One thing I neglected to mention and I didn't note that anyone else
mentioned, 'the boom hieght'.

If a pilot house is added to a boat either by the designer or after market.
This everiably involves raising the boom height. This either reduces the
sail area or may increase the mast height. Either way, the sailing
characteristics of the boat will be changed. The center of gravity is
raised, both by the boom/mast and sail height. The boat will be much more
tender under sail and roll deeper if additional ballast isn't added.

Generally, a dodger cause these problems to a much lesser extent since
their installation is not normally intended to provide full standing head
room. In most instance the design boom height is not effected since the
designer has anticipated a normal dodger and bimini.

There is one other advantage of the pilot house over the dodger, and that is
the structural strength is usually sufficient to handle the main sheet
travel on the roof top.

Just my thoughts. FWIW.
