Fenders are made to protect your boat,
even in tough conditions. When deciding on the size
and number of fenders, plan for the unexpected and toughest
weather conditions. Also consider extra fenders in addition
to the "basic need".
Depending on the shape of the hull, weight
of the boat etc, consider a possible mix of cylindrical
and / or spherical fenders to achieve maximum protection.
Please note that the fender guide to the
right can only provide guidance, and that local conditions
are of vital importance. If in doubt, seek professional
advice.

Inflation
Guide
Important!
Do not over-inflate as this will weaken the product
and void the warranty!
Polyform products are designed
to be inflated to 0.15 to 0.20 bar of pressure
at 20 degrees Celsius. For use under tropical
conditions the pressure has to be reduced to 0.05
to 0.06 bar.
When inflating products without
a pressure gauge, fill the fender / buoy until
the walls start to expand and make sure that you
are able to depress the wall at least a quarter
of an inch (approx. 0,65 cm) with light hand pressure,
(for tropical conditions: approx. half an inch
or approx. 1,5 cm). Do not over inflate as this
will weaken the product and voids the warranty!
The use of pressure gauge is recommended!
Only the lower swivel
(under water) shall be used for mooring of
the boat. The size of the buoy depends on
the weight and the total load it will be exposed
to. The dimension of the mooring iron bar
and swivel should be chosen in accordance
with the size and weight of the boat, weather
conditions, the currents and wave height in
the area the mooring is intended to be placed.
Do not
expose the buoy to a load of more than
60% of its total buoyancy. Please also
consider additional weight / load caused
by marine growth, currents, wind and
waves.
Over-inflation will seriously
weaken the material, destroy the products
intended shape, reduce the lifespan of the
product and void all warranty. Please remember
to check your mooring for wear and tear at
least twice a year. If in doubt, ask for professional
advise.
Valves
(single)
The flexible all-plastic POLYFORM
valve is fitted into every POLYFORM product.
Valves
(double valve system)
F11
(and optional F8) is equipped with the Provinor®
Double Valve System (air in / air out). The valves
are moulded into the rope-holds, located on opposite
ends of the fender:
V10:
During inflation, a flap at the lower end of the
valve ensures little or no loss of air.
Securing the rigid plastic screw will then close
the valve.
The clear plastic inflation
valve =
AIR IN
The blue coloured deflation
valve = AIR OUT
V40:
Designed for easy pressure regulation and not equipped
with any bottom flap.
Inflate through the centre hole of the screw. (The
screw should not be removed from the valve).
Cleaning
Vinyl cleaner, mineral spirits or simply
soap and water may be used. Stronger chemicals like
lacquer thinner or acetone will
irreversibly harm the products by breaking down
the chemical composition.
Marking
Waterproof marker pens are widely used,
alternatively, special paint for silk-screening on soft
PVC may be used.
Storage
If products are stored for a long period
of time, the boxes should be opened and the valves should
be opened. It is also adviseable to inflate the products
slightly.
