Sailing a C&C32 is not a "sea trial".

If you're going to play the expert, you need to UNDERSTAND the terminology.
There is only one kind of "sea trial", it involves sailing and inspecting
the boat you intend to purchase, not the same model.

While sailing the vessel one plans to buy is best, sailing a sistership is a
reasonable alternative.
Let's look at why this is so.
The main reasons for a sea trial are to judge sailing characteristics and test
a vessel for obvious problems. In an era of production boats built by major
builders, boats of the same design generally exhibit identical sailing
charateristics. This is the essence of one design building. So sailing a
sistership(s) will generally bear out sailing characteristics. In the case of
Alien, her history was known to me and she was thoroughly gone over. In the end
I had some idea of how she would sail and had no concerns regarding condition.
For all intents and purposes I had a sea trial. Clearly this is not the case
with boats built one off and I would want a sea trial of certain makes, such as
Cheoy Lee, irrespective of a detailed survey.
