Boat Side Rails: What Are They Called?

When you're out on the water, you might hear the terms "gunwale" or "rail" being thrown around. But what exactly are these parts of a boat called, and what do they do? Let's dive in and explore the fascinating world of boat terminology.

Boats, much like cars, have their own unique language. Understanding this language can help you navigate the waters more safely and confidently. So, let's start by discussing the side rails of a boat, which are often referred to as the "gunwale" or "rail".

Gunwale: The Top Edge of the Boat

The gunwale is the top edge of the boat's side, where the hull meets the deck. It's often reinforced to provide additional strength and stability. This term originates from the Old Norse word 'gund', meaning 'rear', and 'wael', meaning 'wall'.

Gunwales serve several crucial purposes. They help to prevent water from splashing into the boat, provide a sturdy handhold for passengers, and can also be used to step over when boarding or disembarking. In some boats, the gunwale may also double as a seat or a place to rest your feet.

Types of Gunwales

Gunwales can be found in various shapes and sizes, depending on the type of boat. For instance, a canoe's gunwale is typically narrow and rounded, while a rowboat's gunwale is often wide and flat. Some boats may have a gunwale that's reinforced with a lip or a cap, providing extra strength and stability.

In some boats, the gunwale may also serve as a mounting point for other features, such as cleats for tying off lines or brackets for mounting equipment like fishing rods or navigation lights.

Gunwale Construction Materials

The material used to construct the gunwale can vary greatly depending on the type of boat. Traditional wooden boats often have gunwales made from the same material as the hull, while modern boats may use materials like aluminum, fiberglass, or even plastic.

In some cases, the gunwale may be made from a different material than the rest of the boat. For example, a wooden boat might have an aluminum gunwale to provide additional strength and durability. This is often referred to as a "gunwhale band" or "gunwhale cap".

Rail: The Handrail of the Boat

When people refer to the "rail" of a boat, they're typically talking about the handrail that runs along the side of the boat. This rail provides a sturdy handhold for passengers, helping to prevent falls and providing stability when the boat is in motion.

Boat rails can be found in a variety of shapes and sizes, from the simple, round handrails on small pleasure boats to the complex, multi-level rail systems found on large cruise ships.

Types of Rails

One common type of rail is the "bulwark", which is a low, wide rail that runs along the side of the boat. Bulwarks provide a sturdy handhold and also help to prevent people from accidentally falling overboard.

Another type of rail is the "lifeline", which is a high, often wire-like rail that runs around the perimeter of the boat. Lifelines provide a safety barrier, preventing people from falling overboard, and can also be used to secure safety harnesses.

Rail Construction Materials

Like gunwales, boat rails can be made from a variety of materials. Traditional wooden boats often have wooden rails, while modern boats may use materials like aluminum, stainless steel, or even plastic.

In some cases, the rail may be integrated into the boat's structure, providing additional strength and stability. For example, on a sailboat, the rail may be part of the boat's "bulkhead", which is the structural wall that separates the boat's interior into different compartments.

Understanding the terminology of boat parts can help you better maintain and navigate your vessel. Whether you're a seasoned sailor or a first-time boater, knowing the difference between a gunwale and a rail can make your time on the water more enjoyable and safer. So, the next time you're out on the water, take a moment to appreciate the craftsmanship and design of your boat's side rails.
