Wing Decks

WING DECKS


1; 
 
Base Panel.
Weight:  20 Kg

This panel has no Gelcoat for adhesion to Hull Deck. Construction is 2 layers of 450g Uni @ 0 & 90 Then 12mm GS Foam followed by 2 layers of 450g Uni @ 0 & 90 .  10 Kg of resin used.

2:   Outer Side Panel.
Weight:  26 Kg.

First external Hull Panel
Gelcoat outer skin with 3 layers of 450g Uni @ 0 & +/- 45, then 20mm GS Foam with 2 layers of 450g Uni @ 0 & 90. 12 Kg of resin used.
Starboard side panel shown.

3:   Inner Side Panel.
Weight:   14 Kg

This panel uses the same construction technique as the outer panel.
Port side panel shown. 7 Kg of resin used.

4:  Deck.
Weight:   12 Kg

The deck is the same construction as the sides. Note the conduit for the trampoline Plexised & glassed onto the edge radius with 450 gm bi-axial prior to assembly of the wing deck proper. A hatch is yet to be cut into this panel. The rebate is for attachment of the step section.

Weight;   12 Kg
 
The panel was made with normal techniques  then removed from the table while the resin was still flexible ( 3 Hrs). It was then cut to shape with 27mm by 8mm trenches machined in the underside on the CNC machine. It was then folded into shape, creating smooth external curved bends. Then the angles were glassed on the inside.

ASSEMBLED WING DECK

This view shows the assembled wing decks with the molded bow dry fitted and the trampoline conduit fared ready for painting.


This mold assembly was made using measurements sent to the CNC machine for the cutting of the templates to achieve the correct deck side slopes and bow angle.
 

 


FINISHED WING DECKS
Below are photos of the wing decks fully finished ready for attachment to the main hulls.

 
 

POINTS OF INTEREST.
Cleats and stanchion post supports are cut from lengths of high density fibreglass rod called "Rock Bolts". A form of reinforcing bar used in harsh environments, e.g. marine concrete pylons. These rods have a rough texture finish with a diameter of 19mm with 4 longitudinal ribs making total diameter of about 21.5 mm. The stanchion supports extend above deck 300 mm & below deck 200 mm. A sleeve of thin walled heat shrink over the rod makes a perfect fit inside 25 mm * 1.6 mm 316 stainless posts. A grub screw at the base of the post makes for a very strong and very neat 800 mm high safety rail system
The forward mooring cleat is made using rock bolts with 450 gram uni glass strips laid over the cross bar and wrapped around the vertical posts which are then glassed under the deck.
The aft cleats are also lifting cleats for the vessel. There will be 2 more located at the Aft Beam position. These cleats are similar in design to the bow cleat. The 2 posts extend 200 mm below the wing deck to be glassed into the main hull for lifting security. These cleats are wrapped using 6 layers per post of 15 strand 220 gram uni directional Kevlar laid over the cross bar then spiral wrapped up to 600 mm down each post. Tests have shown the breaking strain per strain of 1 strand of this Kevlar is 20 kg, giving the cleat a lifting capability of approximately 7 metric tonnes, which is more than double the required load.
The step courtesy lights are low wattage 12 volt blue LED's.
The hull colour is CLARET. The photo in the container is probably a closer representation than the photos taken in sunlight. You have to love the reflections from the 2 pack finish.
The fair lead on the bow is for the anchor bridle when needed.
Deck Tread will be added after assembly is complete.

Final weight for each wing deck is   132 Kgs                         Centre of balance is  station 1 plus 780 mm.
