<div>Robert,Stability information plus a a weatlh of other data is in an excel spread sheet put together for a Cruising World article on rating cruising boats. The 382 did well. I might add. If you would like a copy of the spreadsheet send me your e-mail address and I'll send you a copy.Fairwinds and Rum Drinks,Vic C.

I would certainly appreciate an email with those numbers.

U.S. Sailing Association has several 382s in its Performance Characteristics Profile for the North American IMS Fleet. All 5 foot draft--one, it says, had no inboard engine. And a couple the displacement seems very light. Overall average for Stability Index (LPS, plus a factor for boat size and beam) is 123.8, with a range of 118.4 to 128.5. That average just barely makes it for offshore work--the new J boats have ranges above 140 and the old Alberg 37 has 139.9. We should not be complacent here. Ultimate stability of the 382 is not all that great. For my purposes, it is good enough. These ratings, by the way, are, I am told, much more accurate than the simple capsize screening formula.
Terry,
In all fairness to the M38?, LPS of 118 to 128 deg is very good for our shallow draft,keel and rudder configuration,
beam,displacement. The J-boat is for racing and designed that way, the Alberg(my second choice after a Morgan)has full feel, narrow beam,cutter rig etc...The Morgan is a better boat considering displacement to length,beam,rig.
I'm taking mine(when I'm done all those renovations I can't afford) south for a long time and all my research said this was the best overall boat to do it with,
Fair Winds...

Actually the J boats I was thinking of are their new, big cruisers. And I like my M382 too. It suits me fine, given I can't have my dream boat. But would you rather be in a big sea in an Alberg or a Morgan? In those conditions, it is no question that the greater stability of the older designs is preferred. Actually, the Alberg 37 was my first choice for a long time, then I went aboard a 382 and the choice changed. WE all make compromises if we can't afford a Deerfoot.
I would be cautious to place to much value to the LPS numbers. They are only a guide to help insure reasonalbe and safe designs. As a matter of fact, I have a friend who was sailing to Bermuda in a Alberg designed Bristol 35 with a friend in a 35 foot Hunter of mid 80 vintage. While in route, both boats were hit by the same rogue wave. The Bristol with its full keel and high LPS rolled 180 degrees. I do not know the numbers of these boats but believe that the Bristol has a much better LPS because it has less beam and more displacement. The Hunter only went over 90 degrees. To me, the fact that the Morgan was designed and tank tested by a notable naval architect to be a safe, sable, capsize resistent, blue water hull design is what is most important.
<div>Gentlemen,
I crossed the Atlantic in #046 this late summer. After all said and done, I love my boat! She's a stable comfortable sail - providing you reef appropriately, as you well know.
I experienced on the Bermuda leg 10 ft seas for 3 out of the 5 days on the aft quarter. She just zoomed, although the shortness of the waves would be uncomfortable for any boat.
From Bermuda to the Azores, the most notable was the last 48hrs - 35kt sailing, double reefed in 10-15 ft seas, scooting at 7kts with GPS registry of highest speed of 13 kts...surfing...again, never felt uncomfortabe.
From Faial to Sao Miguel in the Azorean archepelago, we encountered 40kts on the stern in a grand 10-15'following sea. I sailed it with a dbl reefed main alone at first and just a reefed furler for the last 12 hrs. Again, a grand ride...although my crew didn't like it.
The grand finale was 4 days out of Azores to Portugal, I sailed into a stationary low of "1012"(if you can believe that's a low!) with 20-25' swells, some breaking, from the north, 30-37 kts of easterlies with accompanying 5-10' seas on the nose out of the east. I sailed it for the first 8hrs then I hove-to in this roughness and even tried the sea anchor in order to rest. I was intrinsically sailing solo. My crew was down with mal-de-mer let's say. I wanted to rest so I agreed to stop.
Long story short, I trusted my boat. She made me confident. She never heeled more than 35 degrees even at her worst moment.
Was it good boat handling - I don't know - but she rode it out beautifully and I never felt fear. That's what it all about if you ask me! I trust my/our Morgan's. Need I say more?

Tony--were you using windvane steering, and if so, which one? Were you satisfied with the performance. I have only used my Monitor a few times and I have not gotten it to steer consistently well. I am sure it needs some adjusting of some sort.
One other point: what was you technique for heaving to? what sails did you use and how rigged?
Thanks.

Tony, It's good to hear that the M382 is very sea kindly and is reasonably comfortable to sail in heavy sea conditions. Lacking first-hand information, I've more-or-less believed my eyes and gut feelings that Brewer's design was seaworthy and appropriate for blue water conditions. Thanks for confirming my beliefs!
You mentioned setting a sea anchor to get some rest. I'd be interested in hearing some details on that event. For example, what size sea anchor did you use? How was it set -- straight off the bow, Pardey Bridle, or? What did you do to prevent chafe? Did the sea anchor work as expected or were there surprises? Any recommendations?
Thanks in advance for whatever you can share.
