All SAMM racing is under the British RYA Portsmouth Yardstick Handicap System (see http://www.rya.org.uk/racing/Pages/portsmouthyardstick.aspx).
Up until 2015 the Race Committee reviewed all PY numbers using the RYA PYS web site. In 2015 the RYA changed their system and we could no longer use it so we created our own Excel program that did the same. Gradually all the handicaps have become more stable.
To set those to be used for the Spring Series 2017 we have adjusted the figures to 50% of that recommended by our Excel program. New boats will still have their PN reviewed after every fourth race for the first season.
Important Note: Boats must race with the same sail configuration for the whole of the season but are allowed to reef in high winds. Crew numbers can differ without penalty but we discourage two man boats being sailed single handed as this distorts our calculations.
The different handicap for the use of a spinnaker has been retained at 3% difference to the norm in line with RYA guidelines. However each boat with a spinnaker option must declare if it will use its spinnaker before the first time it races and the reduced PN number will be used throughout the season. If a boat declares that it will not use its spinnaker and does so in a race, it will be disqualified.
