LPS and AVS values for DE32'? General Forum Forums

Nigel Calder's Cruising Handbook refers to values LPS (Limit of Positive Stability) and AVS (Angle of Vanishing Stability) as well as things like the plane of buoyancy at the actual current waterline at any given angle of heal ... quite good stuff! These values are derived from the actual beam at the waterline (as opposed to the specified beam overall), etc...

Has anyone seen a post which specifies these values for the DE32?

Earlier this year, I ran the number of length-displacement and beam-displacement ratios and other simple equations from the book Desirable and Undesirable Characteristics of Offshore Yachts and while the DE32 has a great reputation for being an excellent offshore design (small cockpit which sheds water, companionway above the deck, low CG and bomber hull and deck build), I get a little concerned that a 5500 lbs keel with a 17000 empty displacement seems a little light... add water and fuel and that's certainly better.

But then consider a capsize - when inverted, the DE32 is quite the flat bottom boat. People I met capsized in a Formosa 51 - similar lines with the big Wine Glass Stern - they put their feet on the shoulder and rocked the boat until she came back over...

My experience with Alicia's Wrath (my DE32) off Big Sur in 40-45 kts proved she's a strong and stable boat... and the 'Alicia' in her name is the 1983 hurricane which landed in Galveston, TX - so she survived that ordeal with a little bit of hull scrapes, but was fixed up without too much effort.

But in the end, the numbers should tell a story about stability and what to expect in rough weather conditions.
