Aquaphobix™ costs $300 per linear foot of boat length, applied once by a licensed dealer and backed by a 5-year transferable warranty. A 25-foot boat comes to about $7,500 and a 35-foot boat about $10,500. That is more than a single bottom paint job, which typically runs $1,500 to $3,200 on a 35-footer, but bottom paint is redone every one to two seasons in salt water. The real comparison is five years of repainting against one application.
Aquaphobix™ is priced at $300 per linear foot of boat length, applied by a licensed dealer. That works out to about $7,500 on a 25-foot boat, $9,000 on a 30-foot boat, and $10,500 on a 35-foot boat. Your dealer confirms the exact quote after seeing the boat.
You are paying for five years at once. A bottom paint job buys one to two seasons in salt water before the boat comes out again for sanding and repainting. Aquaphobix™ is a non-ablative thermopolymer hull coating that is heat-embedded into the hull one time, so the cost that bottom paint spreads across repeated haul-outs is paid in a single application backed by a 5-year transferable warranty.
It depends on how often your boat is repainted and what your yard charges. A 35-foot boat repainted every year at typical full-service prices spends about $7,500 to $16,000 on bottom paint over five years, and Aquaphobix™ at $10,500 falls inside that range. A boat repainted every other year at the low end of yard pricing spends less on paper, and it is worth knowing that before you decide.
Boat length sets the price, since Aquaphobix™ is quoted per linear foot. Beyond length, your dealer checks the hull material, the condition of the surface, and what is on the bottom now, because any existing bottom paint is removed before the coating goes on.
Yes. Aquaphobix™ carries a 5-year transferable warranty, so if you sell the boat inside that window the next owner inherits the remaining coverage. Your dealer can walk you through the full warranty terms before the application.
Multiply your boat's length in feet by $300. A 28-foot boat, for example, comes to about $8,400. For the exact quote, a free 15-minute consultation confirms the number and which dealer covers your area.
Bottom paint is priced like a consumable because it is one. Ablative paint is engineered to wear away as the boat moves through the water, which is how it keeps exposing fresh biocide, and it is also why the job has to be repeated. Every cycle means a haul-out, blocking, sanding, fresh coats, and days the boat is not on the water.
Aquaphobix™ is priced like equipment. It is a non-ablative thermopolymer hull coating that a licensed dealer heat-embeds into the hull. It contains biocides, but because it does not ablate, they stay locked inside the coating instead of leaching into the water the way ablative paint does. One application, one invoice, and a 5-year transferable warranty behind it.
Published 2026 price guides give a consistent picture. West Marine's guide puts a straightforward professional recoat at $20 to $40 per foot of boat length, with haul-out at another $8 to $20 per foot. Boatyards.com puts a complete professional bottom job on a 35-foot boat at $1,500 to $3,200 depending on prep, and $3,500 to $5,000 when the hull has to be stripped back to gel coat. On how often, West Marine expects bottom paint to last about one season in moderate fouling, Boatyards.com lists every one to two years in salt water, and a 2026 Tampa Bay guide budgets for repainting every 12 to 24 months on wet-slipped boats.
Run those numbers across five years on a 35-foot boat, counting the first job:
Those bottom paint totals leave out the strip-to-gel-coat job that layers of old paint eventually call for, which adds $3,500 to $5,000 in the year it comes due.
If your boat is repainted every other season at low yard rates, bottom paint costs less over five years on paper, and it is better to say that plainly than to pretend otherwise. If your boat lives on a trailer or a lift, you may not need any bottom coating at all, so start there.
The five-year numbers move toward Aquaphobix™ for boats that sit in warm salt water, come out every year, and pay full yard rates. That describes a lot of slip-kept boats in Florida and along the Gulf Coast, and it is where the one-application model makes the most sense.
The invoice is only part of the cost of bottom paint. Each repaint takes the boat out of service while the yard hauls, preps, paints, and splashes it.
With Aquaphobix™, there is no repaint cycle inside the five-year warranty window. Growth that tries to settle cannot bond firmly to the surface, so it wipes or power-washes off, even in the water. The 5-year warranty is transferable too, which gives a buyer something documented to look at when the boat is surveyed.
