The IMS Editor is Windows-based software primarily used by measurers to record, store and distribute IMS measurement data. It is compatible with the ORC Manager software used by rating officers for production of ORC certificates, as well as its designer's version that includes complete calculations using the ORC VPP (Velocity Prediction Program).

The IMS Editor covers all measurements of the International Measurement System (IMS):  sail and measurement inventories, rig, flotation etc. It can be used to record complete or partial measurement data, including the ability to "merge" measured data with already existing. The measurer can print the data as a formal measurement record, and submit them digitally as a data file (.dxt) to the rating office.

For simulation and testing purposes, the software is also used by owners and project managers to submit data to designers, who then use them as input for the ORC VPP software.

The latest 2024 version includes:

  • Set Class, Designer, Builder, Measurer field size to 50 chars
  • Add measurer email in editor
  • Set CertNo size to 20 chars
  • Validation for coexistence of measured freeboards flag and club displacement
  • Validation for PLM<2000
  • Added Adjustable Mast Foot
  • Carbon mast field replaced by "Mast material" drop-down with aluminum, carbon and wood options
  • Mainsail furler field becomes a drop-down with options No, In mast, In boom
  • Various minor fixes and improvements


The 2023 version includes:

  • Added "skeg" as new type of appendage.
  • Added strip codes (1=root strip, 2=appendage retracted). The root strip code is mandatory to exist in an appendage. For existing offset files without a root strip code, the first strip is assumed to be the root strip.
  • With the addition of appendage retracted strip code, fraction field is no longer needed. However it will be maintained for a limited period of time.
  • Additional offset file validation rules, to avoid VPP crashes or erroneous results.
  • Added validation for PD range, according to rule.
  • Added "Rotating mast" field in editor and the certificate.
  • Migration of CEXT to 0.25 for CEXT=0.50. It is now flagged and shown on the certificate as "Loose lifelines". This flag allows for automatic changes of CEXT in the future.
  • Various minor fixes and improvements.

IMS Editor is also accessible in ORC Sailor Services.
