I think in Nick's book there are the offsets for a rounded deck (memory slipping away here) if there arent the offsets then he explains how, but im sure there is something.

But if your forms are set up already its quite easy to make your own round forms at the cockpit and make the whole deck fair with a few battens (strips), but keep in mind how much room you want for the legs.

: I am currently setting up forms for my Great Auk kit. I would like to round
: off the peaks on the bow forms to produce a more rounded forward deck. Any
: advice on modifying forms to keep the lines fair would be greatly
: appreciated.
