Securing Boat Rails: Aluminum Fastening Techniques

Boat rails are an essential safety feature for any vessel, providing stability and ease of movement, especially in rough conditions. They are also important for protecting the hull from bumps and scratches when docking. While boat rails come in various materials, such as stainless steel and vinyl, aluminum is a popular choice due to its durability, resistance to corrosion, and ease of maintenance. When installing boat rails, it's crucial to consider factors such as height, material, colour, and finish to ensure a secure fit and aesthetic appeal. In this discussion, we will explore the process of securely attaching boat rails to aluminum, addressing the specific considerations and techniques involved.

Using rivnuts to secure rails

Rivnuts are a popular choice for securing boat rails to aluminium. They are an alternative to using sheet metal screws directly into the aluminium and provide an anchor point for mounting. They are also useful when you don't have access to the underside of the boat to use a nut and bolt.

Rivnuts are best suited for areas where you can't get to the other side to secure a nut and bolt. They are also a good option if you want to be able to remove whatever you are mounting.

When using rivnuts, it is important to consider the thickness of the aluminium. They can be used with thin aluminium but thicker aluminium will result in a stronger hold. It is also important to note that if the mounted object flexes or rocks back and forth, it can cause the aluminium to crack where the rivnuts are installed and may pull them out over time.

To install rivnuts, you will need to drill a hole in the aluminium. The size of the hole will depend on the size of the rivnut and bolt being used. It is recommended to use a drill bit that is the same size as the rivnut mandrel.

When choosing rivnuts, consider the material and grip range. Stainless steel or aluminium rivnuts are suitable for marine use. The grip range should match the thickness of the aluminium to ensure a secure fit.

After installing the rivnuts, you can attach the boat rails using bolts. It is important to select the correct size of bolts that match the size of the rivnuts.

Some boat owners have reported success using rivnuts to secure their boat rails, while others have experienced them working loose over time. It is important to consider the specific application and follow the manufacturer's recommendations.

Aluminium boat hand rails

When choosing aluminium boat hand rails, it's important to consider factors such as height, material, and colour. The hand rails should be tall enough to provide adequate support and cover the full height of the deck-to-hull seam. Aluminium is a popular choice for hand rail material due to its durability, resistance to corrosion, and ease of maintenance.

To secure aluminium boat hand rails to your boat, one method is to use aluminium rivnuts. Rivnuts provide a strong and secure connection between the hand rail and the boat's gunwales or hull. Another method is to weld the hand rails in place, although this requires more specialised equipment and skills. Additionally, aluminium channel "blocks" can be attached to the inside of the top rail, providing a mounting point for the hand rails.

When installing aluminium boat hand rails, it's important to ensure that the rails are compatible with your boat's design and that you follow the correct safety procedures. Hand rails should be installed securely and tested to ensure they provide stable support in various conditions.

By choosing the right aluminium boat hand rails and installing them correctly, you can enhance the safety, functionality, and aesthetics of your boat. These hand rails provide essential support and stability, especially during challenging weather conditions, making them a valuable addition to any vessel.

Choosing the right height for aluminium rails

Firstly, you need to measure the height of the deck-to-hull seam that the rails will be covering. The aluminium rails should be tall enough to cover the entire height of this seam. If the rails are too short, the seam will be left exposed, defeating the purpose of the rub rails. On the other hand, rails that are too long will result in an unsightly overhang.

It is recommended to measure the height of your current rub rails and choose a replacement that is similar in height. If your boat does not have pre-existing rub rails, you can calculate the required length using the formula: (Boat Length) x Beam Measurement + Extra. The "extra" length will depend on how far you want the rails to extend across the transom, and it is generally advisable to order at least 10 extra feet for installation adjustments.

Additionally, consider any specific height requirements based on your boat's usage. For example, certain regulations dictate that rails on passenger decks of ferries or vessels engaged in excursion trips must be at least 39.5 inches high. On the other hand, if your boat is used for big game angling, you may need to reduce the minimum rail height to accommodate specialised equipment, such as a pedestal-mounted fighting chair.

By carefully considering these factors, you can choose the right height for your aluminium rails, ensuring both functionality and compliance with any relevant safety standards.

Aluminium rail maintenance

Aluminium boat rails are a critical safety feature and require regular maintenance to keep them in top condition. Here are some tips for maintaining aluminium boat rails:

Preventing Corrosion

Aluminium is highly resistant to corrosion, but it's important to take preventive measures to protect the anodized coating. Avoid using abrasive items, cleaners, or impacting the aluminium with hard objects like knives or gaffs, as these can damage the coating. Wash your boat regularly with fresh water and a mild, non-abrasive soap, especially if it's stored near water or exposed to harsh chemicals. Pay close attention to the pipe and tubing underneath the top or canvas, as these areas are often overlooked and can be prone to staining or pitting.

Choosing the Right Cleaning Products

Not all cleaning products are suitable for aluminium. Avoid using bleach, chlorides, abrasive cleaners, or steel wool on aluminium surfaces. Instead, opt for mild dishwashing liquid or specialty marine cleaners specifically designed for aluminium and stainless steel.

Keeping Your Boat and Aluminium Rails Dry

Proper drainage is crucial to prevent corrosion. Keep your outboard attached and angle your boat for proper drainage. Ensure that sand or other debris doesn't interfere with drainage, as this can trap moisture and cause corrosion.

Protecting Against Impact

Aluminium boat rails are designed to protect the hull from bumps and scratches. However, impact from docking or other objects can damage the aluminium. Consider using UHMW tape or a keel guard to protect the aluminium from impact, especially if you frequently dock in areas with protruding hardware.

Regular Maintenance and Inspection

Regularly inspect your aluminium boat rails for any signs of damage or corrosion. Maintaining your boat rails is about more than just cleaning; it's important to match the right products to their materials. By following these maintenance tips and choosing the appropriate cleaning products, you can ensure your aluminium boat rails remain in top condition for years to come.

Aluminium rail installation

Aluminium boat rails are a popular choice among boat owners due to their durability, resistance to corrosion, and aesthetic appeal. They serve both safety and cosmetic purposes, protecting the hull from bumps and scratches, and enhancing the overall appearance of the boat.

When installing aluminium rails, there are several factors to consider. Firstly, ensure that the height of the rail is appropriate for your boat. The rail should be tall enough to cover the full height of the deck-to-hull seam, preventing any exposure. Secondly, take into account the material of the rail. Aluminium is a preferred choice due to its strength and resistance to corrosion, especially in marine environments.

There are a few methods for securing aluminium boat rails. One common approach is to use rivets. Rivets provide a strong and secure connection between the rail and the boat's hull.
