14–17 ft	$400–$800	$600–$1,200	$1,000–$2,000	$150–$350
18–22 ft	$700–$1,200	$900–$1,800	$1,600–$3,000	$250–$500
23–28 ft	$1,000–$1,800	$1,500–$2,800	$2,500–$4,500	$400–$800
29–35 ft	$1,600–$2,800	$2,200–$4,000	$3,800–$6,500	$600–$1,200
36–45 ft	$2,500–$4,500	$3,500–$6,000	$6,000–$10,000	$900–$1,800
46 ft+	$4,000+	$5,500+	$9,500+	$1,500+

Professional rates include haul-out, pressure washing, sanding, primer, paint, and relaunch. DIY figures cover materials only and assume the boat is already out of the water. Add $200–$600 for haul-out and blocking at most yards if not included.

What DIY Materials Actually Cost

A realistic DIY materials budget for a 20-foot fibreglass boat covers five categories.

Item	Cost Range	Notes
Surface preparation	$80–$150	Sandpaper, sanding pads, cleaning solvent. Do not skip — paint adhesion on a poorly prepared surface fails within one season.
Primer	$40–$90 per gallon	Epoxy primer for below-waterline work. A 20ft boat requires 1–2 gallons.
Bottom paint (ablative antifouling)	$80–$200 per gallon	A 20ft boat needs 2–3 gallons for two coats. Copper-free for freshwater; high-copper for offshore.
Topside paint (two-part polyurethane)	$60–$180 per litre	Single-part costs less but has shorter service life. Two coats standard at ~1 litre per coat.
Application tools	$60–$120	Brushes, rollers, trays, masking tape, respirator. A half-face respirator is not optional — isocyanate hardener is a sensitiser.
TOTAL (20ft boat)	$350–$700	Depending on paint quality choices.
