The WizCat 130 Pontoon Deck Boat

There is no "perfect" boat design .... but the Wizcat 130 comes close.

The WizCat is absolutely unsinkable due to solid foam core pontoon  catamaran design. The WizCat will not sink or flip over.  With it's high floatation and 4" inch draft you can easily slide over those shallow  fishing spots. 

The 'secret' is Dupont Foamular or Dow Corning Blue Styrofoam (closed cell foams). One cubic foot of Dupont Foamular will displace 60 lbs of fresh water or 62lbs of salt water. Each pontoon (12' x 2' x 1') can displace 1,440 pounds. Total 2,880 lbs of displacement.

The beauty of this design is you can build it any size you want. You can even build a pontoon houseboat.

The pontoons and deck are solid foam core rib contruction and fiberglass reinforced. It is strong enough to operate in rivers and lakes with ease, even taking bumps from floating logs.

Perfect for fishing
Safe to walk around and stand on the side - it is sturdy and will not tip. 

Perfect for swimming, snorkeling and scuba diving
Low to the surface for easy access to the water. Large 78 sq. ft. deck area.

Perfect for overnight camping
It's beam is wide enough to set up a six foot tent. It has the capacity (2880 lbs) to carry up to 5 people and their gear.

The WizCat will handle several power options:

  • 10hp to 50hp outboard motor. (A 6hp outboard motor gives surprisingly good results but a bigger outboard engine is recommended if you plan to take the family. A 5 to 7.5hp is more than sufficient for 1 or 2 persons.)
  • electric trolling motor (or several trolling motors.)
  • aircraft / hovercraft type wind power setup using an air cooled aircraft engine and propeller.
Perfect for cruising
With a place for two (2) 6 gallon fuel tanks under the rear seats of the boat, you're all set for a long cruise range with a 10-20 hp outboard motor. 

This boat trailers, launches and loads at the boat ramp easily.
