SeaDNA 999 is the first model and best seller that placed Technohull Company into the world elite of high performance rib manufacturers.


Technohull was founded in 2005 by a team of people passionate with the inflatable boat. Since then, the Company expanded significantly its network of worldwide sales by producing crafts of unique quality, design and performance, targeting in the international market of luxury rib.

SeaDNA 999 is a high performance rib with prestigious and luxurious appearance.
Its stunning look and unique aesthetic which are even more highlighted by the totally flat riding and the almost total view of the hull design lines are just some of the plenty enviable characteristics.

The fast hull –«deep-V» with its two ventilated steps, designed by Adam Younger-, the excellent quality, its low fuel consumptions combined with the comfortable living in its very beautiful and elegant spaces constitute a complete compact which can offer only moments of joy and adrenaline high doses to its happy owners.

On the deck

In the deep bow there is a low cabin with 2.20 meter of length which can accommodate two people. Its superstructure marginally exceeds the height of the tubes and fits perfectly the sporty lines of the rib.

On the cabin roof a huge platform is formed that can be coated with teak. In front of the hatch there is a spacious locker for the windlass while the anchor outlet is located under the bow.


Technohull SeaDNA 999 is a rib with huge range of choices in colours, designs, materials, selection of accessories even adopting design solutions. The fact that the space between the bow cabine and the console can be converted into a dinette, depending on the customer's choice by adding a semicircular sofa and a round table, is something indicative.

The design of the ergonomic console allows the comfortable passageway from both sides giving easy access fore ‘n’ aft, while its interior houses the marine toilet. Regarding the helm seats, the owner can choose from a wide range, which always offer good lateral support and efficient holding of the body in all driving positions.

At the stern behind the helmseats there is a four-seater sofa, at the back of which the large sundeck of the rib lays, with a huge storage space inside.

Luxury and performance, ergonomics and style, plenty of space and pure lines, available to the custom’s choice respecting the company's aesthetic, speed and smooth ride are the things that all manufacturers are looking for.
In Technohull, they are doing it extremely well!


At the sea

The new twin Verados 300 hp that was mounted on the small brackets performed excellent due to the overall design of SeaDNA.

The rib comes on plane just at 2600 rpm, at speeds that vary in a range from 15 to 18 knots, depending on the propellers we have matched.

We continued pushing the throttles and we were travelling with more than 30 knots just at 3500 rpm, despite the heavy loads of the rib.

This is an excellent performance that every rib would envy and every pilot would want, especially in long journeys. At these speeds indeed we got the lower fuel consumptions, thus increasing our autonomy.

p>But just above, at 4000 rpm, our speed was approaching 40 knots, keeping the fuel consumption constantly close to 2 litters per nautical mile. It is noteworthy that 40 knots is an absolutely pleasant and normal cruising speed for SeaDNA 999.

Pushing more the throttles until the WOT, the hull responded immediately and it was offering a very sweet and perfectly balance ride.


We were feeling perfectly safe and enjoying the high speed, while the hull was clearly showing that it can run with the same safety even more, balancing very steadily at its aft sections.

You can see our measurements, with the rib heavy loaded, in:
Moving the engine just one hole up or down can have a huge affect on boat’s performance

...keep Ribbing!
