All SAMM racing is under the British RYA Portsmouth Yardstick Handicap System
(see http://www.rya.org.uk/racing/Pages/portsmouthyardstick.aspx).

These handicaps are those suggested by our calculation program at the end of the 2018 Autumn Series where boats had completed four races. The handicap used is 50% of that between the last PN used and the new PN recommended. For boats of the same class we have averaged the handicaps. We will continue to review handicaps after every four races each boat completes.

If a boats handicap has not changed it is either because it has sailed to its handicap or did not compete in sufficient races to provide enough results needed for the calculations.

Two man boats sailed single handed distorts our calculations so this is discouraged.

Important Note: If a boat is available with different sails then each sail plan will have a different PN (see Laser 1 which has the option of a standard sail PN 1097, the Radial sail PN 1139 and the 4.7 sail PN 1200). We are removing the need for boats to compete using the same sail configuration the whole season (except see below for spinnaker) but if the sails are changed, the handicap used will always be that which is the lowest. The results achieved will affect the future PN adjustment calculations so, if changing the sail improves overall performance during the series, the handicap will be forced lower.

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.
