Reverse 6.60 : A simple and efficient open hull

As we left the pontoons of the Moulin Blanc harbor in Brest for the Amares 6.60 trials, the conditions were favorable. The wind is light, barely 5 to 7 knots. We cast off, taking care to keep some speed to maneuver. The shallow draft of the boat, associated with an outboard motorization requires to be vigilant to keep the control of the trajectory in reverse.

We then head to the fuel dock. Some confusion about the fuel requirements keeps us from concluding the operation. Indeed, Yamaha recommends SP98, whereas only SP95 is available at the pump. After confirmation, only the ethanol content counts to avoid too much condensation in the tanks. Nevertheless, we note the ease of filling in the tank in front of the console, well ventilated.

We leave the harbor at a slow pace. The thin bow, under the step, allows to keep a limited wake, avoiding to disturb the boats at the pontoon. After a few adjustments to the electronics, it is time to test the boat's speed. The tidal coefficient is low, and the current limited. The waves are almost non-existent. The conditions are ideal for the readings.

Well seated, perhaps a little high for small people, the piloting is easy. The Reverse 6.60 is equipped with a Yamaha engine of 150 HP, the recommended power, with a tank showing only about 30 liters of fuel. We are 3 on board. The boat lifts off in an instant, from 3,000 rpm. In 5 seconds, we reach 20 knots, the wide redan deflecting efficiently the wake.

Between 4,000 and 4,500 rpm, the boat reaches its cruising speed of 25 knots. The consumption is then 30 L/h. The autonomy with a 100L tank is thus slightly above 3 hours.

By pushing the revolutions, the Reverse 6.60 reaches 33 knots at 5400 rpm. The consumption is then 62 L/h.

If the water level did not allow to validate the passage in the chop, the strong volumes in the front, above the step should allow it to remain quite dry. When turning, the heel remains reasonable and the wide step holds the water well, preventing the boat from skidding. Finally, another safety element, the anti-skid paint on the deck also catches the water, effectively preventing the risk of the aluminum skating rink effect!
