The Oromarine S11 Coupe Rib of our test, which homologation’s length is less than 10 meters, captivated the eyes due to the beautiful color combinations of black tubes, console gray and orange upholstery making it stand out among all the others.
Its deck is distinguished for its large sunbathing areas, but what stands out at first glance is its beautifully designed cabin-console that gives a really sporty and aggressive character.

In the area of the bow a very large sunbed is formed whose cushions are about in the middle of the large diameter tubes. Underneath there are two large lockers that can fit all of the lifeboat equipment and several of our luggage.
A little bit further is the hard nose, which is a continuation of the bow fiberglass superstructure and has two steps on its lateral sides for access to the boat.
Its anterior part has a downward inclination and a large recess in its center where the anchor exits, to the right and left of which are two large cleats.

The beautiful console of S11 Coupe, centrally positioned leaving comfortable passageways to its port and starboard, reaches up to the bow sundeck without leaving any space between, thus increasing the useful space inside.

At the front of the console the door is leading to the small cabin. Two wooden steps lead us to the inner hallway to the right and to the left of which two benches are formed which, with the corresponding addition create a comfortable berth for two adults.
In the background there is the cabin’s toilet and two hatches that give access to the helm’s electrical installation.

The instrument panel has room for mid-sized electronic devices and the engine's multi-function gauge, properly inclined so as to inspect the indications even when driving upright.
The steering wheel is centrally positioned, having on the left the switches and the cd-radio and on the right the engines controls.
Although the windscreen is elegant enough and fits the overall console aesthetic, still does not offer great wind and spay protection to the boat's operators.

The outdoor kitchen is centrally located leaving large passageways to its port and starboard for our comfortable and unobstructed fore and aft movement. On its front part, the double helm seat is fitted having the proper distance from the steering wheel, while behind it is a large lid that reveals the sink and gas stove when lifting it. On the back of the countertop a stainless steel fridge is centrally located.

Behind the outdoor kitchen is the four-seater stern sofa, from the backrest of which the spacious aft sundeck begins, which is characterized by its large dimensions. Underneath the largest storage space of the boat is hosted that can easily be converted into a second cabin where two adults can sleep.
To the right and left of the sunbathing berth there are two gunwales lined with teak leading us to the engines’ area.

The 90cm long stainless steel brackets on which the engines are hung provide a great deal of space for a very comfortable swimming platform that extending right and left of the engines provide a huge overall surface which we greatly appreciate upon entry and exit from the boat as well as during our sea activities.

 

At sea

The S11 Coupe of our test was fitted with two Evinrude E-Tec G2 300hp outboard engines which having a 1.85: 1 gear ratio turned 15΄΄x 21΄΄ 3-blades Rebel stainless steel propellers.

Pushing the throttles forward, the engines accelerated immediately, showing us the enormous torque they deliver at low rpm.
With 250 liters of fuel and 3 crew members, the Rib was standing on plane at 2300 rpm at a speed of 13 knots.
The planning time was just 3.5 seconds with a slight rising of the bow, accelerating to 30 knots in 6.8 seconds and up to 40 knots in 9.15 seconds.

At 3000 rpm our speed was 19 knots and the fuel consumption was 2.1 liters per nautical mile, while at 3500 rpm we were running with 24 knots with the consumption staying the same.
At 4000 rpm we were traveling at 30 knots, with no significant increase in fuel consumption which reached 2.3 liters per mile.
The above figures show us that we can travel from 20 to 28 knots, getting the maximum economy of our engines, thus increasing our autonomy.

At 4500 rpm our speed reached 35 knots with a fuel consumption of 2.5 liters per mile and at 5000 rpm 40 knots burning 2.9 liters per mile.

At the wide-open throttle, the engines exceeded their maximum rpm range and reached 6200 rpm with our top speed reaching 53 knots.

Our detailed measurements are in the table below:

Looking at the numbers we recorded, we come to the conclusion that the slip values are quite good, except at low rpm due to the propellers’ dimension we were turning.

In general we can say that S11 Coupe left us very good impressions regarding its riding, showing soft navigation mainly due to its high transom deadrise that reaches 24 degrees.
It was also obvious that it can travel to distant destinations comfortably, fast and economically, without exceeding 2.3 liters per nautical mile when maintaining cruising speeds of up to 30 knots.

...keep Ribbing!
