It’s already been 10 years since Seafighter 36 Cabin first appeared in the market, immediately gaining a prominent position amongst the mega-ribs, mainly due to its aggressive sport line and its intense nautical character, greatly combined with a wonderfully designed cabin.

It was a matter of time, therefore, for Seafighter 36 Cabin to acquire so quickly its own fan club and carry out its own successful course.

Behind every successful boat, there are people who have devoted hundreds of hours with inexhaustible passion of study, design and sea trials, translating their long experience and know-how into a high level product.

One of them is Petros Karamichalis, who managed to create a versatile Rib aimed for those who wish to live autonomously at sea for many days. His constant search has driven him each time to improve and upgrade, creating a boat that stands out for the excellent quality of construction and finishing, while the design of the cabin and its deck is perfectly adapted to our needs, offering high level ergonomics and functionality.

So 36 Cabin has undergone a number of modifications concerning both the deck and its hull, resulting in optimization of its performance in terms of fuel consumption, cruise speed and ride quality.
It runs on a deep-V hull characterized by the presence of two ventilated steps and two spray rails per side, the upper of which runs all the length of the hull, while the 24 degrees of deadrise at the transom guarantee soft cruising.

On deck

It is a fact that we spend most of our time in the sea anchored in an idyllic bay, enjoying the enchanting waters, the hot sun lying comfortably on the cushions or relaxing in the coolness of the cabin perfectly tuned in the lullaby of our hull’s rock.

Focusing on these lovely moments, Seafighter 36 Cabin offers any comfort in its spacious spaces, while ensuring our easy and unobstructed movement on the deck. With the only exception of our passage from the cockpit to the superstructure of the cabin where we would like to see an extra step or a proper configuration of the side gunwale, the deck of 36 Cabin stands out for its great passageways and its generous sundecks.

The superstructure of the cab is very well designed, maintaining a low profile that neither does it not spoil the clean and sporty lines of the boat nor it does not sacrifice its rich interior spaces. The front part of its roof, which is just above the double berth, is slightly lower than the top of the tubes, and with the addition of the cushion, it turns into a huge sunbathing area that can accommodate several people. Centrally located, the large hatch provides the necessary ventilation and cabin illumination.
Further on, at the same level with the roof of the cabin, a large hatch gives access to the windlass that is internally positioned, leaving an absolutely free field ideal for both comfortable entry and exit from the boat as well as our uninterrupted movement or long-distance diving.

One of the strongest points of the Rib is the interior of its cabin, which is characterized by the presence of two spaces which can be easily separated from one another by the use of a simple curtain.
By opening the sliding door which is located to the port of the helm, two tilting wooden stairs, lead inside which when lifting up give access to the bilge pumps.

The first image you are faced with is certainly impressive, as a huge space spreads ahead, while the wide headroom with 1.63m of height and 1.40m of length gives you the feeling that you are on a much larger boat.
On the left there are two very useful cabinets while on the right, the wooden door leads to the independent space of the bathroom with dimensions: 0.98m x 0.90m x 1.66m.

Forward, facing positioned, there are two sofas that can be converted into a comfortable bed for two children, especially useful for four-member families.
In the background, a great interior space is formed, which with a length of 2.05m, a maximum width of 1.67m and a height of 0.81m, accommodating the main bed, under the cushions of which there are two storage spaces where it can fit all the necessary equipment of the cabin.

Particularly well-designed and functional, the multi-level instrument panel is having the right inclination for its direct inspection, providing also plenty of space to accommodate even the largest navigation devices.

Centrally located there is the Lowrance's 12inch GPS, around of which, and very well arranged, the engine instruments, the electric switches and those of the bow and stern windlass as well as the trim tabs are positioned.
The steering wheel is at the right height and has the corresponding tilt while the engines’ controls are right and slightly higher to ensure a comfortable and rest position for the operator's hand.

The helmseats are independent and equipped with hydraulic suspension system and height-adjusting, providing full lateral support, which we will especially appreciate when turning abruptly. They are supported on the front surface of the polyester construction of the wet-bar and on the T-Top’s stainless steel base, having the appropriate distance from the console and the steering wheel, offering great comfort in rib handling by the operator.

The sleek, stainless steel T-Top is very well designed and offers the necessary protection, harmoniously matching with the character of the boat, while it can be used as a handle for our support in our path towards the bow.

Just behind the helmseats there is the wet-bar, which is fully equipped with a sink, a gas stove and a fridge. On the back side there is a large reclining wooden table that serves the people seating on the stern sofa while it is also very useful for preparing food.

To the port and starboard of the wet-bar large passageways with a width of 45 cm are formed and together with the large free space between the wet-bar and the four-seater sofa (1.88m x 80m) ensure great freedom of movement for the passengers.

The aft sofa has a large independent storage where the boat's direct use equipment can be fitted. A removable cushion, similar to the sundeck, is formed in the middle, creating a comfortable, 31cm of width, passageway leading to the swimming platform.

By lifting the aft sundeck the huge storage space housed underneath is revealed, which can be formed in a second cabin, measuring 1.93m x 1.10m, thus increasing the number of people who can spend the night on the boat.

