Which is/are the consequences when your tug reduces speed to shorten tow?

🔍 Key Concepts

• Behavior of a tow when the tug reduces speed or stops engines • Effect of momentum and inertia on the tow relative to the tug • Relationship between strain on the hawser and the actual distance between tug and tow

💭 Think About

• When the tug suddenly slows, what does the tow’s momentum make it want to do relative to the tug? • How does reduced speed affect the catenary (sag) of the towing hawser in the water? Could it change the risk of bottom contact? • Does ‘shortening the tow’ always physically pull the tow closer, or can it mainly affect the strain and catenary shape instead?

✅ Before You Answer

• Compare what happens to tow momentum versus tug speed • Visualize the shape of the hawser at high strain vs. low strain (more straight vs. more sagging) • Check if being "in irons" is a realistic condition for a tug on a hawser under power or if that phrase usually applies to a different type of vessel/condition

Question 1 of 27070

Which is/are the consequences when your tug reduces speed to shorten tow?

The towing hawser may drag the bottom and put the tug in irons

The tow may continue its momentum and overtake the tug

The length of the tow gets shorter as the strain is reduced

All of the above
