Quick Answer
To create a makeshift sail from a life raft, use the inflatable tubes to create a triangular shape by attaching the ends to the raft's deck and securing the base with ropes. This basic design can be improved by adding a mast made from a long, sturdy object and a makeshift boom for better control.
Gathering Materials
Find suitable objects to use as a mast, such as a long wooden oar or a fiberglass rod. Look for a sturdy material to use as a boom, such as a long, thin piece of plastic or a metal rod. Additionally, gather rope or cordage to secure the sail and the mast.
Creating the Sail
Use the inflatable tubes to create the triangular shape of the sail. Attach the ends of the tubes to the life raft’s deck using ropes or cordage, making sure they are tightly secured. Measure the length of the tubes and calculate the angle at which they should be attached to maximize wind catch. A typical angle is between 30 and 40 degrees. Use additional ropes or cordage to secure the base of the triangle, making sure it is stable.
Rigging the Mast and Boom
Find a suitable anchor point on the life raft to attach the mast. Use rope or cordage to secure the mast, making sure it is tightly tied. Create a makeshift boom by attaching the end of the boom material to the mast using rope or cordage. Measure the length of the boom and adjust its angle to optimize sail performance. A general rule of thumb is to angle the boom between 10 and 20 degrees relative to the mast. Adjust the sail’s angle and the boom’s position to maximize wind catch and minimize drag.
