— The Build Process

From raw iron
to open water.

The full backyard build system — every tool, every cut, every safety check.

— Materials Used

Built honestly.
Built strong.

  • Sheet Iron (2–3mm): The hull's structural skin, treated for rust resistance.
  • Hardwood Rods: Cedar, oak or pine for ribs and decking.
  • Marine Sealant: High-flex polyurethane for watertight joints.
  • Stainless Fasteners: Bolts, rivets and bracketry.
  • Marine Paint: Two-component gloss black topcoat.

— Tools Required

Your backyard arsenal.

Welding Setup

MIG or stick welder, appropriate gauge wire and shielding gas.

Angle Grinder

For cutting and finishing iron sheet edges cleanly.

Hand Tools

Clamps, hammers, drills, measuring tapes and squares.

Wood Saw

Circular or jigsaw for shaping deck rods and ribs.

Sander

Random orbital for paint prep and wood finishing.

Spray Gun

For an even gloss black marine-grade finish.

— Step By Step

The build, in detail.

01

Design & Blueprint

Define hull length, beam, depth and seating. Print or sketch full-scale templates of every rib.

02

Cut The Iron

Trace ribs and panels onto sheet iron. Cut with grinder, deburr edges, label each piece.

03

Frame Assembly

Tack-weld ribs to a central keel. Verify symmetry with cross-measurements before final welds.

04

Skin The Hull

Wrap and weld iron panels to the frame. Grind welds smooth. Pressure-test for leaks.

05

Wood Decking

Fit hardwood rods across the deck. Bolt down with stainless fasteners and seal joints.

06

Finish & Float

Sand, prime, gloss-coat. Cure 72 hours. Tow to water. Float test in shallow water first.

— Safety First

Respect the build.
Respect the sea.

  • Always wear a welding mask, gloves and flame-resistant clothing.
  • Work in a ventilated area when grinding, welding or painting.
  • Never test a new boat alone — always with a spotter and life vest.
  • Inspect welds and seals before every season.
  • Comply with local maritime registration laws before launch.
