Skin Thickness

Does anyone know the approximate thickness of the bottom FG skin back near the transom? Repair time. Thanks,

Chris

...by the title of this thread, I though you were going to start calling someone names!!

To my dismay---you were being civil and only asking a legitimate question.

I guess I need to check out the C-Dory Warranty thread for some more excitement.

Based on hull samples, it looks like about 1/4"+

Here's what they did on an '84 22-footer:

It appears that it's about 3/8-inch below the 3/4-inch plywood core; I highlighted the line between the core and glass for better visibility. It is also 3/8-inch in the center of the hull where it's not so complicated with running strakes and chine stiffening. Your boat may vary...

If anyone can tell me why this pic didn't come through in the post, please enlighten me. Seemed pretty straightforward, but...

Code should have looked like this:

I'll try again with a photo...

Chris,

Not knowing what you're running into with your boat, I thought I'd post this as something to look at if you're having transom/sole problems:

On my boat, I found that the last two feet of core and the glass below were bowed down about an inch. I've heard from Larry H and others that this is classified as "bad". It can make the boat handle poorly if it's out of plane by that much. If you have a long, say six-foot, straightedge you might want to lay it fore to aft in the cockpit and see what's what. I didn't notice the sag, however, until I cut the transom off.

Best of luck,

Tom Herrick
