Quick Answer
Yes, tarred bankline can be used for building makeshift rafts, but it's essential to consider its limitations and potential risks. Tarred bankline is less flexible than other cordage options, but it can still be effective in a survival situation. Proper preparation and application are crucial for success.
Choosing the Right Bankline
When selecting tarred bankline for building a makeshift raft, look for a section with a diameter of at least 1-2 inches (2.5-5 cm). This size will provide enough buoyancy and strength for a small raft. Avoid banklines that are frayed, damaged, or have loose tar, as they can compromise the integrity of the raft.
Preparing the Bankline
To prepare the bankline, remove any excess tar by wiping it with a cloth or letting it sit in the sun for a few hours. This will make the bankline easier to work with and reduce the risk of it becoming too sticky. Use a sharp knife or pruning saw to cut the bankline into manageable lengths, typically 6-8 feet (1.8-2.4 meters) long.
Building the Raft
To build the raft, lay out 2-3 bankline lengths parallel to each other on a flat surface, spaced about 1 inch (2.5 cm) apart. Weave additional bankline lengths across the first layer in a crisscross pattern to create a sturdy base. Continue adding layers, overlapping the previous ones by about 6 inches (15 cm), until the raft reaches the desired size. Use rocks, sticks, or other materials to secure the bankline to the raft frame.
