Yacht Design Softwareby Hans Zwakenberg
Hi sailor, interested in yacht design software, are you?
If you are, please check our this site, which offers HullDrag/32, a free computer program that estimates a sailing yacht's hull resisitance.
HullDrag/32 can do quite a bit more than just estimate a hull's resistance, but you have to read the rest of this yacht design software site to find out.
Summary of what to find on this site:  | HullDrag/32, a free sailing yacht hull resistance calculator program | | | Heel_It!, a forthcoming utility to help you evaluate how hull wetted area changes due to heel angle | | | | |

| HullDrag/32 yacht design software explained | |
| HullDrag/32 is a sailing yacht hull drag calculation utility that estimates the drag of a sailing yacht's hull, keel and rudder. In addtion, it offers optimisation of Cp and LCB for speeds up to Fn=0.45. A new release of this yacht design software is in the works which will offer optimisation for speeds up to Fn=0.60. The new release also optimises the value of LCF. | |
| Want to test this free yacht design software? | |
| For all of you interested in sailing yacht design, yacht speed optimisation, drag reduction, or whatever, I envite you to download and evaluate HullDrag/32, the free virtual towtank inside your PC. | |
| Site requirements | |
| This site is designed for low-bandwidth access. Please consider the following: use a minimum screen resolution of 800 x 600 pixels, more doesn't hurt. Please enable JavaScript, it's used for the menu system only. | |
| Amazing number of downloads | |
| In the initial period between July 1999 and May 2000, HullDrag/32 was downloaded almost 900 times. In the years that followed, interest remained high, with download numbers in the thousands per year. This amazes me to no end, as this hydrodynamics computer program targets a very specific audience indeed. I thank you all for your interest. | |
