TowSense / Boats & boat trailers

Look beyond the boat's advertised weight.

Bring together the boat, trailer, engine, fuel, equipment and loaded tow vehicle figures.

Tow vehicle with a boat on its trailer

Suggested starting point

For a tow vehicle and loaded trailer combination, including a boat trailer. The product name says caravan; its scope also covers other trailer combinations with the required ratings and measurements.

One-off automated digital assessment, not a personal consultation. Review the required inputs before paying. Missing figures remain unknown; payment does not verify them.

Start with the whole picture

The loaded boat and trailer are one part of the picture.

Published boat weight may not describe the combination you tow. Prepare figures for the trailer, engine, fuel, batteries and equipment, together with the loaded tow vehicle.

Buying a boat package

Ask what the quoted weight includes and obtain the actual trailer and vehicle ratings.

Adding equipment

Account for batteries, fuel, fishing gear and other additions without counting items twice.

Preparing to tow

Use measurements for the actual loaded setup and confirm the coupling configuration.

What to gather first

  • Boat and trailer identification
  • Trailer ATM, GTM and other documented limits
  • Engine, fuel, batteries and carried equipment
  • Loaded tow vehicle and axle measurements
  • Actual trailer and coupling measurements
Prepare your boat-and-trailer figures

Check what each quoted weight includes before recording the package as a complete loaded trailer.

Connected vehicle and trailer reference pointsA identifies the tow vehicle axle readings, B the coupling and C the trailer axle group. These are separate measurement references.ABC

Reference diagram, not to scale. Follow the selected tool and weighing-service instructions.

A · Vehicle
Record the vehicle axle readings and whether the trailer was connected.
B · Coupling
Keep an actual coupling measurement separate from documented coupling limits.
C · Trailer
Distinguish the trailer axle-group reading from the whole loaded trailer mass.
  • Check included components

    Confirm whether the boat figure includes the engine, fuel, batteries and equipment. Keep the trailer's own information separate.

  • Gather ratings and readings

    Record documented trailer limits and actual loaded measurements separately. Include the tow vehicle's passengers, fuel and cargo.

  • Keep the same setup

    Use matching loaded vehicle and trailer readings and identify the coupling and hitch setting. Follow the selected tool's supported measurement method.

Before you continue

Is the advertised boat weight enough?

Not necessarily. Confirm which components it includes and prepare figures for the complete loaded trailer.

Does this assess launch-ramp traction or boat handling?

No. Launch-ramp performance, marine handling and dynamic towing behaviour are outside the loading assessment.

Review the boat package as a complete setup.

Start with measurements if the advertised figures do not describe everything you tow.

Have the loaded combination figures?

Review the existing towing assessment and its scope before continuing.
