Boat Bottom Painting in Sag Harbor
Most owners find out what bottom paint really costs the day the yard calls and says the old coating has to come off first. Boat bottom painting in Sag Harbor is one of the few marine jobs where the quote you get on the phone and the bill you get at the end can be a thousand dollars apart, and the reason is almost always the same: nobody asked what was already on the hull. At Yacht Hampton Boating Club and Marina, our labor rate is $500 plus material for boats under 25 feet, and we will look at what is on your bottom before we quote you, not after. Call or text 631-500-7777.
The Question That Decides Your Bill
There are two families of antifouling paint, and the one already on your hull controls what happens next.
Ablative paint
Ablative coatings wear away slowly as the boat moves, exposing fresh biocide underneath. More coats means more seasons before you repaint. For a boat that gets used regularly out of Peconic and Noyac Bay, ablative usually makes sense, because the paint works while the boat works.
Hard paint
Hard paint stays put and leaches biocide through a porous surface. It does not wear off, which sounds like an advantage until you have five seasons of it built up. At that point the buildup has to be stripped before anything new goes on.
The rule that costs people money
You can put ablative over hard. You generally cannot put hard over ablative without stripping first. That single sentence is the difference between a routine repaint and a full strip job, and it is the reason we ask what is on your hull before we give you a boat bottom painting quote. If you do not know, we can look at it when we haul you.
What Boat Bottom Painting Costs at Our Marina
Under 25 feet
$500 labor plus material. Material is quoted separately and we tell you the cost before we start, not after we have opened the cans. A gallon of quality antifouling runs well into the hundreds, and how many gallons your boat needs depends on length, beam, and how thirsty the old coating is.
Over 25 feet
Written quote. Surface area does not scale in a straight line with length, and neither does paint volume, so we would rather measure your boat than guess at it.
Why the material line is separate
Owners sometimes read a separate material line as a way to hide cost. It is the opposite. Antifouling paint varies enormously in price, from budget single season coatings to multi season copper formulations that cost several hundred dollars a gallon. How much your boat needs depends on length, beam, wetted surface, and how much the old coating soaks up. Quoting labor and material as one blended number would mean guessing high on paint and keeping the difference, or guessing low and coming back to you later. We would rather show you both lines.
Also worth asking any yard: whether you may supply your own paint, and what they mark up on product they supply. Yards commonly sell paint above wholesale, and some will not let outside product through the gate at all, which is a reasonable policy given disposal rules but an expensive surprise if you bought five gallons in advance.
What has to happen first
The boat has to come out. Our haul out is $300 and includes the lift, power wash, blocking, and your spring launch. Bottom work is done while the boat is on the hard, so most owners pair the two and get the whole thing handled in one visit.
Why We Wash the Same Day We Haul
Bottom paint prep starts before anybody picks up a roller. When a hull comes out of Mill Creek covered in slime and barnacles, that growth is soft and it comes off under pressure in minutes. Leave it two days in the sun and it hardens onto the gelcoat. Now you are paying for scraping and sanding that a same day wash would have avoided entirely.
We wash on haul day. It is not a courtesy, it is the cheapest hour of the whole job.
Timing Your Bottom Job
Fall versus spring
Boat bottom painting works in either season. Painting in the fall means the boat is ready to launch the moment you want it in spring, with no waiting behind everyone else's April queue. Painting in spring means fresher paint at splash. What matters more is that the hull is clean and dry when the coating goes on.
How often
Depends on the paint, the water, and how much you run the boat. Ablative on a boat that sees regular use out of our creek often goes two or three seasons. A boat that sits still fouls faster than one that moves, which is worth knowing if your slip time and your actual water time are not the same number.
The boat that sits
Fouling is a function of stillness more than time. A hull that runs regularly through Mill Creek and out to Noyac Bay sheds growth as it moves, especially with ablative paint. A boat that stays in the slip all August while you are busy collects growth faster than a boat that goes out every weekend, even though both spent the same number of days in the water. If your actual water time is lower than you planned, expect your bottom to need attention sooner than the paint's rated life suggests.
Ask this at every yard
Ask whether they let you supply your own paint, and what they charge per gallon if you cannot. Ask whether do it yourself bottom work is permitted. Many yards forbid it outright, because sanding dust and antifouling residue carry real disposal rules, and owners routinely show up with a roller and a plan only to be turned around at the gate. Get the answer before you book anywhere.
