The Sail-to-Displacement (SA/D) Ratio is a key performance indicator for a sailboat. It compares the sail's power (sail area) to the boat's weight (displacement), providing a quick way to gauge a boat's potential speed and handling characteristics. A higher number generally indicates a more performance-oriented boat, while a lower number suggests a more docile, heavy-weather-oriented vessel.
Key Concepts:
Sail Area (SA): The engine of the boat, measured in square feet.
Displacement (D): The weight of the boat, measured in pounds.
< 14: Heavy offshore cruisers, very stable.
14-20: Typical range for coastal cruisers, a good balance.
> 20: Performance cruisers and racing boats, fast but demanding.
