VELOCITEK SC-1 DISCUSSIONS

The information so far on the Velocitek SC-1 used in basic mode is that it conforms with the J/24 class rules. Some of the advanced features violate some class rules.

The relevant class rules are 4.1.3 and 8.1.5.

The SC-1 does not break any class rules if it records GPS tracks that are later downloaded to a computer and displayed there. It cannot be used to display position or VMG during a race.

4.1.3 A minimum of one fixed marine type compass of magnetic card or digital readout type capable only of instantaneous readout. (Compasses capable of displaying stored headings and/or performing calculations for storage of tactical information shall be not allowed.)

8.1.5 Use of Loran, GPS, or similar position fixing devices.

As these continue to evolve and the price point drops, it is something the class should revisit.  The J24 Association would welcome any input on the issue.
