Bigfluke (Steven Loui - President of Navatek LTD) used the 25 seafari hull to research and develop his 9m SAM hull (Seakindly, Anti-Slamming Monohull)
The pic above is a 25 seafari with Weisman outdrive, surface piercing prop and 480 hp Yanmar engine.
This isn't the seafari but it's a video of one of those drives in action
