AVILA

The AVILA Story

Founded in 1967, the AVILA shipyard has recently celebrated its 50th anniversary.  Specialising in the design and production of high performance Rigid Hulled Inflatable Boats (RHIBs), AVILA established itself as a leading manufacturer of Military, Commercial and Search & Rescue craft.

More recently, AVILA has used the experience gained in this sector to produce incredible recreational RHIBs for the discerning leisure user.

 

The AVILA ethos is intelligence in design, from the hull to the seating, every aspect of an AVILA RHIB is built for purpose, performance and functionality.  AVILA offers a wide range of boats, ranging from 5 to 9m, across six exclusive lines: Tuono, Velociraptor, Pro, Grifo, Black Mamba & Alien Shadow.

 

Although they have shared design and build technology, each AVILA class is characterised by unique features and specification for a precise role.  From family leisure boats to superyacht tenders and world record beating endurance RHIBs.  There is an AVILA RHIB that will be perfectly suited to you.

CONSTRUCTION

The Rigid Hulled Inflatable Boat revolutionised small power boat designed in the 1960s.  The original hulls however were crudely constructed and the early RHIBs were only 4-5 m in length.  The RHIB’s inflatable collar delivers unparalleled buoyancy and stability but it does not offer any structural rigidity to the hull.  On a conventional hull the hard freeboard increases the boat’s longitudinal strength.  On a RHIB it is crucial that the rigid part of the hull is well constructed to give the boat its strength.  A solid boat is a safe boat.  With years of experience, building commercial and military grade RHIBs, AVILA hulls are virtually indestructible. Below is an example of how an AVILA hull is constructed; from our 5 metre RHIBs to our 9 metre Touno.

The longitudinal and transverse frames of an AVILA RHIB are made from the best Okoumé marine ply.  The Okoumé core is encapsulated in resin and therefore rot proof.  This construction method meets the highest military standards and the lightweight marine ply (430 kg/m3) keeps the overall mass at a minimum.

An AVILA transom has a composite construction; with an Okoumé core, chop strand mat and multi-axial cloth.  The transom design, dimensions and construction will support engines with twice the power of similar sized Rigid Hull Inflatable Boats.

This is the real soul of an AVILA; the frame at the core of all our RHIBs…

For over fifty years AVILA strives to continuously innovate and improve its designs.  This development has led to an exclusive new concept… The AVILA Self-Supporting Hull.

The RHIB’s inflatable collar delivers unparalleled buoyancy and stability but it does not offer any structural rigidity to the hull.  On a conventional hull the hard freeboard increases the boat’s longitudinal strength.  Traditionally, RHIB designers used a structural deck to compensate for the decrease in the size of the rigid element of the hull.

 

An AVILA hull takes its strength from its longitudinal and transverse frames.  The deck is not a structural part of the hull and can be removed and easily replaced, thus allowing a virtually infinite possibility of fittings and alternative layouts.  In fact, everything above the hull can be removed or changed without affecting the structural integrity of the boat.

 

Hull rigidity is key to a RHIB's performance; better performance means higher speed and lower consumption.  AVILA’s unique hull designs also offer comfort and are easier and more pleasurable to drive.

THE AVILA SELF-SUPPORTING HULL

The AVILA Self-Supporting Hull has considerable advantages; it improves safety and performance but also allows unlimited options for customisation.  As the hull remains the same, converting an AVILA for a specific role can be a cost-effective solution rather than designing a new boat.

At Avila we can create almost any feature, required for your specific requirements. With our Self-Supporting Hull it is cost effective to redesign everything from the deck up without any expensive structural changes to the boat.  This enables you to remodel your existing boat rather than having to purchase a new one.

It is also possible to request a foam filled hull and because of the design of the AVILA Self-Supporting Hull it is even possible to do this retrospectively.  A foam filled hull adds additional safety; making the boat virtually unsinkable.

As all the strength is in the hull, it is possible to significantly lighten the deck of the boat. Which results in a rigid hull inflatable boat with a lower centre of gravity.  This helps further increase the stability.  A non-structural deck also allows easy access to the underfloor systems, making any maintenance or installation of new accessories or fittings really simple.

We use only Vinylester resin in order to optimise the mechanical efficiency of multi-axial and unidirectional fabrics, as well as carbon fibre.  Thanks to the variable-core sandwich technology applied across the entire construction of the boat; we are able to increase strength and reduce weight.  We believe Avila RHIBs are the safest, fastest and most efficient RHIB hulls on the market.

DEEP ‘V’ HULL

The Deep ‘V’ Hull is the trademark of a professional RHIB, guarantying safety and comfort for offshore operations.  A true deep ‘V’ hull has a high dead rise, greater than 21°.  Dead rise is the angle of the hull from the horizontal at any given point, but the transom dead rise is the key.  After all, on a planing hull, most of the time, only the aft section of the hull is actually in the water.

The greater the stern height, the larger the waves that the boat can face while maintaining stability.  When a boat is stable it can maintain higher speeds.  At speed the Tuono hull is also incredibly efficient, with the larger models featuring ‘multi stepped hull’ technology.  These transverse steps in the hull, are intended to reduce the amount of hull surface in contact with the water.

 

BOW STEM ANGLE

 

Whilst the transom is key when the boat is planing or driving into a head sea, the shape of the bow is crucial going ‘down sea’.  The angle and shape of the stem will determine how the bow cuts though the waves.  A fuller curved bow can have a ‘rudder effect’, where the boat starts to steer from the bow.  In the worst-case scenario, the hull can turn on the wave and dig in causing the boat to capsize.

Sleek Avila Bow

 

The Tuono hull has a sleek, swept back stem with a greater angle.  This reduces the surface area of the hull in the wave and therefore minimises the possibility of ‘rudder effect’.

THE SELF-SUPPORTING HULL IN PRACTICE

 

To illustrate the concept of the self-supporting hull and its versatility, the photos below show the same boat with two completely different set ups.  The top picture shows the Tuono 9 in a sporty leisure configuration.  The same boat was subsequently transformed into the record breaking endurance RHIB in the bottom photo.  With this boat Avila will try to break the record on the Monte Carlo-Venice route for boats up to 9 meters.


The engines were upgraded from twin 175 HP to twin 200 HP but the hull of the boat is exactly the same.  Utilising the benefit of the self-supporting hull, all of the deck furniture has been stripped down to make way for the enormous fuel tanks; from 350 to a whopping 2230 litres.  The console is built on a lightweight aluminium frame as are the seats for the crew and the mast for the equipment.
