The International One Metre class is the fastest-growing class
in the world. This class is distinct and different in purpose from the US One
Meter class, and complements the International Marblehead Class as 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 AMYA class, and is one of the reasons that
the class is so popular around the world.
The International One Metre class is "recognized" by the AMYA.
In order to register boats in the United States, use the standard AMYA
procedure and fee of $7, and send to the Class Secretary. In return for your
application, he will issue you a unique registration number. According to the (
http://www.radiosailing.org) International Class Administrative Rules, the last
2 digits of your registration number are your sail number.
Official Class Measurers are available throughout the country.
For more information contact the Class Secretary.
AMYA Class Rules

This System shall be effective as of January 1, 2012.
The System shall run continuously, so it can be applied at any time.
The ranking of Skippers as of six (6) months prior to the Restricted Event

Skippers wishing to participate in a Restricted Event must complete an
expression of interest form as explained in Section 9 below.
2. Skipper Eligibility
Ranked Skippers must be AMYA members in good standing at the time of any
Ranking Regatta to qualify.

sail identification. A float tank is strongly recommended; however, the class is
aware of the logistics issues. A float tank is mandatory for National
Championship Regatta Measurement.
4. Ranking Events

immediately following the last Ranking Regatta counting toward the prior
Restricted Event. The last qualifying Ranking Regatta shall start no later

Any Ranking Regatta in progress on the day of the cutoff will have its results
counted in the current Event Cycle.
Every Regional Ranking Regatta and USA National Championship Regatta
shall be a ranked event unless the organizer specifically requests that the
regatta not be included in that Event Cycle. This request is subject to
approval by the NCA Secretary.
Regattas within Canada may be designated a Ranking Regatta and utilized
within this Ranking system.
Events held in British Columbia area, Toronto and Kingston (CANADA) shall
be part of Regions 6, 2 and 1 respectively.

5. Rank Scoring
The top five (5) scores of Ranking Regattas in an Event Cycle shall be utilized
in the calculation of a Skipper's ranking.
Only three (3) scores from Ranking Regattas held in a single region may be
included for ranking purposes during an Event Cycle.
A Skipper's rank shall include at least:
1 (and no more than 2) USA National Championship Regatta(s),
1 (and no more than 3) USA Regional event(s), and
1 USA Annual Club Ranking Regatta (non-Regional and non-USA
National Championship Regatta), which must be included in the top
five (5) scores counted in calculating a Skipper's ranking.
USA National Championship Regatta scores shall be given an additional
1.2x weight, USA Regional Championship Regatta shall be given a 1.1x
weight and a USA Annual Club Ranking Regatta shall have a 1.0X weight.
To be a Ranking Regatta and count towards a Skipper's ranking, a minimum
of ten (10) boats must start a race during the regatta.
All Ranking Regattas shall have a scaled point system with an initial base of
100 points for the 1st Place in a ten (10) boat fleet with the base increased by
one (1) points for each additional participant.
A Ranking Regatta's point value is driven by the number of starters as set
forth in the following chart:
# of starters: S
1st Place Score: TP
11 12 ...
101 102 ...
20 21 ...
110 111 ...
Scores will be rounded to the nearest whole number.
The ranking score for each participant utilizes the following formula in which:
TP = Total points (1st place Score) for the event based on the number of participants in the
S = # of starters (number of boats that actually participated in the Ranking Regatta)
F = Finishing position in the Ranking Regatta
Finishing place in most recent USA National Championship Regatta.

7. RD Ranking points through "Event Redress"
If requested in writing to the NCA Secretary within 30 days of a Ranking
Regatta's start, the Race Director ("RD") and any other indispensable person
necessary to the proper running of a Ranking Regatta as nominated by the
RD, may be awarded average finish "redress", which will consist of the
average of their finish positions at all Ranking Regattas they have participated
in over the entire Event Cycle, which in turn will be converted to a "Redress
Score" for the Ranking Regatta missed as calculated in Section 6. To be
eligible for consideration of Event Redress, the person requesting such must
have participated in at least five (5) other qualifying Ranking Regattas within
the Event Cycle.
Only one such Event Redress within the Event Cycle may be applied for the
individual's total ranking score.
The average score will be recalculated after every Ranking Regatta.

8. "Event Redress" for US skippers at World Championship, Continental
Championship(s), or other Restricted Event
Just as a RD may request Event Redress for a Ranking Regatta he or she was
unable to participate in due the active role he or she took in making the
Ranking Event possible, so too can the US participants in the World
Championship, Continental Championship(s) or other Restricted Events who
are unable to attend certain Ranking Regattas in the US while preparing for or
returning from a Restricted Event abroad, subject to the following rules. Any
US Ranking Regatta occurring within thirty (30) days after the World
Championship or within thirty (30) days before or after any Continental
Championship or other Restricted Event may request "Event Redress" by
requesting such in writing of the NCA Secretary within 30 days of the Ranking
Regatta to be missed.
The same rules for calculating the "Event Redress" score through an average
of finish position, as described in section 8, shall apply.
To be eligible for this "Event Redress", the Skipper must have at least five (5)
finishes in other Ranking Regattas during the Event Cycle.
9. Expression of interest

Expression of Interest applications, the NCA Secretary will confirm and publish the
entrants on the NCA web site.
