Is fiberglass cloth stronger than mat?

Fiberglass mat has a higher density than fiberglass cloth. Fiberglass cloth is a layer of woven strands. It is strong, with a uniform appearance, and is used where the look of a project is important. The woven fibers do not intermesh with the fibers of other layers of fiberglass cloth.

When to use Dynel as wood strip sheathing?

Dynell is very strechy and will tend to do so when the hull is strained. If you have abrasion concerns I have used dynel strategically with MAS epoxy in the areas of the for-foot subject to the greatest abrasion. This is a nice way to go as it is easy to repair.

Which is better for boat hull Dynel or glass?

Dynel does cover compound surfaces much better then typical glass layups and provides more abrasion resistance then same. I’d skin the hull in glass and hold the final layer for Dynel if you really require the additional help. It depends on the layup schedule meant by the designer.
