Another consideration is how the boat will be finished. If it's to be bright
(varnished), then a carefully done scarph is the best choice. If painted, a
taped butt, as at http://www.instantboats.com/images/buttjoint700.gif , is
OK. I'd suggest cutting the cloth on the bias, so that all of its threads
cross the joint.
With a little practice, the scarph takes less time.

Graduating to my first multi-sheet stitch-n-glue... butt joints with blocks
are ugly, scarfing will throw off my sheet layout. Can I use a plain butt
joint, supported on both sides by glass and epoxy?

I taped butt can look good, too. Pygmy uses them on their kayak kits.
Maybe not as elegant as a scarph, but still in character for the boat.

What weight of glass is used? I've found taht its very hard to get glass over
8-10 oz. not to be cloudy.

Light tape (2 oz?) on the joint, with 6 oz glass over the entire hull. No
clouds after 4 years...

Since the inside of the butt is hidden, a wood block is used on 1 side for
strength. Though it does cause a minor straightening of the curve in the
hull, it is not detectable except under close scrutiny.

Why go higher than 4 or 6?? I got multilayers 6oz on my kayak (hull).
