Mounting Downriggers: Aluminum Bass Boat Essentials

Mounting downriggers on an aluminium bass boat can be a challenging task, especially when it comes to ensuring the setup is secure and safe. One popular method is to mount the downriggers on a plank that runs across the gunwales, using mounting plates and screws. However, this approach may require tearing apart the boat's interior to access the underside of the shelf for proper installation. Another option is to build a support structure that ties into the vertical aluminium seat supports or the boat's angle stock. Isolating the downriggers from the boat with rubber can also help to increase the catch rate by reducing noise and vibration. When mounting downriggers, it is crucial to consider the weight of the balls and the length of the booms to avoid putting excessive stress on the mounting points.

Reinforcing with braces to prevent lifting

Reinforcing with braces is a great way to prevent lifting when mounting downriggers on your aluminium bass boat. Here are some detailed steps and tips to help you get started:

Planning and Materials

Before you begin, it's important to plan the location of your downrigger mount carefully. Consider the weight of the downrigger and the ball weights you intend to use. Mark the location of the mount on the seat and drill holes for the bolts. You will need backing plates, aluminium strips, washers, nuts, and locktight for assembly.

Assembly

To reinforce your downrigger mount and prevent lifting, follow these steps:

• Attach backing plates to the underside of the mount location. These provide additional support and help distribute the load.
• Secure the downrigger mount to the seat using bolts, washers, and nuts. Pass the bolts through the drilled holes and tighten them securely.
• Consider adding aluminium strips on the top side of the mount for added security. These strips can be plasti-dipped or coated with clear silicone to prevent sharp edges from snagging lines or damaging the vinyl bench cover.
• Fabricate braces to connect the downrigger tower to the gunnel. These braces will prevent the base of the downrigger from pulling up under the weight of the ball.
• Test the setup by extending the boom and attaching the heaviest ball weight you intend to use. Ensure that the added weight does not pull up on the seat or the mount. Adjust the braces as needed to maintain a stable position.

Additional Tips:

• Isolate your downriggers from the boat using rubber to reduce noise and increase your catch rate.
• Consider using swivel bases for your downriggers, as they provide more flexibility and ease of use.
• If you're concerned about the weight or leverage of larger downriggers, opt for shorter booms.
• Regularly inspect your setup and make adjustments as needed to ensure stability and safety.

Isolating downriggers from the boat using rubber

When mounting downriggers on an aluminium bass boat, it is important to consider the impact of noise and vibrations on your catch rate. Aluminium boats are particularly noisy, and isolating your downriggers from the boat using rubber will increase the number of fish you catch.

To isolate your downriggers from the boat, you can use rubber washers or grommets at the mounting points. This will help to absorb the vibrations and reduce the amount of noise that is transferred from the boat to the downrigger. You can also use rubber pads or strips between the downrigger and the mounting surface to create a barrier and further reduce the transmission of vibrations.

In addition to rubber, you can also use other soft materials such as foam or plastic to isolate the downrigger. These materials can be cut to size and placed between the downrigger and the boat to create a cushion and reduce the amount of direct contact between the two. This will help to dampen the vibrations and reduce the noise that is transferred to the water.

It is also important to consider the placement of your downrigger when trying to minimise noise and vibrations. As aluminium boats are noisy, placing the downrigger as far away from the engine as possible will help to reduce the amount of noise and vibration that is transmitted through the boat to the downrigger.

Drilling holes in aluminium backing

Drilling into aluminium should be a straightforward process if you follow some basic guidelines. Firstly, it is important to prioritise safety. Always wear eye protection as drilling into metal produces tiny, sharp fragments that can cause serious eye injury. Work gloves are also recommended for protection from metal shards.

Next, select an appropriate drill bit. Aluminium is a soft metal, so a standard HSS drill bit will suffice. However, due to aluminium's low melting point, a cobalt drill bit is preferable as it dissipates heat more effectively, reducing heat buildup.

Before drilling, it is essential to secure the aluminium with clamps to prevent it from spinning or causing injury. Mark the desired location for the hole with a centre punch and hammer to create a small dimple, which will help guide the drill bit.

When drilling, choose the correct speed, typically between 200 and 300 rpm for aluminium. Avoid applying excessive pressure and maintain lubrication to minimise heat buildup and friction. Drill at a slow speed to prevent the bit from overheating.

If you need to create a large hole, start with a small hole and gradually increase the size with successive drilling. To remove any sharp edges or burrs left behind, use a deburring tool or a slightly larger twist bit to smooth out the edge of the hole.

Additionally, consider using a drill press for greater accuracy and better results. These machines are designed with metalworking in mind and allow for precise, straight holes.

Using coarse-threaded screws

To mount downriggers on an aluminium bass boat using coarse-threaded screws, you can follow these steps:

First, you need to decide where you want to position your downriggers. Some options include mounting them on a plank of wood that runs across the gunwales, building a support structure that ties into the vertical aluminium seat supports, or attaching a mounting plate to the angle stock used to stiffen the sides of the boat. Once you have decided on a location, you can begin the mounting process.

If you are mounting through the gunwales, you will need to measure and mark the desired location. Remove the bench seat and drill holes in an aluminium backing plate that will be placed on the bottom of the gunwale. Secure the backing plate with coarse-threaded screws, washers, and nuts. You can also add strips of aluminium or a brace to the top side of the gunwale for additional support.

If you are unable to access the underside of the gunwale to secure the mounting plate, you can use coarse-threaded screws with a wood backer underneath to secure the plate. Make sure to use the appropriate screw length and drill pilot holes to avoid damaging the aluminium.

When mounting downriggers, it is important to consider the weight of the downrigger ball and the length of the boom. Heavier balls and longer booms may require additional reinforcement to prevent lifting or pulling on the mounting surface. You can also use a brace or swivel to distribute the weight more evenly and reduce stress on the mounting point.

Always make sure to test your downrigger setup before use and adjust your clutches to handle the heaviest weight you plan to use. This will help prevent damage to your boat or equipment in case of snagging or other issues.
