Disclaimer
* Pricing includes tax and is based on boat length (linear feet). Rates apply to the hull only — rub rail down to the waterline. Topside, swim platforms/sterns, and interior services are additional. Final pricing is confirmed after an in-person inspection, as photos may not accurately show current condition. Oxidation level, staining, access, and any required sanding may affect the final quote.
Not Sure Which Package You Need?
Send us a few photos of your boat, and we’ll tell you exactly what level of correction or maintenance it requires — no guesswork.
How Our Process Works
This is the process used on every restoration, correction, and maintenance service we provide — designed to deliver consistent, premium results for every boat we work on.
1. Assessment & Condition Check
You send us photos of your boat, and we evaluate:
• oxidation level
• fading and UV damage
• waterline stains
• patchiness or porosity
• previous repairs or coatings
This allows us to recommend the right package — without guesswork.
2. Detailed Preparation
We prepare your boat properly before any correction work begins:
• full decontamination wash
• mineral and water spot removal
• tape and mask sensitive areas
• rinse and inspect the surface
Prep is everything — it ensures our correction stages work as intended.
3. Correction Stage (Cutting + Polishing)
Depending on your boat’s condition, we perform:
• wet sanding (600–800–1000 grit if required)
• machine compounding
• machine polishing
• swirl/haze removal
• colour and gloss recovery
This is where the transformation happens.
4. Protection & Finishing
Once the gelcoat is corrected, we lock in the results with:
• marine-grade polymer protection
• ceramic coating (optional upgrade)
• high-gloss finishing polish
This step ensures your boat looks great longer — and is easier to maintain.
5. Final Inspection & Photo Walkthrough
We review the finish in natural light and:
• check reflectivity and clarity
• inspect waterline and bow
• confirm gloss and evenness
• send you before/after photos
• walk you through what was done
You see exactly what we achieved and how to keep it looking its best.
