Building technology

 

The boat is produced using epoxy resin sandwich and glass fibre, with mahogany lamellar and top lamellar core. The building process consists of several stages, let's see them by outlining the main points:

 

1st stage:

lamellar or top lamellar folding; it is molded on special steel templates, cut through the laser, to allow a precise assemblage and a perfect symmetry of the hull, that is equal or greater when compared with the best boat produced through moulds;

2nd stage:

structural gluing and double inside taping of the core, in order to produce a monolithic hull, as if it was shaped in one only piece;

3rd stage:

stiffening and reinforcement through four longitudinal stringers that start from the bow and integrate with the bracket; these reinforcements are oversized both in the thickness and in the height and are glued to the hull through epoxy resin and taped with glass fibre and carbon fibre to increase its rigidity; then there's the laying of the transversal reinforcements obtained through structural bulkhead made of okoumè multilayer to bear weights, with 40 mm thickness, bound to the to the hull through the same procedures as the stringers. Covering of the hull's inner parts with epoxy and glass fibre. At this stage, the hull has an exceptional solidity but with a great control of weights;

4th stage:

we go on with the setting of the installations and of the tanks, paying attention to the position of pipes' cables and to the perfect fixing of the whole equipment and of the hardware components, in order to allow easliy future operations;

5th stage:

structural gluing through epoxy for floor-boards, for the reinforcements of bulwarks, and of the supporting bulwarks, in order to obtain a double hull, improve the resistance and guarantee the unsinkability;

6th stage:

we upset the hull, do a double taping of the core in the junctions and cover it with epoxy and glass fibre like we did in the inner parts.

 

During and after these stages, we obviously sandpaper, point and totally protect the most hidden parts, to obtain an inner part that is perfectly smooth and well done also in the peaks, in the bilges and in the most hidden parts, that are covered with epoxy gel-coat. The result of these stages is a resistant and light boat, made stronger through the powerful ring structure that absorbs the shocks coming from everywere and guarantees a greater torsional stiffness; to conclude, the boat's solidity can be compared with any other existing total fibreglass boat and the link weight/resistance can be compared with aluminum technologies and with the infusion sandwich technologies made of hi-tech materials. The geometry of the bottom, that is variable with two twin-hull boats with a high deadrise already in the stern sections (23°), is very marked in the bow (55°) and it has already been tested and optimized to guarantee the best navigation with short and steep waves, typical of the Mediterranean. Furthermore, the double hull and the marked loom guarantee the anchorage high stability and absence of spattering during the navigation.

 

The hull is also compartmentalized under the floor-boards, so every space among the structural bulkheads is an autonomous volume, with a bilge pump, in order to have a further safety guarantee in case of difficult sea conditions and in case of meeting with a big breaker. There is a box ballast of around 400 liters (water ballast), fillable with sea water, through the opening of a manual rolling shutter or through electromagnetic valve controlled from the console, that allows to advance the barycentre, to increase the transversal and longitudinal stability and to consequently improve the impact on waves in case of difficult meteorological conditions, or to give the anchorage more stability. This box can be emptied shortly through a proper motor-driven pump.

 

We work carefully, without saving time and materials, so we guarantee an excellent quality in the finishing touches, in the plant engineering, in the facility of maintenance and in the assemblage of installations, details and accessorieses, and we guarantee the production of a unique quality boat, with no compromise.

 

The hull can be emptied also when still, it is unsinkable and optimized to face difficoult situations during the navigation.

 

Akes 27 is suitable for different uses; it's possible to customize the deck layout on the base of uses or desires, the cockpit can be equipped as fisherman for game fishing, underwater activities, pure recreation and for any other specific function.

 

With the maximum engine power of two 200 horsepower - outboard , Akes 27 will sale mightly and safely to over 50 (real) knots, leaving behind it many boats of similar or lower dimensions and with higher horsepower.

 

The building materials

 

Epoxy resin and inactive micronized charges.

 

The epoxy resin is the only resin that is used because it has better characteristics than polyester and vinylester resins normally used for boats. In fact it has a better water permeability and there's nearly no shrinkage; its chemical and mechanical characteristics are very high. It is immune to osmosis and because of its molecular bonds it lenghtens more than 6% before breaking; its characteristics can be modified and improved through the addition of inactive micronized charges, both to increase its strenght in structural glueings, and to use it as filler with low specific gravity and high resistance to scars, physical and chemical attacks. The charges we use most are glass and phenolic microspheres, silica, graphite, glass microfibres, additives to the aluminum powder.

 

Glass and carbon fibres and tapes.

 

We use biaxial glass tapes and materials turned to 45°, in different grams, to work all the fibres and to make up for the core's anisotropy, and we use unidirectional carbon tapes to considerably increase the stiffening of stringers.

 

The multilayer materials.

 

For the core of the hull we use only mahogany superlamellar and lamellar with RINA approval, both for the better characteristics of bending resistance and for the resistance to the submarine use; for bulkheads and some inner details we also use okoumè approved multilayer panels, as they have good resistance and lower specific gravity. On request we can provide you with floor-boards covered with multilayer teak, or with teak bloom.
