I see in other companies plans that typically a boat can be enlarged 10% without causing any problems. Is this true in your designs as well or how much longer can your designs be made without having problems. Specifically, I would like to lengthen the picnic launch to 20' if possible.In another post you said a 9.9 hp would move the picnic boat at 11-12 knots. Since this is much higher than the hull speed is the the extra speed attainable because the boat is so light or how did you come up with the speed calculation.
I also wanted to know which boats have the full size patterns.
This is a great site and I look forward to hearing from you.
