Tewantin Plans
Speed Meets Simplicity
Unleash your inner boatbuilder with Tewantin, the fast and versatile sports boat that's as thrilling to build as it is to drive. Slightly shorter than the Noosa but with a 33% wider beam and taller sides, this boat offers more space, stability, and performance.
Ideal for motors between 6–10hp (max 15hp), the Tewantin is lightweight enough to carry on your car roof. CNC files are also available for precision cutting.
Why You'll Fall in Love with Tewantin
Driving the Tewantin feels like gliding on water. With her lightweight design, smooth bottom, and refined hull shape, this boat leaps onto the plane effortlessly and stays there with minimal power. It's a ride that offers unparalleled control and responsiveness.
The hull design, perfected through extensive trials and improvements, outshines traditional V-bottoms with better stability and superior planing performance. With computer-generated plans, every piece fits together seemlessly, making the building process as smooth as the ride.
Light and portable, the Tewantin can be carried on your car roof or loaded onto a small trailer. I used to carry her solo atop my old Ford XC Falcon! A 6hp Mercury 2-stroke engine, weighing just 26kg, powered my adventures—and it fit neatly into my car's trunk. While she's too wide to carry along narrow paths like the Noosa, once she's on the water, Tewantin leaves any tinnie in her wake.

Materials Needed
Crafting your Tewantin is straightforward and cost-effective, with flexibility in material choices to suit your budget and style. Here's an overview:
Plywood
You don't need marine-grade plywood; economy-grade exterior plywood works perfectly. If you prefer, marine ply adds the highest quality and a polished look when left unpainted or varnished, but it's not essential.
Sheets Required:
- 4 sheets of 6mm (1/4") plywood (5 sheets for CNC cutting)
- 1 sheet of 9mm (3/8") plywood
Framing
Use economical pine for handrails, seat edges, and framing, or opt for cedar for lightweight durability or hardwood for a premium finish.
Framing Required:
- Approximately 15–20m (50–65 ft) of wood framing
Other Materials
- Epoxy Resin: ~10 liters
- Epoxy Filler: Small amounts of different types
- Fiberglass Tape: ~60m (200 ft) of 50mm (2") tape
- Paint: Minimal quantities—several options available
- Foam Buoyancy: For additional safety
- Motor: 6–10hp recommended, max 15hp
- Assorted Fittings: For finishing touches
