shovel noes tunnel hull?

hi all just wondering if anyone can spare some time or shed some light on perhaps the purpose of this hull or any characteristics it might have?

I personally think..(uneducated in hydrodynamics) that it might be a good off shore vessel with heightened stability come stern with a wave piercing bow.
the angle on the bow is 120 degrees at the start of each sponson is 150 and the dead rise is on each sponson is 160. im not sure of the origin of this boat. i built this one myself from the molds that i bought. the guy i bought it off isnt aware of where it was originally built either.
thanks for your time.
andy.

ill have more photos coming up soon. just having some issues uploading cheers.

 

by the way its LOA is 10m and the beam is 2.25m

 

I like the extra photos, nice find and good luck.

I'll do a quick Google search, not holding my breath though.

EDIT: Not quite the same.

There is something called a Seafox with tunnel hull, but it looks like a smooth blend hull and cannot find good photos of it underneath.
