As a teaching tool, it's meant to be the simplest VPP that can run without even owning Excel. My emphasis in the interface was on the aero induced...
As Dolfiman points out, I neglected to say that the Heel angle is fixed to zero. This is reasonable for a performance dinghy I feel. I made a...
Here is a very simple Laser VPP in Excel in case it is useful. Laser & dinghy boatspeed - VPP...
The mainsheet also has to provide the outhaul force when there is no boom. If the sail shape is identical with or without boom, then the centre...
Using data from here http://sailboatdata.com/viewrecord.asp?class_id=5865 TWS for 22deg heel is 10kn, assuming boatspeed of 6kn, TWA 45deg
All of the following is approximate!! I can't vouch for the Selden RM calculator. 1. Righting Moment at 30deg...
Here are rough and simple estimates based on assumption of sailing at the same max heel angle, say 30deg. The tall mast should be heavier with...
Todor, I have modelled hulls by fitting NURBS surfaces to arbitrary 3D points by a least squares method. The surface does not pass exactly...
The working part of the bailer needs to project below the hull boundary layer to be exposed to faster flow / lower pressure. I think that is why...
Check symmetry of the rudder sections. Look for differences near the trailing edge because aft camber shifts the CoE aft, which increases tiller...
If it helps with planning, I'm interested in 16.110
