Stancraft boat has spray rails from bow to front of cockpit
but I think there needed when you have 625hp on tap :
StanCraft Torpedo Viper V10 625hp. think i might build mine as a stancraft version.

Hi BigAlio
Thank you for the you tube link, some very nice boats.
The double seat SG&K with the motor up front was especially interesting.
My single seat model preformed spot on straight up.
I would drop the sides down from the bow and add in some hidden spray rails, has it is a very wet boat at slow speed and cornering.
