HullDrag/32 Yacht Design Software only runs in a Win32 CMD-box

HullDrag/32 currently runs in a Win32 DOS-Box only, meaning: it's strictly character based but needs the 32-bit environment that the Win32 programming API's offer.
The bottom line: it runs like programs used to run under DOS or Unix, but it needs Windows to do it. Progress indeed... ;-).
Whatever you think of it, it's temporary, as a Windows GUI based version is in development. Release date as of yet undetermined.

Update: Rel. 0.51 (beta)

The new 0.51 Beta version is a small improvement over the previous 0.5 Alpha.

It includes more meaningful error messages and the size of the entire download shrunk from 65 kilobytes to a meagre 23 kilobytes. Download the DOS-Box product here:
