I'm rebuiding my boat interior and all the wood was rotted out so i've taken it out and replaced it all and now I'm applying the fiberglass over the wood. Will 1 coat do the trick or should I apply more? And do I need to put the fiberglass mat over the cloth for extra protection? I'm new to this and trying to learn from scratch any advice will be extremely helpful!

The cloth is the strength, the resin is the binder, and sealant.
Extend the the patch area at least several inches beyond the actual repair.
Like mentioned above, it needs to be planned well ahead of time, and needs to be done ALL at once.
Preparation is the key. Poor surface preparation ends in a poor job.

Resin has very little strength and its only purpose is as a bonder. The strength is in the fiberglass. Fiberglass cloth is stronger than the mat. The cloth is directional glass strands, the mat is random direction strands. Not knowing what weight glass cloth you are working with and what part of the boat you are applying it to makes it impossible to give professional instructions.
Cloth can be laid over a previous layer provided.
1: The prior layer is still wet.
2: The prior layer has been sanded if it was dry
Resin is only applied heavy enough to wet out the fiberglass. If you wish for a smooth surface of course apply enough resin to achieve a smooth surface. Sanding is required if you plan on painting the glass. Small areas a paint brush for applying resin works but for larger surfaces a paint roller is needed. In either case, work the resin down into the glass and work the air out. They make rollers for that purpose. They look like a miniature farmers disk. Acetone is your cleanup solvent. Nothing else will touch resin and clean it off your tools.
Everything you are working with is highly flammable. Use caution. Use plenty of ventilation. The fumes can ruin your lungs or worse, kill you.

You will definetly need more than 1 coat. I would think you would need several before it is strong enough. I would use the cloth to get the shape and then put the mat over that for another layer. The mat will use a lot more resin but will make it a lot stronger. You should be able to tell when the fiberglass is strong enough. Good luck!!!

You can't re-coat fiber cloth with resin after it hardens. The more layers of cloth you have, the harder it will be but it is all done at once. The surface you are attaching it to must be sanded and clean before starting. As much air and excess resin as possible must be removed before it hardens.
