Laser Cutter Cutting

Fibreglassing over foam to build a boat - how to do it right?

I am building a CAD model of a boat which I will be slicing up and have plywood spants cut from it by a laser cutter. I'll then assemble the plywood spants in 3D and fill the gaps with foam. Then I'll put fibreglass over everything.
It's supposed to end up being a mix out of a jetski and a sea kayak, about 6 metres in length, powered by a 2 to 3 HP outboard motor, for commuting on a bay in southern NZ (salt water).
Does anyone know how to prepare the foam for the fibreglass, or do I just lash it on and sand later, using filler till it's smooth?
Maybe any links known to relevant sites?
Cheers.

I built a canoe out of wood that I fiberglassed over. Clean the foam with a solvent that won't melt it then you drape the fiberglass cloth over it and brush it down with resin (mixed with hardner). Hard part is to make sure you dont have any air between the cloth and whatever you're putting the cloth on.

Start at one end and work your way to the other end with the resin. so you've always got a wet edge to continue on with. After it dries (a day or so) light sanding, wipe it down to get the dust off of it and make sure there is no oil and go at it again with resin. It should take 3 or 4 coats to completely fill the weave and get a smooth finish. Then you can paint it whatever color you want.

How does a laser cutter work?

Is it possible to use it in your house?
How do you trace and cut the picture exactly?
Do you control it or does the machine do it by itself?
So many questions...

We have laser machines to engrave photos into crystals. It is not exactly cutting, but the principle is the same.

To have precise cutting or engraving, you need computer control. Without computer control, cutting is possible, but it will not be pretty. Engraving is impossible without computer control, since you need to arrange millions of dots together to form the photo.

For laser cutting, you essentially heat the metal (or whatever you are cutting) to vaporize it. For laser crystal engraving that we do, the laser beam is focused inside a crystal, where its intensity is strong enough to cause a structure change. The surface is not changed because the laser is not focused there.
