Construction |
|
This rib
is constructed with a medium to deep “V” warped hull,
from a corrosion resistant GRP ply epoxy composite.
The hull can be to any regulation, regarding strength
and impact resistance. Can be rendered unsinkable, by
the addition of foam in the hull. Anti-slip glass cloth
/ epoxy 12mm. plywood deck.
The tubes of the rib are constructed from Polyurethane
, either black or orange
Hypalon
850 gm.). black,
orange or grey
PVC.1100DTex..in
almost any colour,
The tubes (Collar) have 4 or (6)
separate chambers, each with its own independent valve
in an inner tube. The tubes are 480mm in diameter.
Rope holders for
lifelines. and 4 PVC fender
/ rubbing strake, 100 or
200mm. wide
Repair kit for inflatable tube (incl. patches for tube
and inner tube material)
Please note we cannot ship Tube glue by
air freight, but you can get it
locally. |

Complete parts kit of plywood and GRP composite hull plates. |
 OR Templates
are available, for
you cut out parts, to
keep costs down.
 Two
hull plates are supplied, they are joined together, and sealed
along the keel line, with a special self adhesive tape,(
which can be removed later).
The
hull plates are 7mm marine quality plywood, bonded to a 2mm,
GRP plate, which has a gel coat on the outside.
The mirror finish is better than anything out of a mould.
The
GRP/ply composite plate needs additional support inside
the hull. This support is either,
glass. with polyester resin, epoxy and woven glass, or 6mm
plywood, glued in and then epoxy coated.
We
can supply the 2mm. thick GRP sheet on a roll, together with
instructions, how to make the
composite hull plates.
This saves money on transportation cost
.The GRP composite hull is opened out, like a book, and the
transom and 2 bulkheads are glued in place with epoxy.
 12
mm. plywood strips are glued in place with epoxy,
around the hull perimeter, and across the two bulkheads.
The hull can be partially filled with styrene foam,
for additional buoyancy.
 Strengthening
support timbers are glued inside the hull, both
to strengthen it, and to support
the external running strakes, and to carry the stringers, see
below.
All
joints are
strengthened and sealed with epoxy paste.
 2
types of stringers.
Installed before the deck is fitted
The
hull can be further strengthened by coating the inside with
resin and chopped strand glass matt,
to
the thickness you require.
Glass cloth and epoxy resin can also be used as an alternative.
This is quicker, but the materials
are
more expensive.
Being on the inside of the hull, means no great finesse is
required. And the hull can be laid flat.
this
makes it simple to lay the RP / Epoxy strengthening laminate.
