Has your hull the same depth as a standard Springer or have you made it slightly deeper? Some dimensions of the hull bottom would be helpful.

The hull was drawn using standard dimensions I just flattened the forward two sections of the curve, I wanted to see if it made any difference to the submarining tendencies, that I still don't know yet as it's only been in the domestic test tank, I must get her down to the lake.

Interesting as I have never quite believed the inverted aerofoil hull shape theory.

Well I'm convinced the inverted aerofoil shape produces a suction at a certain speed and I wondered if having flat areas may break up the flow under the hull when I get back from holiday I'll test her at speed at the lake.