A wide stair leads to the swimming platform ensuring a large free surface for our activities, and with the corresponding addition on the engine’s basin it can become even bigger.
On the port side we find the recessed bathroom ladder and two beautifully placed stainless handles that facilitate our entry and exit from the sea, while on the starboard is the aft windlass.

At sea

I took my position behind the steering wheel and pushed the throttle levers forward, up to the point where the rev counters showed 3300 rpm. I trimmed slightly the bow, the GPS was constantly showing 24.3 knots and the engines were drinking 72 litters per hour. I liked so much what I was feeling and I whispered to the manufacturer who was sitting in the co-driver's seat, that I would let it travel to these rpm for a long time as we would be discussing to each other.

I do not know if I needed it at that moment, but I really enjoyed our cruise at this speed, and of course, obviously responsible for that was Seafighter 36 Cabin.
The boat hull seemed to maintain a very good cruising angle despite the low engine rpm, allowing me to have a great view towards the bow which nicely filled my field of vision.
Having a strong feeling that I was driving an open inflatable boat rather than a cabin one, mainly due to the design of the console and the roof of the cabin, which is slightly lower than the upper surface of the tubes, I let Verado 350s travel us effortlessly at 3300 rpm for quite a time. It was so enjoyable that we did not realize that we had covered more than 10 nautical miles very quickly.

After a while I began to turn the steering wheel tightly to the right and to the left in order to awaken a bit from the extremely enjoyable and relaxing magic of the moments.
I was impressed for once more by the amazing flexibility that the Rib was showing despite our low speed, sliding very easily until the tubes were limiting our truly impressive inclinations.,br/>Everything indicated that the Rib was responding quite imminently and precisely to the operator's handlings, enabling us to easily maintain the right side angle of the waterline with the water, thus achieving high levels of damping even when driving aggressively into the waves.

Dragging down the controls, Seafighter 36 C insisted on maintaining its magnificent riding angle across the whole rpm range indicating to me that I had in my hands a very well-balanced Rib that needed just a little of the trim use so as to travel with the ideal ride attitude. Definitely the more experienced ones know very well that ideal cruising angle means optimal performance in terms of economy, speed and of course handling and ride quality. In other words, the hull runs faster or the great speed of the hull requires less fuel due to reduced drag and, of course, obeys directly the driver's handling.
The engines’ propshafts were turning two 4-blade Revolution 14 5/8" x 21" propellers which were proving their excellent design features and allowed them never to lose their grip even when we were trimming them too much.

With 300 litters of fuel and two people on board, we were running with 27 knots at 3500 rpm, consuming 2.6 litters per nautical mile. Maintaining that velocity we can cover many miles quickly, economically and enjoyably, having the engines working seamlessly.
At 4000 rpm, we were travelling at a speed of 34 knots, with the fuel consumption being constantly at 2.6 litters per nautical mile. That is an excellent cruising speed where the vented steps seem to reach their maximum efficiency at these rpm. This is shown by the 7 knots more that we got from 3500 to 4000 rpm and the fact that fuel consumption remained the same.
The 2.6 litter per mile of fuel consumption was also the lower one we recorded with the specific loads.

We continued to raise the rpm, and when the tachometer was showing 4500, we were travelling with 39 knots burning 3 litters per nautical mile, while at 5000 rpm our speed was 44 knots with a fuel consumption of 3.4 litters per mile.
With 4’ seas offshore during our sea trial, having the waves coming directly on our bow we did not try to trim the engines to the maximum, and so we hit 55 knots of top speed at 6000 rpm.

You can see our analytical measurements in the following table:

However, we have been given the opportunity to evaluate both the excellent ride capabilities of the hull and its extremely robust construction.
The tremendous flexibility of the Seafighter 36 C combined with the fact that I could easily adapt its ride attitude to the corresponding sea conditions gave me the enormous advantage of making the ride as smooth as possible by scrambling the crests of the waves at high speeds.
The above, coupled with the great sense of safety that the Rib inspires without even asking for a lot of fuel, make it able to travel to distant destinations with great comfort.

On our return the sea had been absolutely glassy and so we were able to trim excessively the engines out until the propellers run very close to the surface of the sea.
With 100 litters less fuel now, we managed to record 58.7 knots of top speed at 6200 rpm, a speed that is definitely excellent for the particular mega-Rib.
Another impressive thing was also its acceleration, since Seafighter had reached 30 knots in 9.5 seconds, while the planning speed was less than 3 seconds, with a particularly indiscernible moment in which the hull was passing from displacement to planning mode.

If we take a closer look at the table of measurements, we will notice the very low slip numbers after 4000 rpm, which is indicative of the very good set-up of this particular Rib-engines-props combination.
We never forget that the slip percentage always shows how a set-up is working!

The props’ slippage of 12% that recorded at 6000 rpm, a very high percentage for Revolution propellers, was due to the increased gearcases’ drag because the sea conditions did not allow us to trim out the engines as much as we would like. On the return, however, when we trimmed the propellers higher, their slip reduced to 4%, which is quite normal for the Revolution props, and so we recorded the great top speed of 58.7 knots.

...keep Ribbing!
