How Much Does A Pontoon Boat Weigh?

Introduction

Wondering how much a pontoon boat weighs? Knowing the answer is essential for safe towing, storage, and on-water performance. Most pontoons weigh between 2,000 and 3,000 pounds, though sizes and features can push that number much higher. In this article, we’ll explain dry vs wet weight, compare real-world models, and show you how different factors—like motors, fuel, and accessories—impact total weight. You’ll also learn practical tips for calculating towing requirements and choosing the right pontoon for your needs.

Understanding Pontoon Boat Weight Basics

What Is Dry Weight vs Wet Weight?

When people ask about pontoon boat weight, the first distinction is usually dry weight versus wet weight. Dry weight is the simplest number to understand—it represents the boat itself without fuel, passengers, or cargo. Manufacturers list this figure so buyers can easily compare models side by side. Wet weight, on the other hand, is the number you’ll actually feel when towing or using the boat. It includes a full fuel tank, passengers, and every piece of gear on board. Since fuel alone adds significant pounds—about six pounds per gallon—the difference between dry and wet weight can be hundreds of pounds. Add coolers, fishing equipment, and water toys, and the gap grows even wider.

Why Does Pontoon Boat Weight Matter?

Pontoon weight matters because it directly affects safety, handling, and convenience. If your boat is heavier than your tow vehicle can handle, you risk straining the transmission, overheating brakes, or even causing dangerous sway on the highway. Storage is another concern—many boat lifts and docks are rated for specific capacities, and exceeding them can damage both the lift and the boat. On the water, extra pounds reduce speed, increase fuel consumption, and make handling less responsive, especially in choppy conditions. Safety is the final piece of the puzzle: an overloaded pontoon sits lower in the water, making it more vulnerable to swamping or tipping in rough waves. Knowing the actual weight of your pontoon, both dry and wet, ensures you avoid these issues and enjoy smoother, safer outings.

Average Pontoon Boat Weight (Quick Estimates)

General Rule of Thumb for Estimating Weight

One of the easiest ways to estimate pontoon weight is by using a simple rule of thumb. Multiply the boat’s length in feet by 100 to 120 pounds, and you’ll have a reasonable starting point. For example, a 20-foot pontoon usually falls between 2,000 and 2,400 pounds before fuel, passengers, or accessories are added. This formula isn’t perfect, but it gives buyers a quick way to compare different sizes without needing every specification sheet.

Typical Weight Ranges by Boat Size

Pontoon boats are not all built the same, but weight usually aligns closely with size. Small pontoons, typically between 12 and 19 feet, weigh anywhere from 1,000 to 2,000 pounds. They are light enough for easier towing and often chosen by casual anglers or families with smaller vehicles. Medium pontoons, which span roughly 20 to 35 feet, average 2,000 to 3,500 pounds. This group balances comfort and performance, offering more seating and features without becoming too heavy to tow. Large pontoons, stretching beyond 35 feet, can weigh 3,500 pounds on the low end and more than 8,000 pounds for luxury models. These heavier boats provide stability and space, but they demand powerful vehicles and stronger trailers.

• Small pontoons (12–19 ft): 1,000–2,000 lbs

• Medium pontoons (20–35 ft): 2,000–3,500 lbs

• Large pontoons (35+ ft): 3,500–8,000+ lbs

Factors That Affect How Much a Pontoon Boat Weighs

Pontoon boats can vary a lot in weight. Several factors combine to determine how heavy it gets. Understanding them helps when choosing, towing, or storing your boat.

Length and Size of the Boat

Longer pontoons usually weigh more. A 16-foot model may be light, while a 26-foot version can double that weight. Width and deck size also matter—they add bulk even if the hull stays the same.

Construction Materials (Aluminum vs Fiberglass)

Aluminum pontoons are common—they’re lighter and resist corrosion. Fiberglass decks feel sturdier but add extra weight. Many boats mix materials, so it’s a balance between durability and weight.

Motor Size and Horsepower

The engine changes everything. A 40 HP outboard is lighter than a 150 HP model. Bigger motors require more support structures, which adds pounds fast.

Fuel Capacity (6.1 lbs per gallon)

Fuel isn’t just volume—it weighs something. Each gallon adds roughly 6.1 pounds. A 30-gallon tank can tack on about 180 pounds alone. Fill it up, and it’s even heavier.

Passenger and Cargo Load

People, coolers, fishing gear—they all matter. Each adult passenger adds around 150–200 pounds. Cargo can vary from a few hundred pounds to over a thousand, depending on your trip plans.

Extra Features and Accessories

Canopies, fishing chairs, stereo systems, and slide ladders all add weight. Even small items stack up. Consider them when calculating total weight for towing or docking.

Pontoon Boat Weight Examples by Popular Models

Pontoon boats come in all shapes and sizes. Seeing actual models helps us understand how their weight can vary. Let’s break them down by size categories.

Small Pontoon Boats (14–16 ft)

These boats are light and easy to tow. Perfect for fishing or short trips. Examples include:

They’re compact, handle easily, and usually fit in smaller storage areas.

Mid-Sized Pontoon Boats (20–26 ft)

A step up in size and comfort. They carry more passengers and gear. Popular models:

These boats need more towing power. They feel more stable on the water, too.

Large & Luxury Pontoon Boats (30 ft+)

Big pontoons bring space, luxury, and weight. They often include extra features and high-end finishes:

They’re great for parties, overnight trips, or cruising with friends. Towing requires a heavy-duty vehicle.

Pontoon Boat Weights by Type

Pontoon boats vary not only by size but also by type. Each type has typical weight ranges, helping you pick one that suits towing, storage, and usage.

Standard Pontoons (~2,100 lbs dry)

These are the classic models. Simple, reliable, and moderately light. Perfect for family outings or short cruises.

Leisure/Entertainment Pontoons (similar to standard)

Built for fun and comfort. They add a few amenities but weigh close to standard pontoons. Great for casual trips with friends.

Sundeck Pontoons (~3,100 lbs+)

Sundecks expand space and seating. They’re heavier because of larger decks and reinforced hulls. Ideal for long, relaxed days on water.

Fishing Pontoons (1,800–2,100 lbs)

Designed to be light and maneuverable. Less weight means easier handling and shallow water access. Anglers love their simplicity.

Performance & Sport Pontoons (3,000–3,500 lbs+)

High-speed and sporty. Bigger engines and extra reinforcements add weight. They’re fun, but require more towing power.

Luxury Pontoons (3,000–5,000 lbs+)

These include top-end features, electronics, and premium finishes. Heavy but very comfortable. Often used for parties or long trips.

Value Pontoons (1,450–2,000 lbs)

Budget-friendly models. Simple, lightweight, and easy to tow. They may lack extra features but get the job done efficiently.

How to Calculate Your Pontoon Boat’s Weight

Knowing your pontoon’s weight helps with towing, storage, and safety. It’s easier than it sounds if we break it into steps.

Step-by-Step Calculation

We can estimate total weight using a few key numbers:

1. Dry weight – Check manufacturer specs.

2. Fuel weight – Multiply tank gallons by 6.1 lbs per gallon.

3. Motor weight – Usually 200–700 lbs depending on size.

4. Trailer weight – Average is about 1,200 lbs.

5. Gear, passengers, accessories – Estimate what you plan to carry.

Example Calculation (22 ft Pontoon with 115 HP Motor)

Here’s how it looks in practice:

We start with the dry weight, then add fuel, motor, trailer, and gear. The total gives a realistic towing weight.

This approach works for any pontoon model, small or large. Adjust numbers based on your actual tank, motor, and load.
