Theoretical Maximum Hull Speed Calculator

As a sign up bonus I am now offering a "theoretical hull speed calculator" With a displacement hull (sailboat) you can only go as fast as the length of your hull at the water line allows.

There is much debate about this maximum. Sometimes I have gone faster than my theoretical maximum. Was I surfing? Maybe my GPS was out.

This calculator is for a fun idea of what speed you might expect from your sailboat.

(I created these myself so they are free of any viruses or nasties.)

I have included the spreadsheet in 2 formats:

ODS, that will open with free open source programs such as Open Office or my current favorite Libre Office.

XLSX, that will open with Microsoft Excel (2007) and later. A free Excel reader can be downloaded at Excel Viewer.
