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." <http://www.runningtideyachts.com/archives/TaraTour1.html> Do you have a vessel in mind?

TRx. for the interesting reply. No, I did not have a particular vessel in mind. Which ones would you consider for some an operation? rg.
