It looks like a great Spring or early Summer project. I think I'll try building one this coming Spring.

Chicken wire, unless completely embedded into the foam will provide little or no benefit and may create problems with the glassing.

Glass fabric over foam has been used for years to build boats and is a proven technology. Advancements have been made, but only in the form of the core (foam in this case) materials and the skin materials. Carbon fiber and/or Kevlar over honeycomb material is the lightest and strongest combination, but usually very cost prohibitive for this type of application - this is fighter jet technology. ;)

Using epoxy resin to bond the core layers and provide the skin "shell" is more than adequate for a layout boat.

Brilliiant man! I wonder if he gets much flex? I guess the deck and splash rails stiffn things up. I shaped a few surfboards in my youth and just might have to break out my old tools. A power plane makes short work on the foam but makes one heck of a mess in the shop.

Word of caution. Note that he used epoxy not resin. Resin, polyester or vinylester, contains styrene, the same thing that the polystyrene foam is made of. In short it will melt it. Also the addition of chicken wire prolly won't help the strength of the boat as the glass is alot stiffer then metal.:tu

The amount of weight a boat will support and stay afloat depends on displacement, which translates to hull size and shape. The hull will displace a volume of water that weighs exactly as much as the boat and its contents. Each cubic foot of water displaced weighs about 67 pounds. Adding foam (or anything else) inside an existing hull will not improve the hull's displacement. If you want a hull to be capable of carrying more weight, you would need to enlarge the hull in order to displace more water and still remain afloat.

So if the 6.5 bevertail weighs approximately 65 pounds, you would need to add about a cubic foot of hull displacement to counteract the weight of the motor.
