have set, mildew in the vinyl seams. None of it is a problem, but it is time.
Two boats of the same length can be a half-day job and a three-day job. The tape measure does not tell you which.
Why we do not publish a price list
A per-foot rate looks simple until the boat shows up. Then it either turns into a starting rate with add-ons, or it gets quietly raised to cover the worst case. We would rather look at the actual boat and give you one number that holds.
The photos that get you a real quote
You do not need a site visit for most boats. Five photos in daylight usually cover it:
- A full side view so we can see the length, the height of the topsides, and the type of boat.
- A close shot of the sunniest side of the hull, where oxidation is worst.
- The waterline, close enough to see any staining.
- The deck and cockpit, including seats and any canvas.
- Where it is parked or tied up, so we know how we will reach it.
A palm wipe photo helps too. Rub your hand across the hull and take a picture of your palm. If it comes away white, we know before we arrive that this is an oxidation job.
Comparing quotes
If you are holding two boat quotes that look far apart, check three things before deciding: whether both include compounding or only waxing, whether both cover the deck and interior or only the hull, and what protection goes on at the end. Most of the gap between two honest quotes lives in those three lines.
Send us the photos and what you want done. You will get a fixed number for that boat, and if the cheaper option will do the job, we will say so.
