Sorry Scooby,

The Tornado and 49er are OD but they are not SMOD. Your Inter 17 is however SMOD.

There are varying types of OD from strict SMOD where you can only buy approved fittings and sails to SMOD where you have freedom of sailmaker, fittings and placement of, to boats such as the Tornado which can be built by multiple manufactures or even home built, but must fall within the build tolerances.

The Tornado whilst not SMOD, it is almost exclusivley made by Marstrom at present and is considered more OD than most other classes including Hobie due to Marstroms cosistancy of build. The Marstrom is also setting the benchmark for quality of build and performance.
