Can You Build a Floating Platform With Just Logs?

Choosing the Right Logs

When selecting logs for your floating platform, look for straight, knot-free, and evenly-sized logs. Ideally, choose logs with a diameter of 10-20 inches (25-50 cm) and a length of 12-16 feet (3.6-4.9 meters). This size will provide sufficient buoyancy and structural integrity to support a person or small load.

Lashing Techniques

To lash the logs together, use natural fibers like cordage, rope, or vines to create a sturdy and water-resistant bond. Start by creating a square or rectangular shape with four logs, then add additional logs to create a framework. Use a “X” pattern lashing technique to secure each log in place, overlapping the lashings by 6-8 inches (15-20 cm) to ensure maximum stability. Use 3-4 lashings per log, spaced evenly apart, to distribute the weight and prevent logs from shifting or rotating.

Floating Platform Design

Design your floating platform to be at least 8 feet (2.4 meters) wide and 12 feet (3.6 meters) long to provide a stable surface for walking or standing. Consider adding a slight incline to the platform to prevent water from accumulating and ensure better drainage. Use a combination of logs and lashings to create a sturdy frame, then add additional logs on top to create a flat surface. To add extra buoyancy, you can also attach smaller logs or branches to the underside of the platform.
