Construction
Your RIVER 460 is made of high-quality polyethylene plastic. The material is very impact resistant
and durable at normal temperatures. It is fully moulded with a tight cavity which gives the boat very
good buoyancy. RIVER 460 is designed with wide step/speed-rails and wide shine in the hull, which
gives the boat good planning properties, very good stability, and safe driving characteristics. Holes
in polyethylene plastic are difficult to close as ordinary adhesive systems do not adhere over time.
Therefore, under no circumstances should holes be made in the boat to install equipment yourself,
without first consulting with the manufacturer.
Use of heat:
Polyethylene loses its strength when heated significantly beyond normal temperatures. Therefore,
do not use open flames or other heat on board the boat. In the event of ignition or excessive heating,
it will produce heavy smoke (non-toxic), the plastic will become shiny, brittle and lose its mechanical
properties, and the boat will no longer meet the current requirements and rules for safe use at sea.
8.3
Stability
Your RIVER 460 has been designed according the requirements set up by the chosen design
category (see chapter 2) to operate safely and stably. In general, the RIVER 460 fulfills the
requirements of EN ISO 12217-3:2017 (Boats of length under 6m) about stability and buoyancy.
The hull is not designed to resist local damage caused by stiff and/or sharp objects.
In case the hull is damaged, immediate repair is necessary.
