How Big a Boat Can a Honda Ridgeline Tow? Use Weight, Not Length
Automotive Research, ASE Master Technicians & Fact-Checking
A Honda Ridgeline’s boat-towing limit cannot be converted into one safe boat length. For the 2021 and 2022 Ridgeline, Honda lists a maximum towing capacity of 5,000 pounds. The number that matters is the fully loaded combined weight of the boat and trailer, plus tongue load and the weight of people/cargo in the truck, not whether the boat is 16, 18 or 22 feet long.
The previous AutoZonic article incorrectly turned the 5,000-lb rating into universal boat-length claims such as “16–18 feet” and “up to 22 feet.” Boats of the same length can differ dramatically in hull, engine, fuel, batteries, gear and trailer weight.
Ridgeline towing baseline
Honda’s 2021 documentation states:
- Maximum towing capacity: 5,000 lb
- Integrated trailer hitch: standard
- 7-pin connector: standard
- High-capacity radiator and dual high-power fans: standard
- Heavy-duty transmission cooler: standard
- Premium unleaded recommended when towing more than 3,500 lb
What weight should a boat owner calculate?
Start with the trailer’s real loaded weight, not the boat manufacturer’s dry hull weight. Include:
- boat hull
- engine/outboard
- trailer
- fuel
- batteries
- water where applicable
- anchors, coolers and fishing/watersports gear
- any equipment permanently mounted to the boat
If that loaded boat-and-trailer combination approaches the vehicle’s maximum rating, passenger and cargo weight in the Ridgeline becomes even more important.
Tongue weight matters too
Honda explains that tongue load is the downward load a fully loaded trailer places on the hitch and notes that it should not exceed 15% of total trailer weight. Too much tongue load can reduce front-tire traction; too little can contribute to trailer sway.
Do not choose a boat simply because total trailer weight is below 5,000 lb. Confirm tongue load, payload and all owner-manual limits for the exact truck.
Honda’s own boat-towing example
Honda’s 2021 Pickup Truck 101 material gives a concrete example: an RTL-E can tow a boat and trailer with a combined weight of 4,750 lb and a maximum tongue load of 600 lb while accommodating four occupants under the assumptions Honda used in that example.
That is useful as an illustration, not a universal allowance for every owner. Actual passengers, gear and accessories can change available capacity.
Why boat length is a poor shortcut
A lightweight aluminum fishing boat and a heavily equipped fiberglass wake boat may have similar lengths but very different trailer weights. Pontoon layouts also vary widely. Therefore, “what size boat?” should be answered with the trailer’s scale/loaded weight and the Ridgeline’s model-year ratings.
Before towing a boat with a Ridgeline
- Confirm the exact Ridgeline model year and towing rating.
- Know the actual loaded trailer weight.
- Check tongue load and payload.
- Include passengers and cargo in the vehicle-load calculation.
- Confirm trailer brakes, lighting, tires, safety chains and coupler condition.
- Use the correct hitch/ball rating and Honda’s 7-pin connection requirements.
- Follow the model-year owner’s manual and local trailer-brake laws.
