The Idea Marine 100 demonstrates that planing hulls achieve optimal fuel efficiency (2.9 L/mile) at cruising speeds around 24 knots, with fuel consumption remaining relatively stable across different speeds due to the hull's ability to transition efficiently between displacement and planing modes, while maintaining excellent visibility and stability through features like minimal bow rake and wide beam design.

[ENG] Idea marine 100 - THE TEST
Added:Well, friends, we're off the coast of Naples aboard the Idea Marine 100 powered by a pair of 300 horsepower our Yamahas. Today we're sailing offshore.
As you can see from the front camera and even from the external camera, the weather conditions are ideal for a test as there's a short wave rising. We're shooting this video in the middle of an autumn afternoon. So, the classic Mistral wind is starting to blow here in the Gulf of Naples. So, it will be an excellent test bed for testing the performance of this hull in combination with these two engines, which represent intermediate power levels for their thrust. We'll see how it performs under these conditions.
We're sailing on 40% fuel with two people on board and a 50% water tank.
Here, I'm currently idling at 500 revolutions per minute, speed 2.6 6 knots and a total fuel consumption of 5.5 L. So, let's get cruising.
I have the throttles in sync with the safety cut off securely fastened as you see on camera since we always sail in complete safety.
However, we've already tested this boat privately in slightly more stressful conditions with strong winds and 70 cm waves. So, we already know we're sailing well protected inside the helm station as well as inside the cockpit since there are also stern gates that provide full protection as we saw in the onboard presentation.
900 revolutions per minute, currently 4.8 knots, consumption 10 L per hour, but we push more. The hull is equipped with skids, so they'll obviously provide support when exiting from the water. And these engines in particular have steerby wire electro-hydraulic steering. So we can easily control the entire helm with just one hand. And we can also perform maneuvering operations using the joystick. So we just have to indicate which direction to push the boat and the engines will take care of themselves. We continue pushing. 1,600 revolutions, 7.7 knots. Consumption 20 L/ hour. We push more.
We can hear the roar of the engines as they begin to push, working harder to get the boat out of the water. We're raising the bow with a slight nose up, indicating we're entering the water with a planing motion. But notice the visibility, which remains excellent as the bow's rake is minimal, so we're not experiencing any difficulty. The windshield protects us up to eye level.
So, we have full control of what's happening around us. Even at the stern, as you can see from the bow, only the struts are discharging laterally, so visibility is at its best.
25,500 revolutions per minute, 10.2 knots. The wake is forming at the stern, but so we immediately accommodate the engine's demands to work as best as possible.
Trim still fully down, and we begin to exit the water. 12 knots consumption, 4 L per mile overall, 49.3 L.
Then gradually it optimizes precisely because we are coming out of the water.
So intermediate behavior.
We go up again. Look how we start to relax. The engines roar there in the stern.
3,600 revolutions per minute, 15.7 knots. But now the bow is starting to level out on the horizon. And we relax without touching the throttle. We reach 17.5 knots. But watch the indicator continue to climb precisely because the hull is starting to work at its best. So economical cruising condition currently still 3,600 revolutions per minute. 20 knots. The bow is lowered further. Look.
And the consumption also optimizes. We reach an average of 3.1 L per mile at 22 knots. Still 3,600 revolutions per minute. I only slightly adjust the trim to reduce the wetted surface. And we reach 24 knots 23.5 without touching the throttle.
Consumption unchanged at 3 L per mile.
So cruising speed is truly optimal at 24.3 knots. And consumption has been optimized to 2.9 L per mile. At this speed, we lower the trim only slightly and use this steering system for a straight turn. Look here. The hull has a wide bull work, so I can expect a greater heel, but this is obviously not a pleasure tack condition.
We are turning more tightly. Look here at the linear turning radius. We are slowing to 19 knots, 20 knots. Engines are working to compensate. Now, let's cross our waves. Look, the impact is really well absorbed.
And above all, we don't hear any noise from the onboard structures despite this very generous T-top. And now, let's cross our waves, too. Let's see if the boat has any signs of nose diving. Look, let's try to stress her on the bowl. We lean.
I could also choose to correct the trim using the automatic trim tabs here, but at the moment, we're not touching them at all.
So, we return to the center line with the rudder at 4,100 revolutions per minute, 27.3 knots. Fuel consumption is 89 L per hour, so 3.2 L per mile. Truly excellent fuel consumption practically unchanged. It has a more sustained cruising speed. And above all, look at the comfort on board. Truly at the highest levels for this type of boat with these volumes. Let's go up.
Hear the roar of these engines. We're exiting the cruising range. Look how level we remain on the horizon.
>> 32.5 knots. Obviously, we're going outside the cruising range. 3.9 L per mile overall.
But look how well this hull works. I raised the trim to reduce and make the skids work even harder.
33 knots. Consumption 3.9 L per mile, 4,800 revolutions. But let's see where they take us. We push the throttle all the way down. Engines roar. 5,500 revolutions per minute. 5,600 revolutions per minute. 38 knots. 39 knots. Consumption 5 L per mile. The engines are working at full throttle. 40 knots. 40.7. I raise the trim. 60%. 41 knots. 41.1.
>> 41.3 41.5 knots. But now we're going down slightly and making a left turn.
Don't try this at home. Currently 37 knots decreasing. Look here.
>> We're looking for a sportier behavior from this boat. We're bringing out the racing soul. If you'll pardon the expression, even though it's a boat born for the cruising, obviously this is a different situation. Turning at 33 knots. Look at how we're moving along the bull work. Visibility remains more than good. But now all we have to do is shift into neutral and see how many seconds these engines take us out of the water. How many seconds we reach top speed.
So here we are in neutral. The rudders are already centralized. So all I have to do is count. 3 2 1 go.
>> Throttle fully down. Hear the roar.
We're already out of the water. 12 knots 15 18 20 23 Look how the bow levels out.
30 knots 32.9 34 I raise the trim 5,500 revolutions 200 L/ hour total 39.4 4 knots 40 kn 41 kn 4106 >> we reach 42 knots at 6,000 rpm with a total consumption of 4.9 miles.
>> So what can I say with this last turn?
All I have to do is return to port.
This is the idea marine 100 powered by a pair of 300 horsepower Yamahas. It's a boat I recommend to anyone who primarily wants tons of space on board, as this size offers practically everything for cruising.
The cabin is perfectly usable for four people. There's a separate bathroom, but above all, we've seen how the outside area allows for a proper sund deck in the stern area, and when purchasing, we can also configure different layout solutions to customize the boat in every way.
As for navigation, we've seen how we managed to maintain an optimal cruising range. As in this case, with a speed of 23.7 knots and a fuel consumption of 2.7 L per mile, the impact on the waves is really well managed and especially during turns, the top side follows the radius of the curve, but we don't lean excessively and visibility remains truly excellent.
Furthermore, with this particular steering system, we can steer without any problems. So we can handle it exactly as if we were in a car. And with the wide bull works, even less experienced people can easily fit anywhere on the boat, making it ideal for rentals, too. So dear friends, as always, if you enjoyed the video, I invite you to subscribe to the YouTube channel and Facebook page. Leave a like and tag people you think might be interested. And as always, for all future videos, see you here on the Sea Team.
