Fiberglass over wood planking
I apologize if this has been posted a million times, but I am new to this so I am curious. I am in the process of building my first large rc tug, its going to be about 3.5-4 feet long and weigh about 150 lbs, when fully ballasted. So I am wondering, why take all the time to nicely plank the hull just to fiberglass over it? can I just use wire mesh or staple the first layer of fiberglass cloth to the ribbing of the boat(making sure it is follows the contour of the ship of course), or do I need the stability of the wood -planking underneath?
