You must have at least the minimum number of fire extinguishers relevant to the
size of your boat and located near to the main fire risk points. Powered boats, or
boats with cooking, heating, refrigerating or lighting appliances must be
equipped with the minimum number of portable fire extinguishers according to
the following table:

BOAT LENGTH	MIN. NUMBER OF EXTINGUISHERS	MIN. FIRE RATING OF EACH EXTINGUISHER	MIN. COMBINED FIRE RATING EXTINGUISHERS
Up to 7m (23ft)	2	5A/34B	10A/68B
7m - 11m (23-36ft)	2	5A/34B	13A/89B
Over 11m (36ft)	3	5A/34B	21A/144B

The number of extinguishers may be reduced by one 5A/34B fire extinguisher
if there are no cooking, heating, refrigerating, lighting or fuel-burning appliances
on the boat, or if the boat doesn't have an engine.

Extinguishers made before 16 June 1998, which comply with the navigation
authorities' previous weight, number and certification requirements for fire
extinguishers, are exempt from this part of this Standard concerning minimum
fire rating and combined fire rating. Further information on previous weight and
number requirements for extinguishers can be obtained from the Boat
Safety Scheme office. [6.1]
