Please email us with your VPP requirements.
1. What is the definition of 'K-R Sep' found in the Flotation dialog, Keel group box ?
K-R separation is the mean distance between the leading edge of the keel and leading edge of the rudder.
2. I cannot run older .vpp files
The link with the underlying opsets (.ops) file may have been lost. Open the .vpp file and resave it to generate the opsets file, then run it again.
3. Does the program have a simplified input functionality?
Yes, the flotation parameters may be input directly in the VPP if the lines are not available.
4. How do I input a long keel hulform in the VPP?
The J Class option fundamentals are described in our paper 'Development of a Vpp based rating for J-Class Yachts'. In summary:
LPP - use the long keel option, this means that the entire hull, integrated keel and rudder are all one geometry, so no need to define keel and rudder.
VPP - in the Modelling page of the Flotation dialog, use the following settings
Otherwise you should be able to use the VPP in the usual way.
