Effective April 2005
Dispensations registered with the W.I.C.
- UKWA: Wayfarer World
Asymmetric: As of 31 Jan 2001, the UKWA has given
dispensation for asymmetric-rigged Wayfarer Worlds to compete with
Spinnaker boats using Traditional Rig.
- CWA: As of 31 Jan 2002 and until
further notice, Rule 35.5 of Wayfarer Class Rules will be changed to:
“When racing, not more than one spinnaker shall be used during a
single race.” for boats sailing in
any Canadian-based Wayfarer event.
- SWS: As of 1978, the SWS permits removal of all side benches when racing. This
changes Rule 22.2(e).
W.I.C.
approved interpretations of the Class
Rules
- UKWA, 2004: " In pursuance of rules
5.10 and 5.12, it is the responsibility of the owner of a boat which is
the subject of major repair or renovation to show that the original
shape of the hull has been maintained and that the materials used are as
close to the original as reasonably practical and of acceptable
specification."
It might
significantly help the owner's case, for example, if the boat was
measured *before* the renovation commenced, as far as that might be
possible. If the boat had previously been measured at some point in its
history then appropriate measurements could be checked. Measurement
could then be checked and completed when the renovation is complete.
Involvement of a class measurer would provide an independent check, but
it is important that the measurer should be able to inspect the boat
before work commences. Photographic evidence of how the work was carried
out might also support the owner's case.
