Unpowered vessels are sailboats or vessels that are paddled, poled, or rowed.
If less than 23.0 feet long, these vessels should:
- If practical, exhibit the same lights as required for unpowered vessels less than 65.6 feet in length.
- If not practical, have on hand at least one lantern or flashlight shining a white light as in illustration 3.
