1Key Takeaways

This document is applicable for CLASS C classified floating leisure articles for use on and in water according to ISO 25649-1 regardless of whether the buoyancy is achieved by inflation or inherent buoyant material. This document is to be applied with ISO 25649-1 and ISO 25649-2. NOTE 1 Typical products forming class C…

2Expert Interpretation

This in-depth guide explains the safety requirements and test methods for Category C towed watercraft in ISO 25649-5:2017, covering key technical specifications such as design specifications, load capacity, and residual buoyancy. It also provides professional implementation advice and risk analysis. This guide is applicable to safety compliance for high-speed water recreational equipment such as tube tow boats and banana boats.

Analysis of the core requirements of the standard

ISO 25649-5:2017 has formulated special safety specifications for Category C water towing equipment (including tube towing boats, banana boats, etc.). The main technical control points include:

Key indicators of structural design

Items Category C1 requirements Category C2/C3 requirements
User space Enclosed cockpit, minimum seat length of 60cm for children No specific size restriction
Grip device
  • Eight heading tests (headwind, crosswind, etc.) each lasting 10 minutes
  • Emergency braking simulation (sudden throttle drop to idle)
  • Re-boarding test after intentional capsizing
  • Verification of buoyancy maintenance in the event of single-chamber failure

The test must be collectively judged by a professional assessment team based on nine preset pass/fail criteria.

Technology Evolution Analysis

Compared with traditional water equipment, this standard highlights the special considerations for high-speed dynamic working conditions:

  1. Elasticity requirements for traction systems (elongation <4%)
  2. Category C3 equipment requires flight testing
  3. Introduction of quick release system (see Appendix A)
  4. Mandatory visual signal system (Chapter 8)

Implementation Recommendations

Key Points for Manufacturers

  • Marking of the maximum number of passengers and weight range on the product
  • The instruction manual must include 10 mandatory warning signs (example in Figure 1)
  • Provide a complete diagram of hand signals (Figure 2-11)

User Safety Tips

  • Users of Category C3 equipment must be at least 14 years old
  • Protective clothing and helmets must be worn (mandatory for Category C3)
  • Putting limbs through the traction rope fixing system is prohibited
