TEAM fgi has been designed as a true ocean going sports boat that will have the appeal for club racing or a rugged Hobart racer.  The boat features a fine hull form for speed and low form drag, but with built-in pod wings for water ballast, thus establishing a high righting lever for crew weight.

 

Hull and Layout Perspectives

Careful attention has been given to building materials to achieve a suitably low centre of gravity to meet the design parameters.  This is where our team of sponsors from Fiber Glass International has become invaluable to assist the design process,

A vast amount of experience has gone into the selection of deck hardware, spas, and sail wardrobe for this type of yacht, which was originally conceived around the Melbourne / Osaka Double Handed Yacht Race.  

With the assistance from our sponsors fgi, Diab Australia / Klegecell and Torayca, she will be constructed of Epoxy R300 resins and an engineered combination of PVC foams, stitched and directional 'E' glass and carbon fibre skins, to give a strong but light weight yacht.

THE CONSTRUCTION PROCESS

A mould was fabricated for this Sayer design.

Hull and mould fabrication                             

The hull station frames were cut by a CAD-CAM router machine loaded directly from the Maxsurf software to achieve the most accurate hull mould possible without 5-axis tooling.  

Longitudinal stringers were formed over the stations.  Flexible ply was then laid across  the pine strips and stapled into position. A layer of fgi fibre glass was fixed to the ply, prior to fairing, sanding and painting.

Keel and mast compression girder framework

The keel and mast compression girder frame work has been cut into the hull mould to ensure a neat and professional finish internally.

Deck mould fabrication

In contrast to the hull, the deck will be fabricated from a female mould.  Similarly to the hull, the station frames for the deck mould have been cut to form the designed shape. Although accurate, this mould will be left void of contours and impressions so that future yachts may be tailor made for the customers' own thoughts on deck layout.

Fiberglass process

The process begins ensuring an accurate forming of the bow section to ensure strong chainplate adhesion in a later process

Placing carbon fibre on the bow section

Keel section re-inforced

Once the initial primary inner laminate has cured, extra uni-directional fabrics and stitched fabrics are added to reinforce the keel-mast area for greater strength. Large de-bulking of excess resin is required in these difficult areas by vacuum bagging

Klegecell foam specialists

Klegecell specialises in different types and grades of foam for the required areas on the modern yacht. Consult your rep for the best results. "Team fgi" has her keel and slamming areas portioned in a higher density core for superior 'core-shear' properties.

Vacuum bagging hull

The outer skin has been hand laid in position and the whole laminate is vacuum bagged to the foam for a superior bond and weight to resin ratio for the final skin. The new Fiberglass International resins are ideal to match the temperature with the open time for ease of lay-up without getting caught out and rushing the job. The wet lay-up was applied in the cooling air conditioned enclosure and then the temperature was then elevated for the cure.

Bleeder cloth

Checking the bag for any air holes to ensure a good vacuum.Note the bleeder cloth which allows drainage of excess resin to be removed and also to allow a thorough bleed of air which can travel from remote areas to the suction point.

Torture board

Nothing can compare with the accuracy of the long torture board to give a truly fair curve on the hull surfaces. Hired hands usually run for the hills when this apparatus hits the shop floor as it entails hard work for a few days to bring the hull to its final coat.

Longboard sanding

Releasing hull from the mold

After some gentle coaxing around the edges and a few blow holes in the bottom of the hull, the hull is released from the mold.

Raising the completed hull off the mold

The turning process begins

The hull is wheeled outside to allow room to turn the hull over

A single point lift is all that is needed for the hull shell with keelson and floor girders to be turned over

Turning over

The completed turn and she is ready to be wheeled back into her controlled tent environment for the fitting of all the ready made furniture and bulkheads from the vacuum table

Nestled in the cradle to be wheeled back inside.

Internal layout

The internals are fixed to the hull shell

All bulkheads and girders are glass and carbon taped into the hull to make a strong light weight structure
