HST Onboard is a stand-alone program designed for use by bridge personnel in order to compute vessel-specific sailing state, stability and longitudinal strength information in any loaded condition. The program is supplied with data files, which define the vessel’s geometric shape and loaded conditions, including capacity data for all of the tanks. HST Onboard enables the operator to:

• Select and edit loaded condition information,
• Verify the vessel’s compliance with intact stability requirements, as set in the Stability Booklet
• Show and print reports, which may be used as the ship’s official record at the time of departure.

HST Onboard is an upgrade of Wolfson Unit’s Onboard Loading program, the first program to be approved by the United Kingdom Dept. of Transport’s Marine Safety Agency which performs all of its calculations directly from the hull form.
