The gunwale (also spelled "gunnel") is the reinforced upper edge of a boat or yacht's hull, where the deck meets the side. It serves key functions: enhancing vessel stability (especially in rough waters), acting as a mounting point for accessories (fishing rod holders, cleats), protecting the interior from water damage, and providing a secure seating/grip area for passengers. Different boat types (yachts, canoes, narrowboats) feature varied gunwale designs, but it remains a critical structural component of any vessel.
