Back to the Halcyon, what people have not said is that it may not be deep, but it's a wide keel, must be over a foot, with lead ballast, so there is a large mass low down. It is moulded from a wooden Diamond class yacht, not a fibre glass designed hull.
If you're looking for that kind of boat, have a look at a Cutlass 27 - prettier (well I would say that!) than the Halcyon but a very similar proposition and less well known so often cheaper.
