effects of radically modifying the stern

[bradles1330]

Just looking for the feasability for a project like this. I'm looking at taking a lobster boat-esque type boat, buying the plans for it, and rounding out the stern. The finished project will hopefully look similar to the robert frost hull shown on the zurn yachts page, the torpedo 38.http://www.zurnyachts.com/power.html
They build these right down the street and I love the look of the stern. I just don't know how much it will affect the performance, stability, and structural integrity of the boat if i do go ahead with it. I've been looking at plans such as...

I'd be interested to see what you guys all think about this. I've tried plugging it into free ship, but I just can't figure out how to work that program yet. Havn't had the time to invest in it yet...

The Robert Frost boat has more curve than a Glen-l or other boats designed for amateur construction. The cost of a set of plans is minimal compared to the rest of the construction. Also, it is more work and you may end up with a boat that performs badly because of your modifications.
