[PCW] Sailing cats with engines

[brian eiland]

Speed:
Primarily you need to look at how much power the existing vessel has, how
fast
you want to go, and eliminating the considerable squating you get in the
stern. You might also remove the sailing rig for windage purposes, if you
never intend to use it, or keep it in case you decide to 'motorsail'

Agility:
The designer " was asked to grapple with some of the unique requirements of a
good sportfishing machine--the ability to back up quickly and maneuver with
agility--then mesh them with a hull design that would not only perform well
under sail, but also under power alone. The results are probably as close as
anyone could come to the perfect compromise."

"She converts into a highly maneuverable powerboat in about as much time as
it
takes to drop a bait back and hook a billfish in her teasers, and once under
diesel power, her widely separated, fully reversible props allow her to
pursue
even the most agile billfish with impressive agility."

"She backs down at over 10 knots without burying her two transom doors."

Do you have a vessel in mind?

 Some time ago on this forum someone suggested using a sailing cat as
a PC. I am curious. What turn of speed and agility could one get from
this kind of behaviour?
