AY Honors/Rock Climbing - Advanced/Requirements

13. Do one of the following:

a. Assist in constructing a raft, using lashings. Take a five-mile (8.3 km) trip on a river with this raft.

The greatest problem you will need to overcome when building a raft from logs is that logs are very close to having neutral buoyancy, meaning that they do float, but only barely. To deal with this, you will need a great many number of logs.
