Radio Yacht Classes
The club accepts a variety of classes within our membership, Below are some
descriptions of the various classes of yachts.
These boats are light, responsive and very
fast. This international class rule is ‘open’ allowing great
design and construction freedom within the main speed
determining parameters restricted to 1290mm length, 700mm
draught and 0.5161 square metres of measured sail. Ultimate
efficiency and excellent performance has developed within
these simple limits.
Current hull designs are very narrow with
stability coming largely from the deep fins. This has
allowed most post-1991 designs to remain competitive and
give very close racing. Simple swing rigs allow some designs
to be rigged very easily. Based on the width of the back
seat of a car, the rule makes these boats easy to transport.
Second hand boats are good value for money.
these boats are of a heavy ‘type’, there is more flexibility
to create lighter ‘models’. Nevertheless they are big boats
and a fleet of radio ‘A’ boats are an impressive and awesome
sight! Boats are typically 2 metres long, weigh between 14
and 25kg, carry about one square metre of sail and enjoy a
long competitive life.
are not limited in length and have overhangs beyond their
waterline making them light, sleek, seaworthy and fast. This
ISAF RSD international rule is based on the 1887 ‘length and
sail area rule’ which allows short waterline length boats to
have a big sail area and longer waterline length boats have
smaller sails. It is an ‘open’ rule with great freedom to
develop design and construction, particularly in rigs and
sail plans. Any boat can be measured as a 10 Rater and
several Marbleheads have been successful in the class by
conversion with just one larger rig giving 40% extra sail
area. A typical 10 Rater is approximately 1600mm long,
weighs 6kg and carries one square metre of sail.
International One Metre
are light, responsive and fun to sail. This is the most
popular of the four international classes and is sailed at
most clubs. The class rule is ‘closed’ and many aspects of
design, materials and construction are restricted in an
attempt to promote close competition. However the rule is
designed to allow the DIY enthusiast some freedom to
construct an inexpensive and competitive boat. The important
speed related criteria restrict measurements to a maximum
of 1000mm, a maximum draft of 420mm, a maximum fin/bulb
weight of 2.5 kg, a minimum overall weight of 4kg and 3
