And the reason for staggering is to avoid hard spots. A hard spot creates a neighboring weak spot and stresses in hulls find those places to crack. This is why we don't end four or five layers of glass at 4" overlaps because you'd have a massive hardspot

Another reason for staggered lengths and no hard spots is fairing. Fairing over a hump takes a lot more material and is ultimately less fair. Of course this matters less than a weak spot/strong spot, but points out the sand through problem...

That transom might be a bugger to place as a single piece. You might need/want to build it in place. This can be done by clamping with bolts...iirc there is a tutorial here on it.

If there are seams due to size limits of the core; you can butt join, but must stagger joins.

Also add about 4-6 ounces for roller loss to your calc. A paint roller works well for transom wetout because you can load up a good bit of resin, but that is the downside. I use a squeegee to get resin back out for use on other things, but oftentimes, the rollers will be startimgnto cook.

No. Glass is layered largest first to avoid cut through when sanding.
I have been around a number of professional glass folks who stagger glass smallest to largest. As I said it is a matter of debate. If a NA were to give guide lines I would then go that way. In the end I am not sure it is going to matter all that much.

You are too nice a guy for me to want to enter into a bunch of polemics. I'd rather meet you for some fishing in Alaska than worry about the order of things. However, another reason I like to do the biggest panel first is I am older and I get tired at the end.

There are guidelines, but fortunately, none of us are required to build to them.

I feel the same way. Never want to be some sort of keyboard cowboy. :wink:
If you ever are able to get up this way I would be offended if you did not give me a chance to take you fishing :D
