Why Choose Ipe for Dock Decking
Ipe dock decking is the gold standard for marine construction. NYC's Coney Island boardwalk, the Atlantic City boardwalk, and countless commercial marinas from Maine to Florida rely on Ipe because no other wood survives saltwater environments like Brazilian walnut. At 3,684 Janka hardness with 69 lbs/ft³ density, an Ipe wood dock delivers 75+ years of service in the harshest marine conditions — constant water contact, splash zones, submersion cycles, salt spray, UV bombardment, and freeze-thaw.
What makes Ipe the best wood for boat docks is its natural resistance to Teredo worms and Limnoria — the marine borers that destroy pressure-treated lumber in saltwater within 5-10 years. Ipe's natural oils and extreme density create a barrier these organisms cannot penetrate. No chemical treatment is needed, which means zero CCA, ACQ, or copper leaching into your waterway. This matters critically for environmental permits, fish habitats, and marine wildlife — an Ipe dock is the environmentally responsible choice for any waterfront.
Ipe dock boards provide a splinter-free, barefoot-safe surface with excellent wet slip resistance. Dense hardwood maintains good traction even when constantly wet — unlike pressure-treated pine that becomes dangerously slippery with age and algae growth. The surface stays cooler than composite and PVC alternatives that become painfully hot in direct sun. For a dock where people walk barefoot in swim gear, this daily comfort matters.
The structural strength of Ipe dock lumber handles everything a marine environment demands: heavy boat traffic, equipment loads, crowd loading on commercial piers, and decades of wave action. The 75+ year lifespan means an Ipe dock is typically the last dock you'll ever build — while pressure-treated docks need replacement every 10-15 years in marine settings.

Dock Installation Tips for Ipe
Use 316 stainless steel fasteners — mandatory for marine/saltwater (not 304). Joist spacing: 16" OC standard, 12" OC for heavy commercial or 2x boards. Leave 3/16" gaps between boards for drainage and debris clearance. Pre-drill all holes with carbide bits. Seal all cut ends — critical in marine environments where moisture intrusion is constant. Acclimate 7-14 days on-site before installation. Ipe dock boards work on wood pile, steel pile, aluminum frame, and concrete substructures. No chemical treatment needed — a key advantage for waterway compliance.

| Cost (50-year) | Lowest | Highest (replace 3-4x) | Higher | Higher | Moderate |
Ipe Dock vs Pressure-Treated Dock
PT lumber lasts 10-15 years on docks — Ipe lasts 75+. PT splinters badly, becomes slippery, and leaches CCA/ACQ chemicals into your waterway. Ipe is splinter-free, slip-resistant, and chemical-free. Over 50 years, an Ipe dock costs less because PT requires 3-4 complete replacements.
Ipe Dock vs Composite Dock
Composite dock boards get extremely hot in sun, sag under load, lack structural strength, and shed microplastics into waterways. Ipe stays moderate temperature, carries any load, and is 100% natural. Composite docks last 15-20 years; Ipe lasts 75+.
Ipe Dock vs Cumaru Dock
Cumaru delivers 90% of Ipe's marine performance at 30-40% lower cost. For large dock projects, the savings are substantial. Choose Ipe for maximum lifespan and proven saltwater track record; Cumaru for best value.
