Handicap Rule
IRC ENDORSEMENT Protocol (requires official measurements):
As race organizers may elect to require endorsed
ratings, the following measurements will need to be taken by a US
SAILING official measurer before the RORC can Endorse the IRC
certificate for your boat. As such, upon receipt of your completed
application, we
will then follow up with specific measurement requirements, which may
include any & all of the follow, or some lesser combination there
of. Please
arrange for the measuring to done in accordance with IRC Rules
consecutively to submitting the application.
Weighing
 |
Out-of-Water
Setup- Empty
Weight is the weight of the boat in the dry condition as detailed
in the following: Requirements
(MSWord, 54kb) It is important to please make sure your boat
is set up before the measurer arrives to save time and expense. |
The
ONLY loose items may be a spinnaker pole, bunk cushions (if carried when
racing), and hatch boards. EVERYTHING else including anchors and safety
gear, etc. shall be OFF. See above.
|
Measuring-
Once
the boat is verified to be in the Empty Weight condition, a official
measurer may weight the boat using a designated & calibrated
load cell. Single point measuring is preferred. |
Weighing
is very often beneficial in rating terms because for un-weighed boats we
take a 'conservative' (i.e. light) view when there is any doubt. Even
for boats with IMS certs, we prefer a boat to be weighed eventually
because of the unfortunate variability in IMS DSPM.
