Boat Hull Structural Diagram: Rib, Base, and 2x2 Runners Explained #1975260 (License: Personal Use)

This schematic highlights the critical load-bearing elements of a small boat’s hull: the vertical rib provides lateral stiffness, the angled base supports the hull’s bottom edge, and the red-outlined 2x2 runners serve as longitudinal reinforcements at the keel. The curvature of the hull side (blue line) shows typical fairing for hydrodynamic efficiency, while the black base line represents the waterline or chine.

Used on marine engineering, DIY boatbuilding, or naval architecture pages to explain hull reinforcement techniques; matches user intent for understanding structural design, repair, or fabrication guidance.
