The building process
is described on three pages:
- Making the
foils, hull, and A-frame (this page)
- Making the
sail (click here)
- Finishing
touches (click here)

1 Making the foils, hull, spar, and A-frame |
December 2005
 |
construction of
foils - centreboard and rudder |
 |
foam core,
carbon fibre spar and edges, epoxy/glassfibre covering |
|

 |
 |
construction of
centreboard box from marine ply and expanded polystyrene |
|

 |
January 2006
 |
began making jig
to support assembly and shaping of craft |
|
 |
 |
panels added to provide surface on which
to place foam core |
|
 |
 |
completed central stringer, with rudder
mounts, centreboard box, vertical tube for potential use of
windsurfing rig, and forward-facing tube at front end for
optional bowsprit |
|
 |
February 2006
 |
core built up from 5cm-thick
panels of expanded polystyrene |
 |
initial rough-shaping of core |
|


 |
 |
final shaping of upper deck surface |
 |
layers of glass fibre cloth laid dry over
core - 3 layers in main deck area, 2 elsewhere |
|
 |
March 2006
 |
epoxy resin added to wet the cloth layers |
|

 |
 |
side-tubes added |
|

 |
 |
additional coat of epoxy |
|
 |
 |
after shaping, 2 layers of glass fibre
cloth applied to under surface and resin added |
|
 |
 |
central ridge built up with foam in front
of and behind the centreboard box |
|
 |
 |
initial shaping of central ridge |
|
 |
 |
foam fillet added between ridge
and under surface |
|
 |
 |
two layers of glass fibre cloth
laid on with resin |
|
 |
April 2006
 |
mast made from curving aluminium
tube 1¼" OD wrapped with layers of carbon fibre tape/epoxy
resin in several different orientations |
|

 |
 |
two reinforcing layers of cloth added to
edge of craft |
|

 |
 |
filler coat applied to lower surface of
craft, not yet sanded |
|
 |
 |
upper ends of A-frame joined, and top
mast bracket added |
|
 |
 |
front bracket for mast made from
stainless steel plate |
|
 |
May 2006
 |
sanding of underside in progress |
|
 |
 |
working out optimal dimensions
for mast and A-frame |
|

 |
 |
fitting front bracket for mast to nose of
craft, lacing with wire around underside of nose tube |
 |
two additional layers of glassfibre/epoxy
resin were then added on top of the bracket feet
|
|


 |
 |
with the A-frame and mast now complete, a
paper template is made for the sail |
