You don't need fiberglass.
The fabrics work a lot better with epoxy.
The wet out is fantastic.
The question a bit hard to answer since people use weights from one ounce up
to six or more.
A lot of builders only use tape on the inside. You can find the synthetics.

Once you use the fabrics you never go back to fiberglass

I am building a S&G canoe. I am going to use fiberglass cloth on the
entire outside for extra strength, and to prevent any checking in the
plywood. I'm useing 1/4" BCx plywood.

What weight of cloth would I want to use for this aplication? And the
next question, how would I decide that on future projects? Is there a
general rule of thumb for weight?

One last question, I know I need to tape the inside and outside with
fiberglass tape on the seams, but If I cover the whole outside with
cloth, do I still need the tape on the outside of the seams?

Thanks,

dave

Most general purpose fabrics are in fact fiber glass, and that includes
ccloth and tape.

Weights are expressed in ounces/square yard.

Most tape is about 6 oz.

They are not fiberglass and they also do not make you itch.
They are in fact' Polypropylene and polyester-

Twilk is referring to Dynel etc. They are excellent sheathing
materials. They are not as stiff as glass when dry, though IME, and so
are not used solely as structural materials. They do "give" a lot more
and that can be an advantage in composite wood/fibre work.

IIRC again. My main gripes we
- $$
- they were not as transparent as glass/resin
- they get "fur" when you sand them
