How Much Does a Pontoon Boat Weigh? Complete Weight Guide (2026)

Quick Answer: A pontoon boat typically weighs between 1,500 and 4,500 pounds (680-2,040 kg) for the boat alone. Small 16-foot pontoons weigh around 1,500-2,000 lbs, mid-size 20-22 foot models weigh 2,200-3,200 lbs, and large 24-28 foot pontoons weigh 3,500-4,500 lbs.

What Affects Pontoon Boat Weight?

Hull Material and Construction

– Aluminum pontoons (tubes) are standard — lighter than fiberglass hulls
– Tube diameter matters: 23-inch tubes are lighter than 25-inch or 27-inch tubes
– Deck material: Marine-grade plywood vs. composite decking (composite is heavier but more durable)

Engine Weight

The motor adds significant weight:
– 90 HP outboard: ~350 lbs
– 150 HP outboard: ~475 lbs
– 250 HP outboard: ~600 lbs
– Twin engines: double the above

Fuel

– Gasoline weighs about 6.1 lbs per gallon
– A 30-gallon tank (full) adds ~183 lbs
– A 50-gallon tank (full) adds ~305 lbs

Gear and Accessories

Don’t forget to account for:
– Trailer: 800-1,500 lbs
– Bimini top: 30-50 lbs
– Furniture and seating: 200-400 lbs
– Coolers, fishing gear, water toys: 100-300 lbs
– Battery(ies): 40-65 lbs each

Passengers

The U.S. Coast Guard calculates passenger weight at 185 lbs per person for capacity ratings. A fully loaded 12-person pontoon carries over 2,200 lbs just in people!

Total Towing Weight: What You Really Need to Know

When towing, add everything together:

Example: 22-foot pontoon
– Boat (dry): 2,800 lbs
– Engine: 475 lbs
– Trailer: 1,100 lbs
– Fuel (30 gal): 183 lbs
– Gear: 200 lbs
– Total towing weight: ~4,758 lbs

This means you need a vehicle rated to tow at least 5,000 lbs — a mid-size SUV or truck, not a sedan.

Popular Pontoon Brands and Their Weights

• Bennington 22 SX: ~2,650 lbs (boat only)
• Sun Tracker Party Barge 22: ~2,400 lbs (boat only)

• Avalon 2485 LSZ: ~3,400 lbs (boat only)

*Note: Weights vary by model year and options. Always check the manufacturer’s specifications for your exact model.*

Why Boat Weight Matters

Towing Safety

Exceeding your vehicle’s towing capacity is dangerous and illegal. Always know your total weight.

Performance

Heavier boats need more horsepower to achieve the same speed. A good rule of thumb: you need about 25-40 lbs of boat per horsepower for decent performance.

Fuel Efficiency

Heavier boats burn more fuel. Every extra 500 lbs can reduce fuel efficiency noticeably.

Trailer Requirements

Your trailer must be rated for the boat’s fully loaded weight. Undersized trailers are a common and dangerous mistake.

How to Find Your Boat’s Exact Weight

1. Check the capacity plate — usually mounted near the helm, shows max weight capacity
2. Manufacturer’s website — look up your exact model and year
3. Owner’s manual — lists dry weight specifications
4. Weigh it — truck stop scales (CAT scales) can weigh your boat and trailer combo

Conclusion

Pontoon boat weights range from 1,500 lbs for small models to over 5,000 lbs for large luxury tritoons. When calculating what you need to tow, always add the trailer, fuel, gear, and passengers to the boat’s dry weight. Knowing your total weight keeps you safe on the road and ensures your vehicle is up to the task.
