Stability index

[nortonbuffalo]

I own a Jeanneau 44 Sun Magic and I am looking for a stability index for the boat. When they made these boats in 1990 it was not a requirement to have the index. Does anyone know the stability index for the boat and can I get a copy?

If you have not already tried I would approach the designer:

If you are successful do let me know and we can archive for future reference

You might try this link

www.sailingusa.info/cal__avs.htm

Not sure if you want the angle of vanishing stability, or the whole chart. This link will give you the vanishing angle. It also has clickies to figure out hull speed, SA/disp ratio, motion comfort and 11 other factors folks like to know about your boat. Please note, you will need the numbers for your boat to plug into the formulas for this to work.

Also, either the folks I linked to, or ussailing.org for about $100 US have a way of printing this info, again, you have to supply unless they already have it, along with a speed chart for different wind strengths etc too. I'm recalling that US Sailing has this vs sailingusa which I linked as part of a rating/potential speed pkg.

Check your local Yachting Association. If they have assigned a rating there is a stability index on file
