Gator Boat Co. Wooden Boat Plans for the Novice Boatbuilder.


BIG MAMMA Model 2-Man Johnboat

The Big Mamma design has been in production for over 12 years and serves as a very functional all around sporting boat.  Stable as a barge, but light in the water, she has a shallow draft and good capacity for a boat that can be loaded into the bed of a small pickup truck.  Good for backwaters, rivers, and lakes, the transom can support an electric or gas outboard.  This design can easily be expanded in size and width, the nature of the plans allows this to be done by simply increasing the dimensions for the floor cutout, then everything else falls into place around that change.  It can be built with or without the livewell. 
Requires no special tools or skills, and built with materials commonly available at local home centers.  This is a quick and easy boat to build and is a great introduction to boatbuilding for those needing a little more room.
