Directional stability
From KayakWiki
Directional Stability is the tendency of a hull to maintain a straight path when in motion. One that tends to turn is not directionally stable. Sometimes referred to as longitudinal stability.
The following factors tend to increase directional stability:
- A long keel line
- A deep Vee keel
- Fine ends
- Skegs or rudders
Increasing the rocker tends to reduce longitudinal stability.
