What is the cruising speed and the corresponding RPM?

• A. 25 knots at 3250 rpm
• B. 28 knots at 3000 rpm
• C. 22 knots at 3500 rpm
• D. 30 knots at 3200 rpm

Answer: (A)

The speed you cruise at is tied to a midrange engine setting that balances getting you on plane with fuel efficiency and engine wear. For a 29' Response Boat–Small, a comfortable, efficient cruise usually sits in the higher end of mid-range RPM, where you still have plenty of torque to stay on plane without revving the engine toward its maximum. The pairing of 25 knots at 3250 rpm fits that typical cruise band: you’re at a steady, manageable speed with an engine load that isn’t excessive, which is ideal for everyday operation and economy.

The other options push toward unlikely combinations: cruising faster at a lower RPM would require unusual efficiency or lighter load; slower speed at a higher RPM would waste fuel and strain the engine without giving you more hull performance; and reaching a high speed at a relatively modest RPM would imply more power than the hull typically needs at that setting. In short, 25 knots at 3250 rpm aligns with the expected balance of speed and engine load for cruising.
