: So if I want to lower the sheerline on the Cunningham S&G to about 7"
: from 9" at the rear of the coaming, can I just make this modification
: when I loft the panels? Will it affect the fitment of the aft deck and
: side/center deck panels?

: Since the aft and foredecks are flat, and lowering the sheer won't change the
: beam, I'm thinking they would still fit fine, and I'm thinking that if I
: fit the side and center deck panels at their same sizes, it will lower the
: front of the cockpit as well. Thinking I can see how that goes during
: wiring, and cut new wider panels for the hump in front of the cockpit if
: needed or cut a "cheater" panel for the centerline or something.

Please note, that lowering the sheer WILL change the beam since the side panels has a bit of flare.
Your deck panels will be to big for the new smaller beam, and trying to fit the original sized deck panels to a smaller beam will be difficult and probably change the shape of the hull.

I suggest you cut your deck panels a bit oversize, place them on the hull and run a pencil along the perimeter of the hull to mark the hull shape on the underside of the deckpanels. Then cut the deck panels to size.

: My thought is to loft the curves per the offsets first, then to mark a couple
: centimeters down from points and re-draw the curve lower to keep it all a
: fair swoop. Basically to make the swoop deeper around the cockpit region.

: Is that kind of modification something I can do by the seat of my pants so to
: speak? Any advice? How will it affect the weight the boat can carry? I
: weigh 210, it's not going to sink is it?

Your modification sounds OK to me. I would do it the same way.

: The image at the link below shows the original line in black, and what I am
: proposing in green. Not accurate or final, not to scale, but just to give
: an idea.

: I apparently saved the image with transparency, so it shows up funky here,
: click the link to see it on a white background.

: thanks!
