why do (some) people hate bilge/twin keels

Bilge / Twin, not sure what the difference is, and those with two plates of metal strapped to the bottom!
I just love the flexibility of mine with aerodynamic encapsulated keels :)

Seems to me sailing with 20degrees of tiller is just plain wrong, unless the boat is doing something very odd. Sounds like a boat designed for a fin keel with a poor bilge keel adaptation, or a need to change sailplan.
22knots true is probably above the point where the rig is optimised.

I have sailed all three flavours of Sonata, none of them are bad boats IMHO.
Is the Sadler designed by the same bloke? But it's masthead rig?

I believe the comparative tests were performed with Sadler 32s. This was one of the earlier Sadlers and possibly not originally designed with twin keels in mind. On the other hand the twin-keeled version of the later Sadler 26 sails very well.

But what were you doing in Portrush?? :)

Pleiades has been known to snuggle down in Portrush:-

And of course what she does there mostly is enjoy the vagaries of Portrush weather

The Norn Irn Coast is perhaps not what where would expect a bilge keeler to be at home but Portrush Harbour is quite shallow at the inner rows of mooring buoys where a deep fin or long keel would not take kindly to low water springs.
And that little bilge keel Snappy makes the most of the Port

Interesting link to what seems to be a PBO article from 2005 from your Wrighton url:

Yes, isn't it. The author, Andy Cunningham, was British Hunters' Sales Manager at one time I believe. He refers back to the work of Lord Riverdale who is credited with with inventing the twin-keeled cruising yacht. He was a Sheffield industrialist and his later boats, all twin-keelers called Bluebird, were built of steel. He cruised them all over the world. He met Fred Rayner on the beach at Beaumaris in the early 60s. Rayner was fascinated by Bluebird's keel configuration and went on to found the Westerly company with the Westerly 22 & 25ft twin-keelers.

I sailed on the East coast and there wa a preponderence of bilge keels for obvious reasons. I suspect there are few of them in the Solent again for obvious reasons.

I don't understand why people knock AWB's, bilge keels or anything else, boats are designed for different purposes and and people make thier own choice for good reasons.

They're much appreciated on the West coast too!

One of the advantages of buying our first boats before discovering the Internet was that we were able to enjoy our sailing in blissful ignorance of the terrible mistakes we were making.

A late bid for the Forum post of the year 2012, methinks!:)
