IOM ( International One
Meter )
This is the class with the biggest fleet in the club, almost all
our members sail the IOM as well as other classes.
The International One Metre class is the fastest-growing class in
the world. This class was aimed to be a simpler, less expensive boat. The
International class has a one-design rig, and has minimum weights
on the keel and overall, and restricts the hull material. The net
effect of these differences is that the typical cost spiral of
lighter weight, and more expensive materials and manufacturing
processes, is arrested. This allows amateur designers and
builders a chance to design and build with little concern that
they are building in a disadvantage due to weight. This is a
feature not found in any existing class and is one of the
reasons that the class is so popular around the world.
Class Rules
10 Rater
The Ten Rater Class of model yachts is based on the length by
sail area rule of 1887. Shortly after this rule was adopted for
rating full size yachts, models began to use the rule as a basis
for new classes. With a one inch to the foot, or 1/12th scale
difference, the Ten Rater size of model yacht was a popular
choice for its ease in transporting, and reliable performance.
The early days were all free sailing under progressively better
devices for automatically controlling the rudder to hold the
boats to a straight course. While hull and sail design underwent
similar development, the Class gradually gained a reputation for
speed.
This tradition continues today under radio control, with modern
Tens employing the most advanced design innovations and
construction materials. The present rating Rule allows the
greatest freedom to experiment with performance improving design
and technology within the size limitations of the Rule. This
allows the Class to offer fair competition between designers,
builders and skippers. The Ten Rater Class is unique in its
method of "rating" yachts. The only two parameters that
matter are the waterline length of the hull and the total sail
area.
Below these powerful rigs, Ten Rater hulls are wide open to
experimentation, except to the use of multihulls, tunnel hulls
and off-centre or retractable appendages. Only the waterline
length controls the size of the hull, and that may vary in
reverse proportion to the size of the rig. This allows Ten Raters
to be highly specialized for exceptional performance in even the
most extreme sailing conditions. Whether your local conditions
are calm waters with light winds, open ocean waves with strong
gusts or something in between, there are Ten Raters ideally
suited to excel in your local waters. Hull construction materials
and techniques are often hi-tech and state-of-the-art, although
modern wood construction may still be used by fine craftsmen, to
produce competitive yachts. The greater emphasis is on design innovation with a steady stream of new ideas coming from the
drawing boards, or computers of both amateur and professional
designers. Being the fastest and most technically demanding of
all monohull model yacht classes, the Ten Rater is not a
beginner's boat. It is more the "Major League" of the
sport of model yacht racing. This gives the Class a relatively
small population in local areas, but a world wide popularity
among seasoned veteran skippers, who enjoy the challenge of
competing at the highest level. With the recent introduction of
several entry level model yacht classes, more skippers are
discovering the sport than ever before. As many of these classes'
earliest members are already looking for greater challenges,
there has come a renewed interest in the intermediate and
advanced classes like the Ten Rater. This has made for some new
fleets and the growth of existing fleets which insures the Class
a bright future to match its long and illustrious past.
Class Rules
A Class
The A Class is the largest
and most graceful of the R/C yacht classes. The class is based on
a similar formula to that used by full size 5.5 metre yachts.
Length overall can vary between 1.65 and 2.3 metres (65-60
inches), and weigh
between 11.3 and 23kg (25- 50lbs). Average weight is now around
13.6kg (301b) and it can easily be handled by
one person. Most A's can be transported in a medium to large car.
The A class is a popular class in many states and is large enough
to handle any conditions. The A is administered by its own
International Class Association.
