I was wondering what would be the best resistance to use for a RORO Ferry -the Delft Series or KAPER?
Neither- they’re for different hull shapes and sizes.
Look for Hollenbach or Holtrop-Mennen.
Ahh OK – thanks
Is this something Delftship can calculate, since I cannot see it as a option in the resistance Calcs sheet
No, DelftShip cannot calculate the drag using those empirical methods.
This functionality is planned for a future release, but I can not give an expected date of release yet…
OK Thanks – look forward to this!
Look for the software Freeship in the web, downloaded and isntalled, then sabe the file that you have in delftship as versión 2.6, that file can be opened with Freeship, and Freeship has the option to calculate the resistance with several methods, including Holtrop-Mennem, and Hollenbach….
Hope this helps
