I'll check it out. Thanks!

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?

Most canoe and kayak builders use 6 oz. cloth, typically one layer over
the entire outside of the hull and often a second layer over just the
high wear "football" area on the bottom. Another common and lighter
alternative is 4 oz. cloth.

Is there a disadvantage for the 4oz? not over the chines or the
bottom, but over the rest of the sides?

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?

No it's not necessary, but extra wear protection on the chines is a good
idea. The outside should be completely glassed for durability. How much
glass/tape you use on the outside depends on how rugged you want the
boat to be.

Ah.. okay.
