Slot Strip
Slot Strip is a specially formulated laminate of Polyester film and
Dacron sailcloth.
It has very special characteristics of rigidity, flexibility and tear
resistance making it a perfect film to cover your centreboard/daggerboard
slot to keep water out but allow your centreboard/daggerboard to pass
through it.
Slot Strip can also be used as transom flaps on Racing Dinghies and
Rudder/keel fairings on Yachts.
Slot Strip is available in either 30m rolls in a box with instructions
or in a short length in a blister pack with the Contact adhesive ready
to fit. The rolls are in 32mm, 36mm, 46mm, 50mm, 75mm and 150mm widths.
The Blister packs come in 46mm x 3m, 50mm x 2m. 50mm x 3m and 75mm x 2m.
When fitting slot strip you will need to decide whether to fit 1
complete piece covering the whole slot and cut a centre slit down the
middle for the centreboard/daggerboard to emerge, or whether you want 2
separate strips (1 on either side) that overlap by about 1cm.
Most boat builder will fit the Slot Strip from new with epoxy or
Sikoflex compounds. Hawk Marine Products recommend that for DIY
replacements you use a contact adhesive. The blister packs all come with
a contact adhesive included.
Slot Strip – Fitting Instructions
1. Firstly remove all traces of the old gasket and associated
glue. This is best achieved using a
sharp 1” chisel.
2. Place masking tape or similar around the centreboard slot
to ensure there is no glue spillage
on the hull of your boat.
3. Ensure the surface of the hull that is to be glued is dry
and free from dust.
4. Lay the slot strip in place and draw the shape required to
fill the centreboard recess.
Shinny side to the outside.
5. Cut out the shape on the Slotstrip and ensure it is a good
fit.
6. Mark the slot down the middle of the Slotstrip. It needs
to be about 25mm longer than
required at both ends.
7. Cut the slot in the Slotstrip with a sharp knife.
8. Lay the Slotstrip upside down on a board and pin it down
at each end with drawing pins.
9. Apply a coat of contact adhesive to the boat and to the
slot strip making sure the corners
and edges are well coated.
10. Wait til both surfaces are touch dry. Un-pin the
Slotstrip and attach one end to the boat.
11. Apply plenty of pressure and work slowly to the other end
and push the Slotstrip firmly into place.
12. When you are happy it is properly in place, go over it
with a small roller ensuring there
is good contact
over the whole area.
13. Apply tape to the edges to ensure it stays down firmly
while it dries.
14. Leave for 12 hours to cure before removing the tape.
If using 2 separate strips (one on either side) omit instructions 6 and
7 above.
