NJ 700 SeaFish, having maximum width of 3.24 meters and internal 1.86 meters in its stern, dimensions even bigger than those of many 9-meters ribs, clearly holds the title of the 7-meter rigid inflatable boat with the largest width ever built.
The NJ 700 SeaFish rib is the twin sister of the NJ 700 XL one, and as its name implies, it is an excellent fishing machine with top-level equipment for any kind of fishing.
Although designed for fishing enthusiasts, it can also be used as a pleasure rigid inflatable boat for general use, since it retains the typical design of an open-rib forward its helmseat.
One of the most important characteristics of NJ 700 SeaFish is that it has been built on an all-new and highly seaworthy hull which borrows a lot of features from our well-known King 670 and Prince 21.
The hull, with a sharp bow entry of 45-degrees and 22-degrees of deadrise at its transom where a few centimetres pad is formed, produces the lift that is necessary for immediate planning, faster acceleration and high stability at high speeds.
The relatively low deadrise at the transom combined with the configuration of the flat pad, which provides a wider surface on which the hull runs, generate more lift as the rib accelerates, thus reducing the wet surfaces and the drag, and therefore the need for high horsepower.
This is why NJ 700 SeaFish can also perform very well even with 200hp on its transom.
The major benefit of NJ 700 SeaFish is its wide and open cockpit that provides plenty of room making it great for fishing, while the aft deck is self-draining giving us the ability to clean it very easily.
Taking a careful look at the area behind the driver's seat, we find out that NJ 700 SeaFish has nothing to jealous from a typical fishing boat.
On the port and the starboard gunwale we can see six fishing rod holders while another five ones are located on the back gunwale, whereas there are two glass-holders that will hold the drinks during fishing.
On the starboard gunwale, there is also a rubber cap under which there is a freshwater shower for washing off the blood and dirt from the fish we have caught, as well as for rinsing off the salt from our usually expensive fishing equipment.
The easiest way to board NJ 700 SeaFish from the dock is at its back, where there is plenty of space on the swimming platform, while the ladder is very well nestled in its own space, under a hatch, without obstructing our entry or exit.
A 31 centimetres opening to the port, leads from the swimming platform to the cockpit while it is ideal for transferring a big caught fish to the aft deck.
The console is centrally located leaving large passageways to its port and starboard for comfortable fore and aft movement, measuring 35 centimetres of width.
In its front part there is a smartly designed reclining seat, behind of which there is a large hatch that gives access to the interior of the console. The windscreen is particularly tall, providing the necessary protection against the wind and spray while ensuring excellent visibility to the bow when driving in a leading position.
The helm’s panel is well-organised, providing enough room even for two large multi-screen displays that serve the ultimate fishing enthusiasts.
The steering wheel is located to the port of the console while to the starboard we see the ignition key, the engine control and the rocker switches of the electrical equipment of the rib, all easily accessed and close to our right hand while driving.
Below the steering wheel there is still a large hatch leading into the interior of the console, while lower there is a molded-in footrest which is covered with teak and has the proper height and inclination angle for resting the legs.
The rib is also equipped with a stainless T-top, which is supported on the deck and the side surfaces of the console. It is certain that it will be particularly appreciated since, apart from the necessary shade it offers, it also provides extra space for the installation of antennas, lights, GPS receivers while it can accommodate even four fishing rod holders.
The double helm seat is build on a fiberglass construction and surrounded by a stainless steel rail that is suitable as a long handrail too, while it can also be used as a base for four additional rod holders, which finally reach 19 in total number.
Behind the driving seat, a large livewell is formed that drains overboard. It automatically fills by pumping fresh sea water that is very essential to keep the baits or fish alive for a prolonged period of time, while it can also be used as a great cooler when don’t go fishing.
On its side surfaces, we can see the very useful small drawers for storing consumables such as hooks, fishing lines and every kind of the proper gear.
As it can be seen in the below photo, the area in front of the console follows the classic configuration of a typical pleasure open-rib. The V-shaped bow lounge consists of three independent lockers, among of which, the table is placed creating a large gathering area or a proper extension with which a spacious sundeck is formed.
NJ 700 SeaFish of our test was fitted with the previous generation supercharged 6-cylinder 250hp Verado which, with the larger and stronger gears of its heavy duty gearcase and 1.85:1 gear ratio, was turning a 3-blade 16"x19" ECO Enertia propeller.
With 180 litters of fuel and 2 people on board, the 2.6-litter outboard engine provided the necessary torque and the 16-inches of diameter ECO Enertia propeller effortlessly popped the rib immediately up onto the plane at 2500 rpm in a speed just of 11 knots.
At 3000 rpm our speed was 18 knots, consuming 1.36 litters per nautical mile, while at 3500 rpm the speed climbed to 27 knots and the fuel consumption decreased to 1.31 litters per nautical mile. This was also the most economical cruising speed giving us a range of 137 nautical miles when our tank is filled with180 litters of fuel.
At 4000 rpm we were running with 31 knots burning 1.41 litters per nautical mile, while at 4500 rpm our speed reached 36 knots with a fuel consumption of 1.66 litters per mile.
Pushing the Verado engine to 6000 rpm, the NJ 700 SeaFish’s hull was running almost all out of the water, and only its last sections were keeping its contact with the sea surface, reaching 47 knots.
You will find our detailed measurements in the following table:
NJ 700 SeaFish of our test consists an excellent combination of very good ride quality, high cruising speed and fuel economy.
It can carry us to distant fishing grounds but also turn us back to our base quickly and safely in the case of a sudden worsening of the weather conditions, since it can achieve great cruising speed even in rough seas where the sharp forward section of its hull undertakes to cut the big waves effectively, providing an excellent smooth ride.
The only thing we have to do in our test’s set-up is to choose a shorter ECO Enertia propeller, allowing thus our engine to come closer to its maximum rpm while the rib will be hold on plane at lower rpm and, of course, we will see much stronger acceleration.
If we take a closer look at the above table, we can see that the slip values are of great interest. From 4000 to 5000 rpm, the slip numbers are excellent, while at 5500 rpm they reach their lowest value, which is only 3.2%. This is a great number and shows us clearly why ECO Enertia achieves such a good performance in terms of fuel consumption and cruising speed.
We will also see that from 5500 to 6000 rpm we got only 2 knots more, meaning that we may had probably trimmed the engine excessively resulting in the ventilation of the propeller, and maybe the 6000 rpm we saw did not correspond in reality.
It is possible, however that the large diameter of ECO Enertia propeller starts to work negatively because at 45 knots and after, the water is no longer the same; it’s like changing completely its composition…
