Boat Trailers: Choosing The Best For Your Vessel

When it comes to choosing the best boat trailer, it's important to consider factors such as durability, ease of use, and corrosion resistance. With the rising prices of metals, it's worth noting that some manufacturers may compromise on quality, so it's essential to do your research before purchasing. The type of trailer you need will depend on the size and weight of your boat, as well as your budget.

For smaller boats, single-axle trailers are ideal, while larger vessels require the stability and weight distribution of dual or multiple axles. When it comes to materials, aluminium trailers are lightweight, corrosion-resistant, and suitable for saltwater environments, whereas galvanized steel trailers offer exceptional strength and are ideal for freshwater use.

Some of the top boat trailers on the market include the EZ Loader Adjustable Boat Trailers, which offer versatility and durability, and the Load Rite Aluminum Boat Trailers, which are known for their lightweight and durable design. The CE Smith Multi-Sport Boat Trailer is another great option for those with small boats, as it is simple and easy to use.

Boat trailer material

Boat trailers are typically made from either galvanized steel, painted steel, or aluminum. The material you opt for will depend on your budget, the weight of your boat, and the kind of water you usually navigate.

Steel Boat Trailers

Steel boat trailers are a good option for those who boat in freshwater. They offer greater stability than aluminum trailers and are more affordable. Painted steel models are a good entry-level option, offering durability at a lower price. However, steel is more susceptible to corrosion, so saltwater and road salt can affect the integrity of the trailer over time. To combat this, some steel trailers are galvanized, meaning they are coated with liquid zinc to prevent corrosion. However, this coating will eventually wear off, and the process adds to the cost and weight of the trailer.

Aluminum Boat Trailers

Aluminum boat trailers are ideal for saltwater boating due to their corrosion-resistant properties. They are also lightweight, making them easier to maneuver and more fuel-efficient. However, they are generally more expensive and not as strong as steel trailers.

Other Materials

Other materials used for boat trailers include marine-grade galvanized steel, which is often used for smaller trailers suitable for canoes and kayaks, and lightweight aluminum, which is used for simple trailers designed to transport gear and smaller watercraft like kayaks and canoes.

Boat trailer weight capacity

When considering the weight capacity of a boat trailer, it is important to take into account the weight of the boat, any gear on board, fuel, and water in the hull. This is known as the "wet weight". It is also important to ensure that the trailer has the ability to tow the weight of the boat, rather than relying on the weight listed on the spec sheet. Additionally, a buffer zone for weight-shifting surges is recommended.

The weight capacity of a boat trailer can vary depending on the type of trailer and the size of the boat. Single-axle trailers, suitable for smaller boats under 1,000 pounds, typically weigh between 200 and 600 pounds and can carry up to 3,300 pounds. Tandem-axle trailers, used for larger boats, usually weigh up to 1,000 pounds and can support boats up to 8,000 pounds. Triple-axle trailers, designed for heavy-duty boats weighing around 8,000 to 10,000 pounds, typically weigh between 1,000 and 1,600 pounds.

It is important to note that the weight of a boat trailer can also depend on the materials used in its construction. Aluminum trailers, for example, are lightweight yet strong and corrosion-resistant, making them a popular choice for those launching their boats in both fresh and brackish water. Steel trailers, on the other hand, are stronger but heavier and more prone to rust and corrosion.

When determining the appropriate weight capacity for a boat trailer, it is crucial to consider the gross vehicle weight rating (GVWR) and the gross combined weight rating (GCWR). The GVWR is the maximum weight the loaded trailer is rated to carry, while the GCWR is the maximum weight of the loaded vehicle plus the loaded trailer. By subtracting the GVWR from the GCWR, you can determine the maximum loaded trailer weight your vehicle can tow.

In addition to weight capacity, it is also important to consider the length of the trailer, the number of axles, and any additional features or options offered by the manufacturer.

Boat trailer hull length

When determining the length of a boat trailer, it is important to note that the trailer should be longer than the boat. The boat trailer should measure longer than the boat's hull length, which is different from the length on the spec sheet. The spec sheet length often includes extended features such as swim platforms, which are not attached to the trailer.

A properly fitted boat trailer should have trailer bunks that come to the edge of the hull or within a few inches over it, but never short of the hull, as this can cause damage. The bow pulpit, if the boat has one, should also be included in the length calculations.

When measuring the length of the boat, add a few feet for the engine and the trailer tongue. For boats with engines mounted on the transom, add 2 feet for the outboard and 3 feet for the trailer tongue. For boats with platform/bracket-mounted engines, add an extra 3 feet.

It is also important to consider the weight of the boat when choosing a trailer. The trailer must have the capacity to tow the weight of the boat, including the weight of the engine, fuel, water, and personal gear.

Boat trailer bunk systems

When choosing a boat trailer bunk system, it is crucial to select a material that is durable and compatible with your boat. Standard pressure-treated lumber wrapped in outdoor carpet is a common choice, but it has some drawbacks, including the use of chemicals that can corrode aluminium and galvanized trailer parts. Another option is Trex, a "green" material made from recycled plastic and wood, but it may not provide sufficient support for heavier boats.

For those seeking maximum strength and durability, cypress trailer bunks are an excellent option. Cypress is naturally resistant to rot, insects, warping, and splitting, making it ideal for boat trailer bunks. While it may be more expensive in certain regions, its longevity makes it a worthwhile investment.

When replacing or upgrading your boat trailer bunks, several companies, such as Wholesale Marine, Tie Down Engineering, and CE Smith, offer a range of replacement parts and accessories. It is important to choose a system that is compatible with your trailer and boat, ensuring a secure fit and adequate protection during transport and storage.

Additionally, proper maintenance of your boat trailer bunk system is crucial. Regularly inspect the boards for any wear and tear, and consider investing in a marine-grade carpet to protect the bunks and enhance the overall durability of your trailer.

Boat trailer bearings and hubs

Maintaining and protecting boat trailer bearings is critical, especially when the trailer is frequently submerged in water after a long road haul. Bearing Buddies, available in stainless steel or chrome, are popular bearing protectors that help prevent water washout and corrosion. Regular greasing of the bearings is essential, and it is recommended to use marine trailer bearing grease, which offers superior protection against water washout and salt water corrosion.

When it comes to hubs, cast iron trailer hubs are commonly available in SAE and Metric sizes. It is important to replace the inner and outer races or cups during hub rebuilding to maintain proper bearing tolerance. Additionally, ensuring compatibility between different types of greases is crucial to avoid adverse chemical reactions.
