Fin Keel
Also known as: fin, vertical keel
A type of keel that extends vertically downward from the hull with a relatively thin profile. Fin keels offer excellent upwind performance, reduced wetted surface, and better maneuverability compared to full keels or long keels. Most modern production yachts use fin keels, often with a bulb at the tip to lower the center of gravity.

Draft
The vertical distance from the waterline to the lowest point of the keel, also known as the yacht's keel depth. Shoal draft yachts (under 1.5m) can access shallow coastal waters and anchorages but may sacrifice upwind performance and stability compared to deeper draft designs.
Dimensions
Wing Keel
A fin keel with horizontal wings or plates at the bottom, designed to reduce draft while maintaining ballast weight and stability. Wing keels are popular in cruising yachts for shallow-water access, though they may have slightly reduced upwind performance compared to a deeper fin keel of similar stability.

Shoal Draft
A shallow keel depth, typically under 1.5 meters (5 feet). Shoal draft yachts can access shallow anchorages, coastal waters, and inland waterways that deeper vessels cannot. This design trades some upwind performance and initial stability for the versatility of exploring shallow waters.
