Maybe snowboard would be a better analogy, Steve.

A Cat is one piece essentially(with some flex). One rudder is like one edge in that it's doing most of the work at a given moment. Mary Ann on the top of the Camden Snowbowl a few years ago, Penobscot Bay beyond.

- Just watched the CG video. Now I got even more questions..
- More from the Alpha website.
- Tarjan is a master of spin

- A fertile field for critics. Here's the account from Doane....
- refreshing to have somebody reporting from the bilge when one of these boats is abandoned.
- Charlie replies to the sailing forums Peanut Gallery...
- As usual, an excellent, measured analysis from John Harries...

- The definition of "massive"....
- I don't think it was cutting corners
- Forces only increase in reality not in direct proportion to change of weight, speed, area, etc in direct proportion
- I very much think it was cutting corners...

- I know both Hank and Charlie and I have one question for them . . .
- I think Hank and Charlie would argue with you that they were not in the Atlantic in February...
- Exactly...
- Your unexamined beliefs are showing, Jon
- What are you sailing, Mark?
- A Manta 40
- You're making the wrong generalizations
- I dunno
- Well you are right about that...
- I dunno
- "Unexamined", perhaps - but not necessarily unobserved...(grin)

- if there was ever a case for the owner picking up the rescue bill, this is it.
- I think Hank and Charlie would argue with you that they were not in the Atlantic in February...
- Charlie Doane posted an excelelnt account of the abandonment at
- I would have thought that the boat could have been sailed
- Now, after all this talk...
- I have the price list
- Well those are tiny little rudders, surprised they noticed them missing...
- The rudder size is not unusually small at all
- Agreed
- Two of them -- I wonder about that...
- forereaching depends on sail balance
- They aren't evenly loaded.
- I still don't see the point
- Even if you don't turn, the rudders see different forces, Mark
- I have agreed with you that mathematically, the rudders see different forces at different times
- Often the easiest analogies are extreme as examples ;^)))
- I don't buy the ski example in any form
- Not only
- Didn't they dive under the boat and look, as I recall.

- The owner stuck his head under and looked

- Here is a monohull example
- Those rudders are a compromise required by shallow draft. Nevertheless, the Alpha rudders were under bui
- Of course it is a compromise
- So I have become more interested in this shaft diameter thing
- Can't sit still any longer...
- Many monohull spade rudder shafts are seriously undersized.
- Mark, do you know another Manta 40 owner on Doublewide
