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.

Hull sides / forward and transom are 1/4"ply bottom and deck is 1/8" ply, superstructure is 2mm ply,, so far only tested in domestic test tank(bath) no leaks and controls well, almost turns in the width of the bath with the fish tail rudder, now I'm back from holiday I'll get around to taking her to the lake.
