MAR.CO R-Evolution X36 – 2 x 400 V10 Mercs
Although I have been many times behind the steering wheel of all Mar.co models, I have to admit that every time I am impressed both by the quality of construction and finish and by the great comfort of movements they offer on deck, having a great comparative advantage with Ribs of corresponding length in each category.
The R-Evolution X36, born from the R-Evolution 35 to which a large bracket was added resulting in a huge increase on the free surface of the swimming platform, can boast of having all the above elements while being able to travel safely and comfortably to distant destinations.
Although we have tested her several times before, this time we were invited to test her with Mercury's new V10 400hp engines at the 63rd Genoa Boat Show. Our impressions were excellent as the boat performed very well, while the feeling we got in terms of ride quality was excellent which led us to the conclusion that this particular set-up is ideal and we definitely recommend it without any hesitation.
On deck
The R-Evolution X36 is extremely generous in both bow and stern spaces, combining ergonomics and functionality with quality of life at sea. It has a large sundeck in the bow, a separate bathroom in the console, a huge living room in the stern which with the help of the electro-hydraulic table can easily be converted into a large dining room or a spacious sundeck and, of course, a very large surface on the bathroom platform for our seafood activities, that even the boats with inboard-outboard engines would envy.
The instrument panel is excellently finished and has ample space for even the largest navigational devices, while the electrical switches and overall equipment are characterized by their high quality, demonstrating the attention given by the yard to even the last detail.
The polyester construction that carries the outdoor kitchen is very nicely designed and also excellently finished, while the hard top stands out at first glance for its elegance while effectively protecting the occupants from the sun and rain.
At sea
On the bracket of our seatrial’s R-Evolution X36, the two powerful V10 400hp Mercury outboards were mounted, which with a maximum rpm range of 5800 - 6400 and a gear ratio of 2.08:1 were turning the new 18΄΄x 21΄΄ Revolution X 4-blade propellers.
With relatively good weather conditions, 400 liters of fuel, 3 people crew and all the equipment of the boat, we set out in the waters of Genoa to record the performance of this new set-up.
Our impressions were excellent as we once again enjoyed the wonderful and perfectly smooth and quiet operation of Mercury's V10 engines, even when we pushed them to their limits reaching their maximum rpm.
Accelerations were explosive throughout the whole rpm range, with the R-Evolution X36 starting almost flat with no tendency to rise her bow, while its maneuverability was remarkable, making us believe we were driving a much smaller boat.
You can see the detailed measurements in the table below:
The Rib was standing on plane at just 2000 rpm maintaining the extremely low speed of 11 knots, which allows us to travel on plane mode in bad weather conditions resulting in an increase of our range.
The planning time was under 4 seconds, while the boat accelerated to 30 knots in 6 seconds and reached 40 knots in 10 seconds.
At 3000 rpm we were cruising at 20 knots consuming 2.6 liters per nautical mile, recording the most economical cruising speed.
At 3500 rpm we were running at 24 knots burning 2.95 liters per mile, while at 4000 rpm we were travelling at 29 knots with the engines demanding 3 liters per mile.
At 4500 rpm our speed was 34 knots with a fuel consumption of 3.4 liters per mile, while at 5000 rpm we were running at 38 knots burning 4.2 liters per nautical mile.
At wide open throttle, the engines reached their maximum rev limit and the R-Evolution X36 recorded a top speed of 49.5 knots.
Taking a good look at our table of records, we note once again the extremely low slip numbers that the new Revolution X propellers give us, even in the low rpm range where we usually see the highest slip rates. These figures are very important if we consider that at the cruising speeds we usual travel, we can achieve the lowest possible fuel consumption with a direct result of increasing our autonomy.
The design features of the new Revolution X propellers improve acceleration and fast hole shot especially when carrying heavy loads, provide excellent stern lift and "bite" great in the water, but I think that for our use in inflatable boats it would be better to be reduced by 1 inch in diameter so as to be able to switch into longer pitch with virtually no impact at low rpm.
