AvatarByFrancis Mortimer Boats & Vessels

When it comes to transporting a pontoon boat, one of the most common questions boat owners ask is, “How tall is a pontoon boat on a trailer?” Understanding the overall height of your pontoon boat when it’s mounted on a trailer is crucial for safe and hassle-free travel. Whether you’re navigating under bridges, passing through tunnels, or simply loading and unloading at the marina, knowing this measurement helps prevent unexpected obstacles and ensures compliance with road regulations.

Pontoon boats are known for their spacious decks and stable rides, but their unique design also influences their height once trailered. Factors such as the size of the pontoons, deck height, and trailer type all contribute to the total height, which can vary significantly from one model to another. This makes it essential for owners to have a clear idea of their specific setup before hitting the road.

In the following sections, we’ll explore the typical height ranges of pontoon boats on trailers, what influences these dimensions, and practical tips for measuring and managing your boat’s height during transport. Whether you’re a seasoned boater or new to pontoon ownership, this guide will equip you with the knowledge you need to travel confidently and safely.

Factors Influencing the Height of a Pontoon Boat on a Trailer

The overall height of a pontoon boat on a trailer is influenced by several critical factors. Understanding these can help in planning for transportation, storage, and navigating under bridges or through tunnels.

One major factor is the size and design of the pontoon boat itself. Pontoon boats vary widely in length, width, and deck height. Larger boats with higher decks or taller railings will naturally sit higher on a trailer. The pontoons (the flotation tubes) also contribute to the base height of the boat, affecting how high it sits off the trailer bed.

The type and design of the trailer play an equally important role. Trailers come with different frame heights, wheel sizes, and suspension systems. For instance, trailers equipped with larger tires or multi-axle configurations might raise the boat higher off the ground. Additionally, some trailers are designed with adjustable bunks or rollers that can affect how snugly the boat sits, thereby impacting overall height.

Other considerations include:

  • Motor height: Outboard motors mounted on the transom can add significant vertical height, especially if the propeller or anti-ventilation plate extends above the pontoon deck.
  • Accessories and equipment: Items such as bimini tops, radar arches, fishing towers, or antennas can increase the maximum height of the boat on the trailer.
  • Load distribution: How the boat is positioned and secured on the trailer can slightly affect height, especially if the boat tilts or shifts during loading.

Typical Height Ranges for Pontoon Boats on Trailers

Pontoon boats generally have a moderate height when loaded onto trailers, but this can vary based on the factors above. Typical height ranges help boat owners anticipate clearance requirements.

Pontoon Boat Size (Length) Average Height on Trailer (feet) Notes
16 – 20 feet 7 to 8 feet Smaller pontoons with minimal accessories
21 – 24 feet 8 to 9 feet Mid-sized boats with standard motors
25 – 28 feet 9 to 10 feet Larger models, often with bimini tops
29+ feet 10+ feet Custom or fully equipped boats

These measurements include the boat itself, trailer frame, and typical outboard motor height, but exclude any additional removable accessories. When planning for transport or storage, it’s wise to measure your specific setup to ensure safe clearance.

Measuring Your Pontoon Boat Height on a Trailer

Accurately measuring the height of your pontoon boat on its trailer is essential for compliance with road safety regulations and for avoiding obstacles during transport.

To measure:

  • Use a tape measure or laser distance meter.
  • Position the boat and trailer on level ground.
  • Measure from the ground directly to the highest fixed point on the boat or trailer. This includes motors, antennas, and any permanent accessories.
  • Double-check measurements at multiple points if your boat has uneven features like a raised fishing tower.
  • Record the height and compare it with clearance limits for bridges, tunnels, or storage facilities.

Tips for Reducing Height When Transporting a Pontoon Boat

If your pontoon boat on a trailer is too tall for certain routes or storage spaces, there are several strategies to reduce its overall height:

  • Remove or fold down accessories: Bimini tops, radar arches, and antennas are often designed to fold or detach to lower the profile.
  • Tilt or trim the outboard motor: Many outboard motors have a tilt feature that allows you to angle them upward or backward, reducing height.
  • Use low-profile trailers: Some trailers are designed with lower frames or smaller wheels, which can help reduce total height.
  • Distribute weight evenly: Proper loading ensures the boat sits level and at the intended height on the trailer.
  • Use bridge plates or ramps: When loading or unloading, these can help avoid damage to the motor or trailer but do not impact overall height during transport.

By carefully managing these factors, pontoon boat owners can safely navigate height restrictions and protect their investment during transport and storage.

Typical Height of a Pontoon Boat on a Trailer

The overall height of a pontoon boat when mounted on a trailer varies depending on several factors, including the size of the boat, the trailer design, and any additional equipment or accessories attached. Understanding these variables is crucial for transportation planning, storage, and complying with road regulations.

The height measurement generally refers to the distance from the ground to the highest point of the boat or trailer assembly when loaded and ready for transport. This highest point is often the top of the pontoon boat’s canopy (if equipped), radar arch, or any mounted accessories such as antennas or navigation lights.

Factors Influencing the Height

  • Boat Length and Design: Larger pontoon boats tend to have higher profiles, especially models with multi-level decks or tall rails.
  • Trailer Type: Standard pontoon trailers typically have frame rails supporting the pontoons, adding a few inches to the overall height.
  • Accessories and Equipment: Bimini tops, towers, and mounted electronics increase the height.
  • Tire Size and Suspension: The trailer’s tire diameter and suspension height affect ground clearance and total height.

Average Height Ranges

Pontoon Boat Length Approximate Height on Trailer Notes
16 to 20 feet 7 to 8 feet (84 to 96 inches) Smaller pontoons with minimal accessories, often no canopy
21 to 25 feet 8 to 9.5 feet (96 to 114 inches) Mid-sized pontoons, may include Bimini tops or radar arches
26 to 30 feet 9 to 10.5 feet (108 to 126 inches) Larger models, frequently equipped with towers or full canopies
30+ feet 10 to 12 feet (120 to 144 inches) Extra-large pontoons with multi-level decks and extensive accessories

Considerations for Transport and Storage

When transporting a pontoon boat on a trailer, height restrictions imposed by road authorities must be observed to avoid fines or damage. Most states in the U.S. set maximum allowable heights for vehicles and trailers, typically around 13 feet 6 inches (162 inches). Pontoon boats on trailers generally fall well below this limit but should still be measured carefully, especially if aftermarket accessories increase height.

  • Measure at the highest point: Include antennas, lights, and folded or extended canopies.
  • Check local and interstate regulations: Height limits can vary by region and roadway type.
  • Use caution when entering garages, underpasses, or low-clearance areas: Pontoon trailers can unexpectedly exceed standard clearance heights.
  • Consider trailer modifications: Adjustable or low-profile trailer designs can reduce overall height.

Tips for Reducing Height

  • Fold or remove canopies and towers: Many Bimini tops can be collapsed to significantly reduce height.
  • Remove detachable accessories: Portable antennas or fishing rod holders can be taken off before transport.
  • Choose a trailer with low-profile bunks or rollers: These can lower the boat’s resting height on the trailer.
  • Lower tire pressure if recommended: This can marginally decrease overall height by reducing suspension height.
